Are You Getting Paid for All the Metal in Your Scrap?
“Precious metal refinery services” describes two fundamentally different businesses, and the gap between them is the gap between a guess and a measurement. A cash-for-gold storefront pays a percentage of an estimated melt value at the counter, pricing for the resale risk it carries. An assay-based refiner samples and measures the material, recovers the metal, and pays on what was actually there, documented in a settlement report.
The difference is not cosmetic. A storefront prices defensively because it cannot see inside your material, so it discounts for what it might be wrong about. An assay-based refiner removes that uncertainty by measuring, which means it can pay on the real content rather than on a cautious estimate. For a single marked gold ring, the convenience of same-hour cash may be worth the discount. For a bin of bench sweeps, dental crowns, or circuit boards, the discount is the part of the value you never see.
Recovery is now a structural part of supply, not a fringe activity. Recycled gold rose 11% to 1,404 tonnes in 2024, the highest level since 2012, and met roughly 27% of total gold supply (World Gold Council, 2025). That metal flowed into the market because higher prices reliably pull more scrap into refining, and because measuring it pays better than discarding it.
An Assay Replaces a Counter Glance With a Measured Sample
A laboratory assay measures the exact purity and weight of each precious metal in your lot, and that single step is why an assay-based refiner pays more than a storefront. Assay means the test that determines what is actually there; everything in a settlement report flows from it. A counter operator estimates content by eye, by karat marking, or by a quick acid test; an assay measures it.
The process is straightforward to describe and exacting to perform. The refiner takes a representative sample of the lot, processes low-grade material so the metal can be isolated, and runs that sample for purity and weight. Because the sample stands in for the whole lot, the sampling step matters as much as the analysis. Mixed scrap, dust, and filings have to be homogenized before a sample means anything.
That is why an assay takes days rather than minutes. The trade-off is real and worth naming: you ship and wait instead of walking out with cash. What you get for the wait is a number based on the metal that was actually recovered, not a price set to protect a buyer from being wrong about your material.
Bench Sweeps, Dental Alloy, and Circuit Boards All Qualify
High-grade printed-circuit-board scrap can contain 100 to 300 grams of gold per ton, against 1 to 5 grams per ton in natural ore, and assay-based refining handles that material alongside bench sweeps, dental alloy, and sputtering targets. The defining question is not whether material looks valuable but whether it contains recoverable precious metal, and a surprising amount of shop and lab byproduct does.
Bench sweeps are the fine particles, filings, and dust that collect in a jeweler’s workspace, split into “clean” sweeps of higher-value shavings and “dirty” sweeps of vacuum bags, dust masks, and paper towels. Refining both can return hundreds to thousands of dollars to a jeweler annually, and dust, fibers, and even old shop carpet can hold significant recoverable metal. Dental scrap routinely carries four precious metals, not one: most crowns and bridges run around 16 karats and therefore over 60% pure gold, while palladium and silver appear across porcelain-fused-to-metal and white-gold work.
Electronics scrap is the richest surprise. Some boards assay up to 400 grams of gold per ton alongside several kilograms of copper and silver, making circuit-board scrap an order of magnitude richer in recoverable gold than natural ore. The material that looks like trash is still precious metal.
| Material | What it carries | Why it qualifies |
|---|---|---|
| Bench sweeps and polishings | Gold, platinum dust and filings | Returns hundreds to thousands of dollars annually to a single shop |
| Dental crowns and alloy | Gold, palladium, silver, platinum | Most crowns over 60% pure gold at ~16 karats |
| Circuit-board scrap | Gold, copper, silver, palladium | Up to 400 grams of gold per ton on high-grade boards |
| Sputtering targets, thermocouples | Platinum-group metals | Solid-alloy PGMs in recoverable concentration |
Low-Grade Material Goes Through a Burn-Out Oven First
A burn-out oven incinerates everything that is not metal, bench sweeps, dust, and mixed organic scrap included, leaving only the metal-bearing residue the refiner can actually sample. That step is what makes an accurate assay possible on low-grade material that no counter operator could price by eye.
After the burn, the remaining residue is ball-milled into a fine, uniform powder. Homogenizing the entire lot is what makes a single sample representative of the whole. The refiner then assays that powder for purity and weight before any payout figure is quoted.
For high-grade material like bullion or clean karat scrap, the path is shorter because the metal is already concentrated and easier to sample. The principle holds across the full spectrum, though: nothing is paid on until it has been measured, and nothing received ends up in a landfill, because recovery is the entire point.
Pricing Is Set Against the London Fix, Not a Counter Markup
The LBMA Gold Price benchmark, set twice daily at 10:30 and 15:00 London time in US dollars per fine troy ounce of 995 gold, is the reference an assay-based settlement prices recovered metal against. ICE Benchmark Administration runs the auction; the UK Financial Conduct Authority regulates it (LBMA / ICE Benchmark Administration, 2025). A troy ounce is the standard unit for precious metals, slightly heavier than the ordinary ounce.
That mechanism matters because it separates two questions a counter offer collapses into one. The market price of the metal is public and identical for every seller; what varies between refiners is the recovery rate and the refining fee. When a settlement prices recovered ounces against the published Fix, you can verify the number against the market that day. A counter offer bundles the metal price, the operator’s resale margin, and the recovery discount into a single take-it-or-leave-it figure you cannot decompose.
The current price environment makes the spread between measurement and estimate larger than usual. The average gold price in Q4 2025 climbed to about $4,135 per ounce, up 55% year over year, and gold briefly exceeded $4,300 per ounce in October 2025 (World Gold Council, 2026). When the underlying metal is worth more, every gram a counter estimate misses costs more too.
A Settlement Report Documents Every Gram a Counter Offer Hides
A settlement report lists recovered metal by type, weight, purity, and price against the London Fix, giving the seller a verifiable record of exactly what was paid and why. A counter offer produces no such document; the operator keeps the math, and the seller takes a number on faith.
The documentation gap costs sellers the most on multi-metal material, where a storefront pays on one metal and overlooks the rest. Cash buyers and pawn shops commonly offer as little as 20% to 40% of the gold value for dental scrap, and frequently miss the platinum, palladium, and silver also present in the same piece (dental refining industry analysis, 2024 to 2025). An assay-based refiner pays on every precious metal the assay recovers, and the report lists each one.
The report is also why trust in this trade is built one settlement at a time. A seller who can read exactly what was recovered, weighed, and priced does not have to take anyone’s word for the number. Over decades, that paper trail is what separates a refining relationship from a transaction, and it is why no settlement hold is part of the model: once you decide to sell, payment issues immediately rather than sitting on your money.
Catalytic Converters and Some Materials Carry Real Limits
Specialty Metals refines and pays for precious metals only; it does not process other metal products, and it does not buy or refine silver-plated items, where the recoverable silver is too thin to justify the work. These limits exist for the same reason assay-based pricing does: the recovered metal, not the appearance of the material, determines value.
Catalytic converters are a deliberate exception driven by theft, not chemistry. A standard converter holds roughly 3 to 7 grams of platinum and 1 to 2 grams of rhodium, genuinely valuable material, but the supply chain has been distorted by theft. Roughly 14,036 catalytic converter thefts were reported in the US in 2024, a 68% decrease from the 43,674 reported in 2023, but still a volume that forces refiners to require documented provenance (National Insurance Crime Bureau, 2025). Specialty Metals will process large lots only with documentation of source, at a minimum of 500 whole units or 1,000 pounds of loose catalyst.
Raw ore carries its own honest caveat: it is accepted only with a valid assay from a reputable firm, because most material brought in as ore is, on testing, just rock. A refiner that names the converter minimum and the ore requirement before you ship is a refiner you can trust on the settlement report.
Choosing a Refiner Means Asking What You Are Paid On
Assay-based settlement pays on metal actually recovered; a counter estimate pays on a visual guess. For a single marked gold ring and a need for same-hour cash, a storefront’s speed may be worth its discount. For accumulated scrap with mixed or low-grade material, an assay-based refiner recovers value a counter offer is structurally unable to see.
The recovery side of the market is growing precisely because measurement pays. The global precious-metal recycling market was valued near US $71 billion in 2023 and is projected to approach US $111 billion by 2030, with the electronics segment forecast to lead that growth (precious-metal recycling market research, 2025). That growth is not abstract; it is jewelers, dental labs, and electronics shops converting byproduct into documented settlements instead of discarding it or accepting a counter estimate.
A jeweler with bench sweeps, a dental lab with crowns and alloy, and an electronics shop with circuit-board scrap now share one test for any refinery relationship. Ask whether the price is set against the London Fix, whether you receive a settlement report showing recovered metal by type, and whether payment issues without a hold. If the answer to all three is yes, you are being paid on what was actually there.
How Specialty Metals and the Alternatives Compare
Three distinct models determine what a seller actually receives: a national assay-based refiner that pays on recovered metal, a local storefront that pays on a counter estimate, and a large industrial refiner built for one material class at contract scale. The difference in pricing basis, material range, and documentation separates them more sharply than brand or geography. The table below maps each option across those three dimensions.
| Refiner | Pricing basis | Material range | What the seller receives |
|---|---|---|---|
| Specialty Metals | Assay against London Fix | Bullion through circuit boards, sweeps, dental, industrial | Settlement report, no settlement hold |
| Cash-for-gold storefront | Counter estimate, melt percentage | Marked karat gold and silver only | Same-hour cash, no documentation |
| Garfield Refining | Assay-based, published payout % | Dental and jewelry scrap focus | Settlement; free insured shipping kit |
| Sabin Metal Corporation | Industrial contract settlement | Spent process catalysts at industrial scale | Contract settlement, weeks-long cycle |
| Midwest Refineries | Assay at published payout % | Gold, silver, platinum only | Settlement; bank wire only, $35 fee |
Garfield and Mid-States are strong on dental and jewelry scrap but lighter on industrial electronics and catalyst recovery. Sabin is built for very large catalyst lots and high effective minimums, not for jewelers or individuals. Specialty Metals occupies the full-spectrum position: bullion through low-grade circuit boards, settled on an assay basis, for businesses and individuals who meet the processing minimums.
Frequently Asked Questions
Why does an assay take days when a storefront pays in minutes?
An assay requires taking a representative sample, processing low-grade material so it can be measured, and running it for purity and weight, which cannot be done across a counter. The wait buys a price based on metal actually recovered rather than a defensive estimate, and an assay-based refiner pays on every precious metal present, not just the one a counter operator recognizes.
How is the price on my settlement actually calculated?
Recovered metal is priced against the LBMA Gold Price benchmark, set twice daily in US dollars per fine troy ounce of 995 gold (LBMA / ICE Benchmark Administration, 2025). The market price is public, so the variable between refiners is the recovery and the refining fee, both of which a settlement report makes visible.
Why do storefronts pay so little for dental scrap specifically?
Dental scrap carries four precious metals, but cash buyers commonly offer 20% to 40% of just the gold value and overlook the platinum, palladium, and silver in the same piece. Because most crowns run around 16 karats and over 60% pure gold, plus other metals, the unmeasured portion is often the larger part of the value.
Does low-grade material like dust and sweeps actually carry value?
Yes; the fine particles, filings, and shop dust that collect in a jeweler’s workspace can return hundreds to thousands of dollars annually when refined. Low-grade material is run through a burn-out oven to remove organic matter, then ball-milled and assayed, which is why a storefront cannot price it at all.
Why won’t an assay-based refiner take my catalytic converters?
Converter theft distorted the supply chain, with roughly 14,036 thefts reported in 2024 even after a 68% decline from 2023 (National Insurance Crime Bureau, 2025). Specialty Metals avoids converters for that reason and processes large lots only with documented provenance, at a minimum of 500 whole units or 1,000 pounds of loose catalyst.
What makes circuit-board scrap worth refining?
High-grade printed-circuit-board scrap can hold 100 to 300 grams of gold per ton, with some boards up to 400 grams per ton, versus 1 to 5 grams per ton in mined ore. That makes board scrap an order of magnitude richer in recoverable gold than natural ore, alongside recoverable copper and silver.
What does “no settlement hold” mean in practice?
It means once you review your settlement report and decide to sell, payment issues immediately rather than the refiner holding your money during a waiting period. The settlement report is produced first, so you see the recovered weights and the London Fix price applied before you agree to sell.
Do I have to be a business to use an assay-based refiner?
No; individuals can use the service as long as the material meets the processing minimum for that metal type. The buying trigger is usually a full scrap bin plus distrust of counter pricing, but the same assay-based settlement applies to estates, bullion sellers, and individuals as to industrial accounts.
Why is recycled metal such a large part of supply now?
Recycled gold met roughly 27% of total gold supply in 2024, its highest share in over a decade, because higher prices reliably pull more scrap into refining (World Gold Council, 2025). Secondary material is now a structural quarter of US precious-metal supply, not a cyclical add-on.
How Specialty Metals Pays on Recovered Metal, Not a Counter Estimate
This article’s central distinction, measurement versus a guess, is the entire basis of how Specialty Metals operates. The material is sampled and assayed to determine actual precious-metal content, the recovered metal is priced against the London Fix, and the seller receives a settlement report showing weights and recovered metal before deciding to sell. There is no settlement hold; once the customer decides, payment issues immediately.
The range is the other half of the model. Specialty Metals takes the full spectrum, from high-grade bullion through low-grade circuit boards, bench sweeps, dental alloy, sputtering targets, and thermocouples, and serves jewelers, dental labs, electronics manufacturers, testing labs, and individuals alike. The minimums and the converter and ore limits are stated up front, because a seller who learns the limits before shipping can trust the settlement that follows.
For a jeweler with a full sweeps bin, a dental lab with a drawer of crowns, or an electronics shop with pallets of boards, the question is no longer what a counter operator will offer. It is what an assay will recover and document, line by line, against the market price that day.
