At Specialty Metals, Smelters, and Refiners, we understand the importance of discerning the true nature of your precious metal scrap. Whether you're a jewelry enthusiast, a medical device manufacturer, or a collector, knowing whether your material contains platinum, iridium, or a combination of both is essential for ensuring its value and utility.

Precious metals can be found in old dental appliances, especially in old crowns, bridges, porcelain-to-metal facings, fillings, and gold wire.

How much gold, silver and other precious metals can you find in dental scrap, and what kind of appliances should you be looking for? Let’s break it all down by looking at the precious metals that have been used to make dental appliances.

Are coins and bullion bars good investments? In today’s post, you will learn what you need to know to make a good decision about whether to sink your money into these popular investments. 

The platinum group metals - platinum, palladium, rhodium, iridium, and ruthenium look pretty much the same. They are all bright, shiny white metals that do not tarnish. And if you’re dealing with platinum group metal scrap – the stuff that is left over after different industrial processes – it all looks pretty much the same. 

Have you noticed a big change in computers over the last few years?

We’re not talking about the fact that DVD/CD drives have disappeared from most of them – even though that is true. Nor are we talking about the fact that there is no longer a place to plug in an ethernet cable. 

Another way to identify precious metals . . . 

Do Precious Metals Have Distinctive Smells or Tastes?

We have written on this blog before about what gold, silver, platinum, and other metals look like. Gold is yellow and doesn’t tarnish, for example. Silver is white in color and does collect a layer of chalky tarnish. And platinum is white in color and doesn’t tarnish. 

The platinum group metals (PGMs) consist of six chemically and physically similar elements: platinum (Pt), palladium (Pd), rhodium (Rh), ruthenium (Ru), iridium (Ir), and osmium (Os). These metals are often alloyed with each other and with other elements to create materials with specific properties for various industrial and other applications. 

Platinum engagement rings are not rare. Maybe you called off an engagement and your former fiancé gallantly said, “I gave the ring to you . . . it’s yours, so keep it.” Or maybe you find some platinum engagement ring blanks (rings that have not yet had stones mounted in them) in a jewelry manufacturing company that went out of business. 

What do you get when you mix platinum and iridium, two ultra-valuable white, shiny metals? You get a very valuable alloy with high density and resistance to corrosion and oxidation, even at high temperatures. Those characteristics make the alloy particularly useful. 

Rhodium oxide is a chemical compound formed by rhodium, a rare and precious transition metal, and oxygen. There are multiple oxides of rhodium, but the most common is rhodium(III) oxide, which has a chemical formula Rh2O3. In this compound, rhodium exhibits a +3 oxidation state.

Recycling platinum and platinum scrap is not a job for hobbyists. Some potential risks include:

We haven’t written about sputtering targets in some time. But it’s worth revisiting the topic because money can be made recycling them. Sputtering targets are a very specialized kind of platinum scrap – and in some cases, of gold and silver as well. 

We recently asked Dan Fried, Founder and CEO of Specialty Metals Smelters and Refiners, to name a few places where platinum can be found. Some of his advice was surprising and if you follow it, we predict you will find platinum that you can recycle for money. 

We’ve written in the past about recycling platinum laboratory equipment. Back in 2014, for example, we published a post entitled, “Bright Shiny Platinum Could Be Hiding in your Dented and Dirty Old Labware.”

Let’s fast forward to 2023. In the video that accompanies today’s blog post, we interview Dan Fried, President and Founder of Specialty Metals Smelters and Refiners, about making money recycling platinum and iridium crucibles. 

What is the most valuable and sought-after precious metal today?

If you ask a group of precious metal investors that question, chances are that most of them will say, “Iridium!” And there are reasons for that. One is that iridium is now trading for more than $6,000/Troy Ounce, which is a very high price. Another reason is that most of those investors have never seen iridium because it is so rare. So it’s mysterious, kind of like unicorns. Everybody can describe a unicorn, but nobody has ever seen one. 

Platinum alloys are valuable and are commonly used in various industrial applications, including electronics, jewelry, and more. And if you can find platinum and platinum alloy scrap, chances are good that you will be able to recycle it for a good payback. After all, platinum is now trading for $908.00/troy ounce. That means that even a small quantity of platinum scrap you find can often result in a big profit for you. 

For first-time investors, the best precious metals to consider buying are gold, silver, and platinum. These metals have a long history as stores of value and are easier to acquire and sell than other precious metals. Here's why these metals should be among your first investments if you are just starting out as an investor.

The platinum family metals, also known as the platinum group metals (PGMs), are a group of six elements that share similar chemical properties. These metals are highly valuable and have various industrial applications, making them attractive for investment purposes. 

The six platinum family metals are:

There are low-risk investments you can make in precious metals and precious metal scrap. For example, you walk into an antiques mall and buy a pair of old cufflinks for $50.00. You’re not sure whether they are made of 14K gold, 18K gold, or are just gold-plated. But you put your money on the counter and plan to learn more about the cufflinks later. After all, they cost you just a small amount of money. And if you turn out to double or triple your investment, then you’ll be happy. 

Is platinum toxic?

In its pure form, platinum is inert and does not react with most chemicals or substances, including acids and bases. This property makes it highly resistant to corrosion and tarnish. Consequently, platinum is often used in medical and dental implants, such as pacemakers, stents, and dental crowns, due to its biocompatibility and resistance to corrosion.
