Today’s post is going to sound a little bit like a chemistry lesson, because chemicals are used to recycle platinum and palladium from liquids where they reside.
Most of the time here at Specialty Metals Smelters and Refiners, we use heat to extract precious metals. This is one time when that’s not the case.
How Do Palladium and Platinum Get into Liquids?
- As a byproduct of mining operations – Acidic baths are often used to leach copper, nickel, uranium and other metals from ores. In many cases, the acidic liquid that is left after processing contains trace elements of other precious metals too, including platinum, palladium or even gold.
- From plating baths – If your operations include tank-plating palladium or platinum onto other metals, your used solutions can still contain valuable quantities of those metals. In some cases, as much as 10 ounces of metal has been recovered from one cubic foot of used plating solutions. That’s a lot of valuable precious metal.
- From solutions left over from platinum recycling processes – If you employ wet chemical methods to extract palladium, platinum and rhodium from recycled catalytic converters, your used acids and washing liquids could contain recyclable quantities of precious metals.
How Are Precious Metals Extracted from Liquid Media?
It all comes down to chemistry. First, we analyze your liquids to determine the quantities of precious metals that they contain. Next, we introduce the right chemicals into your liquids in the right way – under safe, monitored laboratory conditions, of course. The results can be amazing, as ounces of palladium and platinum precipitate out of liquids that looked like little more than opaque sludge.
Incidentally, Dow Chemical and other companies manufacture a number of high-quality chemicals that are used in these operations. All processing is done in the most advanced, environmentally respectful conditions that comply with all laws.
Today’s Practical Tip . . .
Don’t let those metals go unextracted, because they are worth a great deal of money. Call us at 800-426-2344; tell us what liquids you have. We’ll help you set up a plan to analyze your liquids, extract precious metals from them – and put dollars in your pocket.
