Refining Gold & other precious metals (including silver, palladium & platinum) from CPU's & electronics is typically not profitable unless it's done professionally and in large quantities on a large scale; when processing just a few items the cost is often higher than the value of the gold that is reclaimed. The high gold extractions were obtained by 24 h cyanidation, but longer times were required for extraction of platinum and palladium. Addition of thallium salts at pH 9.5 increased the platinum extraction values to 30–35%.

The high gold extractions were obtained by 24 h cyanidation, but longer times were required for extraction of platinum and palladium. Addition of thallium salts at pH 9.5 increased the platinum extraction values to 30–35%. This is smelted in a small furnace to oxidize virtually all metals present except silver, gold, and platinum-group metals. The metal recovered, called doré, generally contains 0.5 to 5 percent gold, 0.1 to 1 percent platinum metals, and the balance silver. This metal is cast to form anodes and electrolyzed in a solution of silver-copper nitrate. The earlier stages of the mining and recovery of the platinum metals from the Rustenburg Platinum Mines have been reviewed in some detail in this journal (), while the geology of the Bushveld Igneous Complex and the platinum reefs—constituting an enormous reserve of platinum metals—which are mined by the Rustenburg company has also been described (). Platinum is a Silver-white Precious Metal that is rarer than Gold. The Platinum bullion value is high because of its scarcity and its use in industrial applications. Platinum is mined very few places around the world. With mining regulations crippling some parts of the world, Platinum mining remains strong in others.

Today, platinum is still extracted using a technique similar to that 

Extraction of Platinum. 1) Platinum is rarely found on its own, but in combination with other base & precious metals. 2) The extraction process of platinum is quite complex, which includes milling the ore and smelting it at high temperatures. This removes base metals notably the concentrate PGM (platinum Group Metals) – gold, platinum Silver, Gold, and Platinum group metals ores are presented in this second video which educates viewers on exploration and mining of precious metals ores. This is the Mineralogist's focus on the
