Primary production at Impala Platinum mine in South Africa. IMAGE CREDIT: Mining Operations, Implats. For example, in South Africa, PGM-bearing ores generally have a low PGM content of between 2 and 6 grams per tonne and it will typically take up to six months and between 10 and 40 tonnes of ore to produce one ounce (31.1035g) of platinum.2

Platinum Refining Process

Platinum refineries provide an economical and environmentally friendly precious metal recovery service. We buy platinum scrap and separate the pure platinum from other precious metals and waste materials. …

Gold processing

The drops of lead dissolve the gold, silver, and platinum-group metals, then coalesce and gradually descend through the sample to form a metallic layer at the bottom of the crucible. After cooling, the lead "button" is separated from the slag layer and heated under oxidizing conditions to oxidize and eliminate the lead.
