There are six metallic elements called the Platinum Group Metals (pgm) which are platinum, palladium, rhodium, ruthenium, iridium and osmium. These are all extracted during the mining process. Because of the rarity of pgm and its tendency to combine with other metals, the mining process often yields far more nickel or copper than it does platinum.

Heap leaching is an industrial mining method to dig out precious metals and copper compounds from ore. Process of heap leaching. The mined ore is crushed into tiny chunks and heaped on an impermeable plastic and/or clay lined leach pad where it may be irrigated with a leach solution to melt the valuable metals.

Metals Processing For over 50 years, metals processors around the world have come to rely on Air Products' industrial gases, gas atmospheres and technical support to help improve product quality, reduce operating costs and increase production.

Ore processing is a 24 hour operation. Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore.

The Zinc Mining Process. Once it's removed from the earth, the concentrate is roasted at a temperature of 950 degrees Celsius, causing zinc, sulfur and iron oxidization. After the zinc and iron oxides are reduced to powder form and leached with diluted sulfuric acid, the solution is neutralized and contaminants are removed via filtration.
