Gold processing 101
At current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price, but in the current gold …
Copper Mining and Processing: Processing Copper Ores
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and …

Platinum (element #78, symbol Pt) is a dense, silvery-gray metal. The platinum group of elements consists of metals with similar physical properties as platinum and these elements are among the rarest in the Earth's crust. They have high melting points, are dense or heavy and are non-reactive with other elements.

OVERVIEW OF PGM PROCESSING
Platinum Group Metals (PGMs) are recovered through underground and open pit mining from poly-metallic sulphide ores containing PGMs, Nickel, Copper and other metals: Platinum (Pt), Palladium (Pd), Rhodium (Rh) and Ruthenium (Ru) are the most prevalent of the six PGMs, with Iridium (Ir), and Osmium (Os) found in much smaller quantities.
The Mining Process | OceanaGold
The Mining Process. 1. Mining – Open Pit and Underground — To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

Gold Smelting & Refining Process
The charge is heated slowly until boiling point of mercury is reached. At this point the mercury is eliminated and condensed in cooling tubes passed through water. Obviously, some losses can be produced and this can be estimated as 0.065 grams per 255 grams of mercury. The process takes two to three hours.
