The platinum group metals, together with some gold, total about fifty ounces to the ton. The complete process of extraction consists essentially of enriching this matte to approximately 65 per cent content of platinum metals and then treating this concentrate with acids to separate the individual platinum group metals from each other, followed by final refining.

Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly. On average, it takes between 10-20 years before a gold mine is even ready to produce material

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.

While the entire amount of gold ever mined totals approximately 190,000 tonnes (the stock), annual production is about 2,900 tonnes (the flow). If you divide the stock by the flow you get a stock-to-flow ratio of 66 years. Silver meanwhile has a stock-to-flow ratio of ~22. Platinum and palladium have a ratio of 1.1 and 0.4 respectively.

To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls.
