How is platinum extracted from its ore

19/09/2014· Extracting Platinum from these ores is arguably one of the most capital and labour intensive operations in the world. On average, it takes up to six months and up to 12 tonnes of ore to produce an industry standard troy ounce, which is 31.135 grams of pure metal. However, in mining using 4.5 tonnes of ore to produce one gram of platinum would not be considered abnormal.

Platinum Mining and Refining | Education

Refining platinum ore is a costly and laborious process. It can take from eight weeks to six months to process a batch of ore, and it can take up to 12 tons (11 tonnes) of ore to produce a single troy ounce of platinum. Once the broken ore is transported to the surface of the mine, it is crushed by machinery into small pieces and mixed with water and chemicals, which bind to the platinum and other metals.
