Locations of Deposits

Platinum Group Elements (PGEs) Platinum group elements are mined from mafic and ultramafic igneous rocks, in alluvial and placer deposits, hydrothermal veins, and contact mineralization deposits. They also occur in the mineral cooperite and in igneous rocks (Pohl, 2011). Here is a map of all PGE deposits in the world (Goodfellow, 2006)

Platinum is produced in South Africa by Amplats,

Since the identification of economic deposits of platinum in South Africa in 1924 by Hans Merensky, a number of platinum mines have come and gone, and some have merely changed identity. 13 South Africa currently has four integrated primary platinum producers, namely Amplats 4,5 (Anglo American Platinum Corporation Ltd, formerly Rustenburg Platinum Hings Ltd), Impala Platinum, 6 Lonmin Platinum 7 (which includes Western Platinum), and Northam Platinum

2/10/20170183;32;Another innovation able to manage chromerich ores is the ConRoast process. This process involves removing and capturing sulphur from the concentrate prior to smelting in a DC arc furnace. Roasting a concentrate makes smelting more environmentally friendly; it also enables furnaces to accept any proportion of chromite, resulting in more efficient and costeffective platinum production

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.

How Is Platinum Extracted? Reference

4/8/20150183;32;The platinum ore is not pure, so it is first crushed. This produces many tiny particles that can be treated. Air particles then bubble through an aeration tank and adhere to the platinum particles. This brings the platinum particles, with the air particles, up to the top of the tank. The layer of particles that ultimately forms can be skimmed off and refined into platinum.
