Figure 7 shows data collected from a platinum plant, where the ore treated was very difficult to mill. In the first two days, the mill experienced numerous power dips (overloads), and on at least seven occasions the feed to the mill had to be completely stopped to grind the mill out. Also, the mill load varied in the range of 125 to 165 tons. These
Platinum mining on a large scale began around 1926, and before the 1920s were over, no less than seven mining operations had started in South Africa. The platinum ores were mostly processed by traditional milling and gravity-table concentration.
A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

Jan 23, 2012· Ore is first crushed and then undergoes various processes depending on the nature of associated minerals. Processing low-grade ore is relatively simple while higher grades require more extensive processing. Step #8 – Refining (off-site) Once basic processing is done, the ore is taken to a refinery where the remaining impurities are stripped out.
