Jun 24, 2017 Most ore milling operations have work indices ranging from 10 to 12, with extremes between 8 and 22. Because most of the platinum-group bearing sulfides occurred as fine grains and required grinding to approximately 200-mesh for liberation, flotation was investigated as a means for concentrating the metal values.
Primary production at Impala Platinum mine in South Africa. IMAGE CREDIT Mining Operations, Implats. For example, in South Africa, PGM-bearing ores generally have a low PGM content of between 2 and 6 grams per tonne and it will typically take up to six months and between 10 and 40 tonnes of ore to produce one ounce 31.1035g of platinum.2
Jul 25, 2021 Platinum ore is an ore that yields platinum and small amounts of iridium. It is unobtainable by default. Obtaining. Platinum ore does not occur in the world by default, and thus cannot be legitimately obtained. However, it may be configured to generate in the world in modpacks. Platinum ore must be mined with a diamond pickaxe or better. If it ...
The present invention is a process to recover precious metals from sulfide ores. It involves chlorinating a mixture of an ore concentrate and salt to form a liquid melt. The salt preferably contains potassium chloride. This chlorination is carried out at a temperature between 300 and 600 C. while stirring. The process converts precious metals in the elemental and sulfide forms into ...
