Extraction and Refining of the Platinum Metals

From this stage onwards the concentration of the platinum group metals is more rapid and the processes entirely chemical. First the slime is subjected to roasting and leaching attacks to remove the last of the copper, nickel, iron and sulphur. This produces an enriched slime running approximately 65 per cent of the platinum group metals and gold.

2020. 4. 13.  Platinum ore can be obtained through controlled explosions or by advanced mining techniques. Once it has been mined, the platinum is extracted from the ore in the same way. 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

2010. 7. 1.  When ores are combined in blends it is commonly assumed that the metallurgical performance of the blend is additive, i.e. equivalent to the weighted average sum of that for pure ores in the blend. For example, the contribution to overall flotation recovery for an ore in a blend is considered equal to the recovery of the pure ore multiplied by its mass fraction.
