PlatinumGroup Metal Ores an overview | ScienceDirect Topics

Because the concentration of Pt in its ore is only a few parts per million, its mining and smelting are energy and labor intensive and costly. However, the grade of PGMs in the Merensky and UG2 Reefs is 100 times higher than that in the earth''s crust. The quality of the PGMs ore in these veins is higher than that of the ores from other mines.

Why is it difficult to achieve separation of constituents of a ... Quora

The short answer is because of the second law of thermodynamics. The mixture is at the lowest energy state. The separate constituents are the higher energy state. It is natural and relatively easy to go from a high to low energy state. You have to add energy (work, difficulty) to get back to the high energy state. Athreya Suresh Babu,

Artisanal and SmallScale Gold Mining Without Mercury

Jan 12, 2022Concentration means increasing the amount of gold in ore or sediment, by selectively removing lighter particles. If employed effectively, concentration methods can eliminate or greatly reduce the need for mercury. Before concentration can begin, ore must be crushed or milled to liberate gold particles from rock and to decrease grain size.
