Platinum-Group Metal Ores

Platinum-Group Metal Ores. In general, PGM ores are concentrates in the crust found in two different ways, by leaching the metal-rich lava (mantle) deposited into the crust, which is known as chemical weathering, especially in a hot climate where silica and magnesia are leached away, and melting a portion of the mantle, giving rise to ultramafic or basalic …

Recovery of Gold as By-Product from the Base-Metals Industries

Zn leach residues. 1. Introduction. Although most of the gold produced each year originates from primary gold ores or concentrates, a significant amount of gold is recovered as byproduct from the production of base metals (BMs) and from the recycling of scrap. From a gold world production of approximately 2600 metric tons in 2004, about …

Artisanal and Small-Scale Gold Mining Without Mercury

Concentration 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.
