Rcovery of gold in pyritic ores - Mine Engineer.Com

The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite). The characteristics of primary pyrite are a absence of porosity, an extreme brittleness, a resistance to oxidation, and the existence of gold possessing a weak susceptibility to magnetism (due to a fine coating of a iron compound).

Pistorius (2005) as a method to optimise both the grade and recovery of the lead and zinc concentrates recovered from this ore. Pyrite (iron) recovery for all the three milling environments was very high and showed little change as the grinding fineness increased, probably resulting from the good floatabilities of pyrite with SNPX.

Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger ...
