Sulphide concentrate leaching

The question as to whether concentration shall be included in the treatment of a given ore will often depend on the possibility or otherwise of recovering the precious metals from the concentrate at the mine It may be suggested that if the concentrate can be cyanided after being separated from the gangue why can it not be equally well cyanided if allowed to remain in the pulp going to the...

ACANTHITE/ARGENTITE Silver Sulfide

Acanthite is the most important silver ore next to galenaActually there is an argument to be made that acanthite could be the most important silver ore Galena is a lead ore that often contains enough silver usually about 1 that when it is processed for its lead content the by-product silver supplies the majority of the world s needs But most if not all the silver in argentiferous galena...
