How to Separate Gold from Pyrite. ... The richness of the ore, however, made even this result unsatisfactory, and a process of chlorination was adopted in practice. A similar case was noticed by Mactear in South America, where a limonite ore which only yielded from 35 to 40 per cent, of its gold when treated in Huntington pans, was made to ...
At the current time, it is more economical to smelt copper ore rather than to use bioleaching, since the concentration of copper in its ore is in general quite high. The profit obtained from the speed and yield of smelting justifies its cost. Nonetheless, at the largest copper mine of the world, ndida in Chile the process seems to be favorable.

The most costeffective process is to create adsorption of the dissolved gold and/or silver onto activated carbon, resulting in an easier solidsolid separation based on size. To achieve this the ore particles must typically be smaller than 100 µm while the carbon particles must be larger than 500 µm.
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.
