· Use of NaHS and silver ions has been reported to improve gold recovery at the Los Pelambres mine in Chile (Chryssoulis 2001 ). Sulfide ions appear to act as flotation activators at low concentrations less than 10 −5 M, whereas at concentration above 10 −5 M, it acts as a depressant (Aksoy and Yarar 1989 ).

· By enhancing the quality of lower-grade raw materials through beneficiation, downstream processes also become more viable. Various production routes are available to transform iron ore into liquid steel, as shown in Figure 1. The selected route depends to a large extent on the quality of the iron ore, energy source and related costs.

1.1 Physical Beneficiation. Beneficiation of copper ores is done almost exclusively by selective froth flotation. Flotation entails first attaching fine copper mineral particles to bubbles rising through an ore–water pulp and, second, collecting the copper minerals at the top of the pulp as a briefly stable mineral–water–air froth.

Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of water and flushed away.
