carbon reduction of copper ore

Sulfide Ores an overview ScienceDirect Topics

Unlike mineral sulfide ores, iron ore does not provide an energy source (e.g., ferrous and sulfur compounds) for the oxidative growth of bioleaching microorganisms however, ironreducing bacteria, which gain energy by the dissimilatory reduction of ferric iron to ferrous iron, may be useful in upgrading iron ore slimes.

Thus, neither carbon nor hydrogen is a suitable reducing agent for metal sulphides. Aluminium cannot be used, as reaction with metal sulphide would produce aluminum sulphide, which is not so exothermic. So, sulphide ores are preferentially converted to oxide ores as any reduction method (reduction by C, H 2, AI etc.) could then be conveniently
