17 Jul 2014 and a part of sulfide minerals may be lost and thus making the process economy less advantageous. Such case is found in the copper ore
In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals.
Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, This is used to make sulphuric acid via the Contact Process.
