Modelling and process optimisation of antimony

2012-3-31  Antimony is a chalcophilic metalloid belonging to group 15 of the periodic table. It occurs naturally at a trace level in the environment. Antimony-bearing minerals are commonly found in small concentrations in many sulphide ore deposits. Tetrahedrite (Cu12Sb4S13) is an antimony mineral which is often found in association with copper sulphide ores.
