technology is being increasingly used to address three major challenges of the mining industry: (1) increase in the global mineral consumption of minerals (for instance, the production of bauxite increased six-fold during the last two decades), (2) the reduction in the prices of minerals (for instance, the price of gold which has been oscillating around usd 350–400/oz, is currently around usd 300/oz), (3) huge quantities of ever-lower grades are being processed by bulk mining

pure pyrite floats without activation because of dixanthogen formation as a result of catalytic oxidation of xanthate on clean (fresh) pyrite surfaces. however, most floated pyrite is either copper or lead activated which means that incipient surface oxidation had to take place to form islands of pyrrhotite, which then became sites for activation by cu or pb.
