Pyrite Oxidation Kinetics - How Fast does Pyrite Oxidize

Pyrite is readily covered by iron hydroxides. Both ferrous and ferric hydroxides undergo irreversible reactions involving one electron. On aging ferric hydroxide transforms into more stable species which is then reduced to ferrous hydroxide at potentials more reducing than the reduction potential of ferric hydroxide.


Roasting in Metallurgy - Mineral Processing & Metallurgy

At one of the Californian chlorination mills it was found by experiment in 1882 that nearly 50 per cent, of the gold and 28 per cent, of the silver were being lost by volatilisation. In this case the pyrites was roasted on two hearths for thirty-six hours, 1 per cent, of salt being added four hours before the charge was drawn.
