Recovery of metals from pyrite

A process is disclosed for the recovery of a metal from a pyrite-bearing material. The process comprises thermally decomposing the pyrite-bearing material so as to produce a material comprising pyrrhotite (FeS). The process also comprises leaching the material comprising pyrrhotite with an acid such that the iron in the pyrrhotite is oxidised to a +3 oxidation state, elemental sulphur is producedand the metal is released from the pyrite-bearing material. 公开了从含黄铁矿的材料中回收金属的方法。该方法包括使含黄铁矿的材料热分解，以产生包含磁黄铁矿(FeS)的材料。该方法还包括用酸浸出包含磁黄铁矿的材料，使得磁黄铁矿中的铁被氧化成+3氧化态，产生元素硫，并且从含黄铁矿的材料中释放金属。
