Mineral processing

Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.

Pyrrhotite Oxidation Pyrometallurgy Roasting, Smelting

Heating Pyrrhotite at 320 degrees C. will destroy its magnetism. Heating in the presence of Oxygen (no water) will have the following reaction equation (balanced) ; 3FeS + 5O2 = Fe3O4 + 3SO2. This is the process that used to be used at INCO in Sudbury, Ontario, Canada to convert FeS to Magnetite, which was then pelletized and sold as Iron Ore.

Metallurgy depends on the separation of a metal compound from its ore and reduction to the metal at high temperature (pyrometallurgy) or in aqueous solution (hydrometallurgy). Settling and flotation have been used for thousands of years to separate particles of dense metals such as gold, using the technique known as panning, in which a sample of gravel or sand is swirled in water in a shallow metal pan.
