Solution
The branch of science and technology concerned with the use of high temperatures to extract and purify metals .It consists of the thermal treatment of minerals and metallurgical ores and concentrations to bring about physical and chemical transformation in the materials to enable recovery of valuable metals
Pyrometallurigical processes are generally grouped into one or more of the following categories :
Calcination :calcination is the thermal decomposition of materials
Smelting:smelting involves thermal reactions in which at least one product is a molten phase .
Refining :refining is the removal of impurities from materials by a thermal process .This covers a wide range of processes ,involving different kinds of furnace at a plant
Hydrometallurgy is a method for obtaining metals from their ores .It is a technique within the field of extractive metallurgy involving the use of aqueous chemistry for the recovery of metals from ores ,concentrates ,and recycled or residual materials .
It is typically divided into three general areas
1.Leaching
2.solution concentration and purification .
3.metal or metal compound recovery
