cobalt processing, preparation of the metal for use in various products. Below 417 °C (783 °F), cobalt (Co) has a stable hexagonal close-packed crystal structure. At higher temperatures up to the melting point of 1,495 °C (2,723 °F), the stable form is face-centred cubic. The metal has 12 radioactive isotopes, none of which occurs naturally.
Gold/silver base metal concentrate deportment. Smelters typically pay >95% (Au) and 90% (Ag) in copper and lead concentrates, but will only pay 60-70% (maximum, depending on degree of Pb/Zn smelter integration) for gold and silver in zinc concentrates. Cost drivers are also important in flowsheet selection, and are summarised in Table 3.
Processing the mined ore. In the mills, the ore is crushed into particles of less than 300mm and then ground to a slurry of less than 0.1mm. The slurry is then pumped to flotation plant where various minerals get separated. Flotation is carried out in tanks called flotation cells. Different minerals get separated at different stages.
