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.
Extraction of Copper: Detailed Process
Minerals are concentrated in certain types of geologic formations (ore bodies), which must be mined, processed, and purified in order to increase the metal's applicability. The process of extraction of copper from its ores and preparing copper metal or chemical compounds for use in various goods is known as copper processing.
