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. The best-known is cobalt-60, which has a half ...

The technique of ion flotation provides a simple physical method for concentrating the ions present in very dilute liquors. The ions in the liquor, with the aid of a suitable surfactant, adsorb at the surface of rising air bubbles, and report to a froth product.
