cobalt processing, preparation of the metal for use in various products. Below 417 °C (783 °F), cobalt (Co) has a stable hexagonal closepacked crystal structure. At higher temperatures up to the melting point of 1,495 °C (2,723 °F), the stable form is facecentred cubic. The metal has 12 radioactive isotopes, none of which occurs naturally.

Cobalt is a chemical element with the symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silvery metal .

A comparative analysis of the evolution of ore grades, energy costs, and market prices was additionally carried out. According to the simulations, extracting nickel from sulfide ore tailings would be profitable if the price doubled. As for Cobalt, it would only be feasible if the market price increased considerably.
