[7] Cobaltite can be separated from other minerals by selective, pH controlled, flotation methods, where cobalt recovery usually involves hydrometallurgy.
Four methods of nomenclature are used: [3] [5] The initial letters of a name, for example: cyanotrichite: Cya and mitscherlichite: Mits.

Raw meat products contain up to 73% water. [4] The meat is cooked by the evaporation of this water. When the water is vaporized it leaves the meat through pores in the surface of the meat. Another source of water vapor is the Maillard Reaction. This reaction is responsible for why meat, and many other food products, turn brown when cooked.
