Sulfatizing roasting for copper and cobalt production

Sulfatizing roasting for copper and cobalt production

Sulfatizing roasting belongs to a production process for copper and cobalt from sulfidic ores. Figure 1 shows a simplified block flow diagram of the location of the roasting stage in the entire process map. The objective of roasting is a selective sulfation of copper and cobalt. Iron is fully oxidized to ferric oxide.

cobalt processing Uses Supply amp Facts Britannica

History. Ores containing cobalt have been used since antiquity as pigments to impart a blue colour to porcelain and glass. It was not until 1742, however, that a Swedish chemist, Georg Brandt, showed that the blue colour was due to a previously unidentified metal, cobalt. In 1874 the output of cobalt from European deposits was surpassed by production in New Caledonia, and Canadian ores assumed ...

COBALT PROCESSING DEVELOPMENTS K G Fisher

From the 1950s on, world cobalt production was dominated by the Congo Zaire, now DRC and Zambia, peaking in 1986. Thereafter this source declined dramatically but, fortunately, cobalt from emerging nickel producers increased substantially such that cobalt produced from combined nickel sources sulphides plus laterites became the world leader.
