cobalt production process from copper cobalt ores

Production of cobalt from copper-cobalt ores on the African Copperbelt – An overview - ScienceDirect

As mining continues, the nature of the ore changes with depth from weathered and oxidized ore to transition ore oxide and sulphide , and new processing facilities are required to effectively produce copper and cobalt from these transition ores. Both the old and .

cobalt processing Uses, Supply, and Facts Britannica

Mineral processing. The most important sulfide sources, the copper-cobalt ores of Congo Kinshasa and Zambia, are processed in the conventional manner to produce a copper-cobalt concentrate. This is then treated by flotation to separate a cobalt-rich concentrate for treatment in the cobalt circuit.

Cobalt extraction - Wikipedia

Cobalt extraction refers to the techniques used to extract cobalt from its ores and other compound ores. Several methods exist for the separation of cobalt from copper and nickel. They depend on the concentration of cobalt and the exact composition of the used ore .

cobalt production process from copper cobalt ores

Nickel and Cobalt Production - ScienceDirect No attempt was made to recover the copper. Because of unfavorable economic conditions, the mine was put on caretaker status in 1982. In 1979, the Bureau undertook laboratory research to develop a process to recover

COBALT PROCESSING DEVELOPMENTS K G Fisher Bateman Engineering Projects - SAIMM

3.2 DRC/Zambian Copper-Cobalt Ores Oxides and Sulphides Historically, most of the DRC/Zambian cobalt has been recovered from copper flotation concentrates by a Roast-Leach-Electrowin RLE process. This comprised roasting for the sulphides , sulphuric

Copper-Cobalt ores - Danafloat

Copper is separated from the cobalt in the bulk concentrate by raising the pH up to at least 11 which depresses the cobalt minerals. Cobalt depression can be enhanced by small cyanide dosages. If the cobalt is found with chalcopyrite, bulk flotation can be carried out with xanthate at pH 10, and separation made at pH 4 with an amine and combinations of fatty acid to recover the cobalt minerals.

Ores Containing Cobalt Cobalt Institute

Cobalt is almost always a by- or co-product of mining for other base metals, chiefly nickel and copper. Large quantities of cobalt also occur on the sea floor, contained within manganese nodules and cobalt-rich crusts, although they are not economically viable with current technology and economic conditions.

Production and Supply Cobalt Institute

Cobalt is only extracted alone from the Moroccan and some Canadian arsenide ores. It is normally associated as a by-product of copper or nickel mining operations. Around 55% of the world cobalt production comes from nickel ores.

Sulfatizing roasting for copper and cobalt production

126 for sulfuric acid production. This production process has been in operation for several decades. It is particularly suitable for cobalt- containing copper ores. Process control is uncompli ed and operation is profitable at low capacities. The process offers a

Nickel and Cobalt Production - ScienceDirect

While most cobalt 50% is produced as a coproduct from the processing of nickel/cobalt ores, a significant amount of cobalt 35% is produced from Central African copper–cobalt ores. The remaining 15% is produced from other primary sources, such as Moroccan cobalt–arsenic ores.
