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.
The ore is comminuted and the cobalt rich oxides are separated by froth flotation. The cobalt-bearing concentrate is then mixed with lime and coal, and then melted in a reducing atmosphere. Iron and lighter impurities float to the surface as solid dross or are expelled from the melt as gas. The remaining liquid is composed of a heavier copper smelt containing approximately 5% cobalt that is processed for its copper and a lighter slagthat is approximately 40% cobalt that is further refined by hydrometallurgical and electr
Nov 01, 2019· Sulphidisation followed by flotation is the preferred beneficiation technique for oxidised copper-cobalt ores. • The integration of CPS systems into the flotation circuits can help minimise reagent overconsumption. • Application of selective flotation can help a concentrator to produce separate oxide and sulphide concentrates.
major source of cobalt has changed whilst the world’s cobalt usage has increased steadily. Cobalt is produced mostly as a by-product of other major metal extraction processes mainly copper and nickel and in recent decades the nickel industry has been the major source of cobalt. Now however the Democratic Republic of Congo
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.
First Cobalt’s main cobalt exploration project is the Iron Creek Cobalt Project in Idaho, USA, which has an Indicated Resource of 2.2 million tonnes at 0.32% cobalt equivalent (0.26% cobalt and 0.61% copper) for 12.3 million pounds of contained cobalt and 29 million pounds of contained copper as well as an Inferred Resource of 2.7 million
Copper is produced by the conventional SX/EW process. Pilot plant trials have been successfully completed. Western Minerals Technology is paying special attention to nickel- cobalt-copper ores and copper concentrates with the impurities, which are difficult to process by pyrometallurgical processes.

Cobalt processing Cobalt processing The metal and its alloys: In the production of a so-called cemented carbide, such as tungsten carbide, a briquetted mixture of tungsten carbide and cobalt powder is heated at a temperature above the melting point of cobalt. The latter melts and binds the hard carbides, giving them the toughness and shock resistance needed to make carbides of practical

Copper is produced by the conventional SX/EW process. Pilot plant trials have been successfully completed. Western Minerals Technology is paying special attention to nickel- cobalt-copper ores and copper concentrates with the impurities, which are difficult to process by pyrometallurgical processes.
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger
