copper and cobalt production process

Cobalt is widely scattered in the earth’s crust and is found in a variety of different ores in several countries. 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

  • Sep 26, 2019 Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw, mined state into a purified form for use in many industries. Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper.

  • 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 (DRC) copper-cobalt production is coming to the fore once again after a 20-year period of decline.

  • Aug 01, 2019 As cobalt is produced as a by-product of copper and nickel, countries which produce a high quantity of those two metals also produce a high quantity of cobalt. The top ten producers of cobalt in the world are identified by the US geological survey of 2017 and are listed below in Table 2. Table 2. Global producers of cobalt (Ober, 2017).

  • Recovery of Cobalt and Copper from Nchanga Mines . 0.4% copper and 0.2% cobalt which is normally discarded. The reductant used in these two processes is coke. The CRF process is intended to maximize the recovery of copper and cobalt metallic alloy through strict process control to leave minimum amounts of copper and cobalt in slag.

  • 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.

  • The Sherritt process is a hydrometallurgical process named for Sherritt Gordon Mines Ltd. (now Sherritt International) of Sherridon and Lynn Lake Manitoba Canada, based on the older Forward process developed by Dr. Frank Forward for the recovery of copper and nickel from those same mines. Nickel sulfide concentrates can be treated by either roasting or flash smelting to produce matte from which nickel and cobalt can be recovered hydrometallurgically, or they may be treated by an ammoniasolution press

  • From copper and nickel processing Cobalt contained in and smelted with copper concentrate is oxidized along with iron during the final conversion to blister copper. It then enters the slag layer, which can be treated separately, usually in an electric furnace, and the cobalt recovered by reduction with carbon to a copper-iron-cobalt alloy.
