A process to carry this out, using a DC arc furnace, has been under development at Mintek since 1988, and has successfully been demonstrated at pilot scale 1. The process involves the selective carbothermic reduction of the oxides of cobalt, nickel, and copper, while retaining the maximum possible quantity of iron as oxide in the slag.

pyrometallurgy, extraction and purification of metals by processes involving the application of heat.The most important operations are roasting, smelting, and refining.Roasting, or heating in air without fusion, transforms sulfide ores into oxides, the sulfur escaping as sulfur dioxide, a gas.Smelting (q.v.) is the process used in blast furnaces to reduce iron ores.

(nickel, copper and cobalt) are recovered as part of the platinum-producing process. The metals are mined from the Bushveld Complex, mainly as sulphide minerals contained in the platinum ores – the Merensky reef, the Platreef and the UG-2 chromitite reef. After mining, the base metals pass through the concentrating, smelting and converting ...

Pyrometallurgy Basic Principle. The basic premise of most pyrometallurgical operations is simple: high-temperature chemistry is employed to segregate valuable metals in one phase while rejecting gangue and impurities in another phase. In most instances, both phases are molten (such as the matte and slag in a conventional copper smelting operation).

The next step is the converting process in the Cu converter by blowing hot air from tuyeres in order to obtain molten Cu matte (Cu–Fe–S) (35%–70% Cu). This step oxidizes iron sulfide and converts copper sulfide to metallic blister Cu (about 98.5% Cu). The last step is …

The copper flotation step is inherently inefficient for cobalt, with recoveries typically from 40% for oxides up to 80% for sulphides, so there is a substantial amount of cobalt contained in tailings dams that could be recovered – e.g. the Kolwezi Tailings Project.

Recovery from copper-cobalt sulfide concentrates. The ores are treated by a sulfatizing roast in a fluidized bed furnace to convert copper and cobalt sulfides into soluble sulfates and iron into insoluble hematite.The calcine is subsequently leached with sulfuric acid from the spent copper recovery electrolyte.Oxide concentrates are introduced at this leaching step to maintain the acid balance ...

Copper hydrometallurgy is a branch of metallurgy method to extract copper directly from those difficult-to-concentrate copper oxide ore. Traditional copper hydrometallurgy process typically consists of atmospheric leaching, solvent extraction (SX) and electro-winning (EW). It can produce either copper cathode or copper sulphate crystal.

Pyrometallurgy process of lithium battery recycling refers to the following steps: The battery shell is peeled and the contents in treated by reduction smelting to get copper-nickel-cobalt alloy, and aluminum and lithium are lost in smelting dross. The copper-nickel-cobalt alloy is processed by solvent extraction to produce metal salts or pure ...

As presented in Table 1, the Umicore process is based on the hydrometallurgical treatment of the cobalt, nickel, manganese, copper and iron alloy resulting from the pyrometallurgy step, in order to separate cobalt from nickel, to recover them selectively in order to use them as battery electrode precursor . Thus, cobalt is recovered as an oxide ...

Acid leach liquors from spent lithium-ion batteries that use lithium cobalt dioxide (LiCoO 2) as a cathode active material contain valuable metals such as cobalt and lithium, as well as common metals such as aluminum and copper.The objective of this study was to develop a hydrometallurgical process that provides a degree of high selectivity between aluminum, cobalt, copper, and lithium …

Unfortunately, extraction of copper from sulphidic ores, either by pyrometallurgy or hydrometallurgy, is typically associated with a relatively large eco-footprint, in terms of energy requirements, CO 2 emissions and/or the use of chemical reagents.

Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4
