Recovery of cobalt, nickel, and copper from slags, using ...
The alloy produced in the reduction process can be leached with spent electrolyte from a copper or nickel electrowinning process. Mintek has developed a leaching process that solubilizes the nickel, copper, and cobalt, while rejecting the iron and any sulphur into the solid residue (by decreasing the pH appropriately).

NICKEL, COPPER AND COBALT DISTRIBUTION AND
2015-9-7 (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 - an overview ScienceDirect Topics
Industrial grade pyrometallurgy is usually direct put the WPCBs containing 5%–40% copper into the blast furnace, and the product is black copper containing 70%–85% copper. The black copper is then poured into the converter, which makes an oxidizing slag of Pb, Zn, and Sn, and the copper that contains 95% copper content.

Pyrometallurgical Process - an overview ScienceDirect
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 anodic Cu production in a furnace (99.5% Cu).

Review of copper pyrometallurgical practice: today and ...
Abstract. The pyrometallurgical processing of copper varies worldwide with respect to the charge materials, process, operating parameters, and the physical shape, size, and orientation of the vessel. Plant operations may be either batch, semi-continuous, or fully continuous to produce blister copper or other end product.

COBALT PROCESSING DEVELOPMENTS K G Fisher
2011-7-5 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.

Hydrometallurgical Process to Recover Cobalt from Spent
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 ...
