10. REFINING: 1.MOND PROCESS The purest metal is obtained from nickel oxide by the Mond process, which achieves a purity of greater than 99.99%. This process has three steps: 1. Nickel oxide reacts with Syngas at 200 °C to give nickel, together with impurities including iron and cobalt.
Metal values may be recovered from metal bearing sources in a hydrometallurgical process in which a metal bearing source such as an ore and the like is reduced with a reductive roast only or with the presence of at least one additive at temperatures ranging from about 500° to about 900° C. Thereafter the reduced source is subjected to a leach in the presence of a basic leaching agent to ...

The occurrence of cobalt with copper and nickel and the propensity for this material to report mainly to the final-process discard slag has provided a substantial resource in both current arisings and stockpiles in many copper and nickel smelting operations. Ausmelt has undertaken investigations for the recovery of cobalt from smelter slags using top-submerged lancing technology. These tests ...
Answer (1 of 2): Primary nickel and cobalt are extracted from two different types of ores: sulfide ores and oxide ores. The extraction methods are typically based on pyrometallurgy, hydrometallurgy, and electrometallurgy principles that yield different products bearing nickel and cobalt. Pyromet...
Hydrometallurgical battery recycling in action. In the illustrative flow diagram below, value metals such as cobalt, nickel and lithium are recovered from a black mass leached liquor (pregnant leach solution, or PLS) using a series of solvent extraction circuits. After extraction and removal of nickel from the solution, CYANEX 936P® can be ...

The work presents studies on the application of hydrometallurgical recovery of cobalt(II) from solutions after leaching spent industrial catalysts used in process of hydrodesulfurization. A four-stage process was proposed, which consists of: leaching, precipitation of metal hydroxides accompanying Co(II), extraction of Co(II) with bis(2,4,4-trimethylpentyl)phosphinic acid and Co(II) stripping ...
Cobalt (Co) is a transition metal featuring unique physical properties which makes its use critical for many high-. tech applications such as high strength materials, magnets and most importantly ...
Three main processes for cobalt extraction can be distinguished: a) hydrometallurgy, b) pyrometallurgy and, to a lesser extent, c) vapometallurgy. The processes involved and flowsheets employed depend on the ore mineralogy and are usually unique to the ore deposit type and even the ore type. 5.1. Overview.
Pyrometallurgy is widely used for the commercial recovery of Co. The commonly used treatment of spent LIBs is similar to the ore smelting (Dunn et al., 2012). Before the smelting process, the modular LIBs are first disassembled into separate cells and then fed into a heating furnace.
