Nickel and Cobalt Solvay

1 天前  CYANEX® 272 extractant has proven to be the reagent of choice for the separation of cobalt from nickel from both sulfate and chloride media. It is used to produce a major portion of the world's cobalt. Since the active component of CYANEX 272 extractant is a phosphinic acid, metals are extracted through a cation exchange mechanism.

Refractory Challenges in Nickel and Cobalt Processing

2021-2-18  In addition to post-mortem studies, thermochemical calculations and corrosion testing provide better understanding of the wear mechanisms. Based on such research results, combined with specific process knowledge, appropriate brick lining solutions for nickel and cobalt processing furnaces can be recommend.

A New Process for Cobalt Nickel Separation

2015-11-20  3.1 Basic Process for Cobalt Separation from Nickel CSIRO have developed a number of solvent extraction processes to separate nickel and cobalt (together) from other elements present in solution such as zinc and manganese. This technology uses a synergistic combination of two or more extractants, and is thus known as SSX.

COBALT PROCESSING DEVELOPMENTS K G Fisher

2011-7-5  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.

Processing of nickel- and cobalt-containing leach liquors

Abstract Acidic as well as ammoniacal leach liquors obtained from three different raw materials, namely, lateritic nickel ores, copper converter slag and Indian Ocean manganese nodules, were treated for removal of impurities and separation of copper, nickel and cobalt. Precipitation and solvent extraction techniques were used for these purposes.
