    Hydrogen reduction of nickel and cobalt was developed by the Chemical Construction Company as an alternative to electrowinning for the production of nickel and cobalt metals. [Sherritt obtained the technology, which was subsequently used in the Fort Saskatchewan operation.] ... (PGM) concentrate for refining.

  • Cobalt processing | Britannica

    From copper and nickel processing. In nickel smelting, most of the cobalt is recovered during electrolytic refining of the nickel by precipitation from solution, usually as a cobaltic hydroxide. But even in nickel smelting, cobalt starts to oxidize before the nickel and can be recovered from the final converter slag.

    Alumina concentrate, produced after roasting and leaching the spent catalysts, is mixed with a reductant and melted in the EAF to produce a mixed metallic alloy containing 37–43% nickel and 12–17% cobalt, which is finally sold to nickel and cobalt refineries.

    Cobalt. Super alloys containing cobalt have been used in the production of jet engines and gas turbine engines for energy generation. These super alloys make up nearly half of the cobalt used each year. Cobalt is also used in making of cutting and wear-resistant materials. Cobalt's use in rechargeable batteries is one of its fastest growing...

    Then, solvent extraction is used to separate the cobalt and nickel, with the final nickel concentration greater than 99%. Electrorefining A second common form of further refining involves the leaching of the metal matte into a nickel salt solution, followed by the electro-winning of the nickel from solution by plating it onto a cathode as electrolytic nickel.

    Cobalt refining often takes place outside of the country where the ore or cobalt concentrate is initially produced. In 2010, the countries producing the largest amounts of refined cobalt were China (33,000 tons), Finland (9,300) and Zambia (5,000).
