Separation of Co and Ni from a chloride leach solutions of laterite ore
In order to separate Ni(II) and Co(II) from the chloride leaching solution of nickel laterite ore, solvent extraction experiments with the mixtures of organophosphorus extractants and LIX63 were performed in the pH range from 1 to 3. Among the studied mixtures, a mixture of D2EHPA and LIX63 with the molar ratio of 3:7 showed the best …

Nickel / cobalt mining extraction procedures
The ore is mixed with calcium oxide and silica, producing a slag. This makes it possible to separate silver, a mixture of materials rich in copper, nickel and cobalt and a scorifiable residue. This mixture rich in copper, nickel and cobalt is what is technically called "speiss". Getting from this mixture to the pure metal is a complex process.

Extraction and Refining of the Platinum Metals
The dissolving of the nickel anodes follows the same general pattern, the products being pure nickel cathodes and an anode slime containing the bulk of the platinum group metals. In this case the electrolyte is a neutral solution of nickel sulphate containing boric acid as a buffer and has to be continually purified to produce a pure cathode.
