Nickel and Cobalt Solvay

2021-9-2  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.

Nickel Cobalt Flotation Process - 911 Metallurgist

2016-6-7  Wet, high-intensity magnetic separation (WHIMS) was considered as a potential method for removing the cobalt-nickel mineral from the chalcopyrite concentrate. In anticipation of such tests, the magnetic susceptibilities were measured on four high-grade mineral specimens--siegenite, chalcopyrite, sphalerite, and galena. The tests were made on a vibrating sample magnetometer, and the results are

"Nickel and Cobalt Production" by Michael S. Moats and ...

2014-1-1  The production of nickel and cobalt from primary sources involves beneficiation, and hydrometallurgical and pyrometallurgical processing. Nickel is recovered from lateritic oxides either as ferronickel from saprolite ores or as an intermediate mixed sulfide or hydroxides from limonite ores. Sulfide ores are converted into matte.

Nickel / cobalt mining extraction procedures

The process begins by adding the sulfide-associated mineral to a reactor with sulfuric acid and pressurised air. This procedure removes the sulphides to obtain nickel (II) sulfate and cobalt (II) sulfate in solution. In this first dissolution stage, the sulfide is removed. NiS + 2O2 NiSO4. CoS + 2O2 CoSO4.
