Norilsk Nickel has created a new nickel production technology
Specialists of the Department of Scientific and Technological Development and Environmental Safety of Kola MMC (MMC Norilsk Nickel’s subsidiary) together with the specialists of Gipronickel Institute invented a new technology of nickel production from sulphide ore.
The technology is based on leaching process with supply of oxygen and chlorine. Iron contained in the raw material goes to waste and copper in the form of a sulphide product is removed from nickel and cobalt containing leaching solution, which is then cleaned from other impurities. In Electrolysis Shop refined nickel and cobalt hydroxides are processed to produce commercial metals.
