Description

This unit process represents the production/service of 1kg of electric cobalt, MCLE process ,in Japan created from statistical information and other sources.
The system boundary of this process is "(raw material) -> hydrometallurgy/electrolysis -> (cobalt)."

Technology

Process for producing chlorine leaching-electrowinning method (MCLE method*) using nickel matte and nickel-cobalt mixed sulfide as raw materials.This process is developed by Sumitomo Metal Mining, and performed only in Niihama smelter.After raw materials (mixed sulfide and matte) go through cementation leaching - chlorine leaching and through cleaning solution, electrowinning.Separate the Co grounds in cleaning liquid phase, and separate Co and Ni by solvent extraction.Liquid containing Ni is returned to the electrolytic nickel.*MCLE method:Matte Chlorine Leach Electrowinning
