LEACHING METHOD OF NI FROM THE LOW FINENESS ORE

摘要

Extraction of nickel from the low quality laterite ore is effected by leaching electrochemically in the electrolysis bath with a separator between cathod chamber and anode chamber. Nickel is recovered from 0.01-10.0 mol. sulfuric acid solution with blowing the sulfurous acid gas. Also anode chamber consists of 0.01-10.0 mol. sulfuric acid solution including source ore powder under 10 mesh.
