Abstract

The invention relates to the technical field of hydrometallurgy, in particular to a method for deironing through nickel-containing leaching liquid comprehensive treatment. Magnetic field electrolysisis carried out, the magnetic field intensity is controlled to be 7-9 A / m, deironing is achieved while nickel electrolysis is carried out, the nickel electrolysis of nickel electrolysis is shortened, and the deironing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of hydrometallurgy, in particular to a method for comprehensively treating nickel-containing leachate and removing iron. Background technique [0002] In the process of hydrometallurgy, acidic solution is often used to leach ore, and iron in minerals often enters the solution in the form of trivalent or divalent ions. Iron removal is the most common and important process in hydrometallurgy due to the great hazards of iron in subsequent processes such as electrodeposition. In order to deposit iron from solutions with high iron content, since the end of the 1960s, jarosite method, goethite method, etc. have been applied in industry successively as new iron precipitation methods. When the nickel-containing leaching solution is used to electrolyze the anolyte and hydrolyze the high-nickel iron slag produced by iron removal, it is usually treated by sulfuric acid dissolution and leaching, sodium chlorate oxidati...
