Title
(EN) Aqueous copper composition
Abstract
(EN)
An aqueous copper composition is provided for use in hydrometallurgical flotation processes comprising a copper component, an ammonium hydroxide component or an amine component, and a weak acid component. The composition is used as an activator in hydrometallurgical flotation processes to activate sphalerite, pyrrhotite, marrnatite, and arsenopyrite. The composition replaces copper sulphate and is added in an amount from 20 to 40% (w/w) of the standard amount of copper sulphate generally used as an activator.
