METHOD FOR PREPARING COPPER HYDROXIDE AND DEVICE USED IN THE METHOD

摘要

A method for preparing copper hydroxide by reaction of copper oxychloride or oxysulfate with sodium hydroxide, wherein the reaction is performed continuously, so that the reaction mass advances in piston-like fashion along a path. Agitation of the mass sufficient to keep it fluid is provided. The device includes a reactor formed by a plurality of units, each formed by an agitator and by a non-agitated duct. The invention allows to obtain a highly pure product at low cost.
