Abstract

The invention relates to a preparation method of high-purity active plating grade copper oxide powder. The preparation method comprises the following steps: firstly preparing copper sulfate solution and alkali solution of sodium hydroxide or potassium hydroxide, then respectively introducing the copper sulfate solution and the alkali solution into a reactor through a first pressurized spray system and a second pressurized spray system for mixing, and adding raw materials to the reactor according to a proportion which enables the pH value of a mixed material to be between 8 and 12; after material addition is stopped, carrying out stirring reaction on the mixed material at 40-100 DEG C for 30-60 minutes, then carrying out pressure filtration on a reacted material, and washing to be neutral to obtain a reaction product filter cake; then drying, calcining and screening the reaction product filter cake to prepare the copper oxide powder. The copper oxide prepared through the preparation method disclosed by the invention is uniform in granularity, high in bulk ratio and low in impurity content.
