ABSTRACT:
In a process of producing copper(I) oxide by the action of an aqueous solution of a mineral acid and of oxygen-containing gas on small-lump copper metal with continuous agitation, a temperature from 10.degree. to 40.degree. C., preferably from 15.degree. to 35.degree. C., is maintained to effect a formation of particulate yellow copper(I) oxide (Cu.sub.2 O). An organic acid of the group consisting of formic acid, acetic acid, ascorbic acid, preferably ascorbic acid, may be used in addition to the mineral acid.
