HYDROMETALLURGICAL PROCESS FOR PRODUCING FINELY DIVIDED COPPER AND COPPER ALLOY POWDERS

摘要

ABSTRACTA process for producing finely divided spherical coppercopper alloy powders comprises forming an aqueous solution ofcopper and alternatively other metal values forming areducible metallic material from the solution, reducing thematerial to metal powder particles, subjecting the metalparticles to a high temperature zone to melt a portion of themetal powder particles and to form droplets and cooling thedroplets to form an essential spherical metal alloy particles.
