Improvement Technology Of Recovery Efficiency in Processing for high Purity of Crude-Zinc Oxide obtained by pryometallurgy

摘要

The present invention relates to a method for improving the recovery efficiency in a process for high purity of crude-zinc oxide obtained by pyrometallurgy, which can achieve a high recovery efficiency of 90% or more based on a zinc component by molding recovered crude-zinc oxide from various zinc-containing wastes containing electric arc furnace dust into a briquet or pellet shape and inserting the crude-zinc oxide in a kiln.
