Abstract

Inventia se refera la un procedeu de recuperare a seleniului continut în gazele sulfuroase provenite din pirometalurgia cuprului, realizeaza separarea selectiva a unui namol plumbo-selenios care se supune lesierii alcaline în autoclave în conditii cunoscute.The invention relates to a process for recovering the selenium contained in the sulphurous gases from copper pyrometallurgy, selectively separates a plumb-selenium sludge which undergoes alkaline leaching in autoclaves under known conditions.
