The Extraction Behaviour of Zinc, Lead and Silver from Ores and Concentrates by Glycine Leaching Processes

Abstract

This research covers the fundamental aspects of the direct leaching of sphalerite by considering the dissolution of silver, lead, and copper contents and their effects on the process. The effects of independence variables such as sodium hydroxide, potassium permanganate, hydrogen peroxide, lead nitrate, sodium chloride, dissolved oxygen, temperature, glycine concentration, dissolution time, and particle size on the process were investigated. All the outputs have been modelled and optimised through the analysis of variance.
