Kinetics of bornite leaching in the presence of glycine

Improving hydrometallurgical methods for processing copper-containing sulfide natural materials is an urgent task due to the increasing environmental problems, depletion and complexity of composition processed raw materials. The kinetic regularities process extracting copper into solution from solid phase bornite by alkaline solutions glycine hydrogen peroxide are investigated. kinetics was studied at room temperature a concentration 0.1 M peroxide. varied 1.0 M. In pH range medium (8÷11), exists in form glycinate anions that react with Cu2+ ions stable (II) glycinate, which contributes effective extraction mineral solution. introduction oxidizer – system significantly increased degree first 10 minutes 29 37 %. results conducted studies allow us consider as promising solvent reagent leaching
