Analysis of Adsorption of Phytogenous Collecting Agents at the Gold-Containing Sulfides during Flotation

摘要

The article presents research findings of testing adsorption of phytogenous collecting agents at the surface of gold-containing pyrite and arsenopyrite using UV spectroscopy, as well as analytical scanning electron, laser and atomic force microscopy methods. It is found that components of extracts of oak bark and umbelliferous plant foliage are selectively adsorbed at the sulfide mineral surface, which enables selective flotation of pyrite and arsenopyrite in gold-bearing sulfide ore dressing.
