The effect of flotation collectors on the electrochemical

2019-1-1  1. Introduction. Gold occurs among a large variety of minerals (Harris, 1990), mostly in its zero-valent native metallic form but also as gold metal alloys (Chryssoulis and Cabri, 1990, Dunne, 2016).Gold particles in an ore deposit may vary in size from large nuggets to tiny particles enclaved within sulfide minerals, in particular associated with pyrite, containing trace to minor

Gold Extraction from a High Carbon Low-Grade Refractory

A high carbon low-grade gold ore, in which gold mainly occurs in carbonaceous matters, is a typical refractory gold ore whose conventional cyanide leaching extraction is only 12.9 %. In this paper, by the process of flotation-roasting-leaching, gold was effectively enriched and extracted.
