The role of sodium sulfide in the flotation of pyrite

In copper gold flotation plants, pyrite which is depressed in copper flotation is often floated subsequently with the addition of sodium sulfide (Na 2 S) to recover the associated gold. For the first time, this study investigated the role of Na 2 S responsible for the flotation of pyrite depressed in chalcopyrite flotation through flotation tests and Cyro XPS (X ray photoelectron spectroscopy

Innovations Introduction to Copper Mining amp; Extraction

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
