Bioleaching of copper ore flotation concentrates

The main objective of this work was to evaluate a bioleaching process from the treatment of two concentrates, (i) a copper gold bearing concentrate and (ii) an ordinary copper flotation concentrate, using mesophilic bacteria. The special gold-bearing copper flotation concentrate

Project

The goal of flotation testing was to concentrate the sulfides and the gold in the metallurgical sample into a concentrate for pre-treatment and cyanidation. The results indicate that the material can easily be floated to produce a pyrite-pyrrhotite-arsenopyrite gold concentrate. Results of the small scale batch flotation test are as follows:

The ground ore is then floated to produce a gold rich copper concentrate for filtration and sale to overseas smelters. Flotation tailings are then leached for further gold recovery. The ore processing rate is approximately 35 million tonnes per annum. Typical head grade is approximately 0.8 gram per tonne gold and 0.11 per cent copper.

The flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation.
