A Review on Novel Techniques for Chalcopyrite Ore Processing

Chalcopyrite ores are usually processed by means of hydrometallurgical or pyrometallurgical processes, but due to environmental aspects and the possibility of increased exploitation of mixed and lower grade ores and relatively small isolated deposits, there has been a worldwide upsurge of interest in the hydrometallurgical processes of this ore as compared to pyrometallurgy.

GRAVITY LEACHING – THE ACACIA REACTOR

Basic flow sheet of the ACACIA Reactor The ACACIA Reactor relies on a simple flow sheet, with a design that incorporates few moving parts. Due to the simple design of the unit it will allow easy integration into a gold room, and the use of site standard components. The basic flow sheet is simple and involves 8 major process steps. 1.
