different concentrates obtained are of poor quality with a low rate of metal recovery. This makes further pyrometallurgical processing of these ores difficult and costly (Rubio and Frutos, 2002) and renders them unattractive for commercialization (Sandstrisom and Petersson, 1997). As a result, metal value is preferably extracted from sulphide ores through hydrometallurgical processes ...
