- The state of technology for separation of antimony minerals is reviewed and experience from processing plants is summarized. The high density of antimony minerals and their tendency to grind to slime (hardness of 2.5 on Mohs' scale) make gravity separation in the mill circuit an interesting possibility for the first step in the process. Marketing considerations make separation of arsenopyrite an important part of the process in some cases. The design of flotation circuits for beneficiation of stibnite is usually very straightforward: rougher, scavenger and two-stage cleaner flotation are usually enough to produce concentrates grading better than 60% Sb. The choice of methods for depressing antimony minerals in complex sulphide ores depends on what kind of mineral is the predominant impurity. It ought to be possible to depress ferrous antimony minerals effectively in pyrite-selective environments
