Antimony ore mention is the use of hand-selected antimony ore and gangue minerals color, luster, shape differences in the conduct of this beneficiation method is relatively primitive, labor-intensive, but can output high-quality chunk of antimony ore concentrate , can reduce processing costs and energy consumption. Hand-selected antimony ore is generally done in hand-selected equipment on the belt, there are many within the pit or mine mouth completed.
For most of the re-election of antimony ore processing are applicable, because a large part of the antimony mineral density, coarse mineral and gangue ease separation method with re-election. In short, whether it is a single antimony sulfide ore or sulphide - mixed oxide antimony ore, have better conditions for re-election. And low cost of re-election, but also in the coarse particle size range of selected coarse concentrate a large number of qualified, discard large quantities of waste rock, thus re-election law who are still willing antimony ore beneficiation methods used. Antimony ore re-election equipment mainly refers to jigger sometimes used shaker.
Flotation is the most important election of antimony ore beneficiation methods, antimony sulfide minerals are easy to float minerals, mostly using the flotation method to improve the ore grade. Where: stibnite often do first with lead salt activator, is also useful for copper or copper salt and lead salts used, then flotation collector. Common collector of butyl xanthate or shale oil and diethyldithiocarbamate mixture of pine oil frother or the 2nd oil; antimony oxide ore is difficult to float the ore, the main use of the re-election sorting method.
