The beneficiation method of antimony ore is determined according to the ore type, mineral composition, mineral structure, and dissemination characteristics. The commonly used beneficiation methods of antimony ore are manual sorting, gravity separation, and flotation.
Manual sorting is based on the differences of color, luster, and shape between antimony bearing minerals and associated gangue, which is to select mineral by hand through human eye observation. This beneficiation method has high labor intensity, but it can get high-grade bulk antimony concentrate.
Gravity separation is suitable for antimony ore with coarse particle size. The most commonly used gravity separation equipment is mineral jig machines, and sometimes shaker. For antimony ore with very fine disseminated particle size, the gravity separation method can be used for pre-concentration, and then the flotation method is used for cleaning after ore grade is improved.

Flotation is an important method for antimony ore dressing. Antimony sulfide ore is easy to float, and good beneficiation indexes can be obtained by flotation. Antimony oxide is difficult to float, and it is generally recovered by gravity separation. Although eduction floatation can effectively process antimony oxide ore, due to the complex beneficiation process and huge investment in equipment, it is rarely used in the field of antimony oxide ore flotation and has not been widely promoted and applied. Gravity separation the most ideal method for antimony oxide ore dressing.

Antimony ore beneficiation production line： For antimony sulfide ore, the combined process of manual sorting–gravity separation–flotation can be used to recover bulk antimony concentrate, granular antimony concentrate, and powder antimony concentrate respectively. For antimony oxide ore processing, the gravity separation method can be used for recovery. The flotation–gravity separation process can be used to recover sulfide oxide mixed antimony ore.
