Antimony Gravity Concentration

milling, flotation, and gravity concentration [1]. These steps are usually carried out close to the mining site, and result in Sb-containing mine tailings. Depending on the grade of antimony in the concentrate, different pyromet-allurgical methods can be used to extract antimony [1]. For low-grade ores (5–25 % Sb), oxide volatilization is used.

Uses: A very minor ore of antimony and as mineral specimens. Antimony does not often form in its elemental state and is far more common in sulfides and sulfosalts such as stibnite, tetrahedrite, bournonite, boulangerite and jamesonite .

Pilot scale gravity concentration tests have shown that free gold as coarse as 0.84 mm (20 mesh) occurs in the ore, closely associated with sulfide mineralization. Microscopic analysis of gravity concentrates has shown abundant hexagonal arsenopyrite grains and numerous blades of stibnite with lesser amounts of antimony oxides and scheelite.

Hence, finding a pre-concentration device that can efficiently discard gangue minerals before shaking table, will significantly save the cost in dealing with tailings of antimony oxide.

Antimony Production. Based on production volume, in 2018 almost 70% of antimony was mined as by- or co-product, indicating a high supply risk 2. Antimony is typically a by-product of gold mining, as is the case for Russian gold producer Polyus and their Olympiada mine 3, which is the world's largest antimony mine.

The gravity separations are simple and separate mineral particles of different specific gravity. As the density of gold mineral is much bigger than gangue mineral, for the gold mine which has gold particles people often use the gravity separation process. Gravity concentration is a proven process for mineral beneficiation.
