gravity concentration is adopted for coarse-grained ores while froth flotation is preferred for finely disseminated ores. Sometime, gravity methods are applied for pre-concentration followed by flotation. The antimony content of either the ore or the concentrate determines the method of treatment for the recovery of metal. Ore orThe major concentration methods that may be applied to upgrade lower-grade lump iron ores include magnetic separation, wet and dry heavy media separation, and air-pulsed jigging.

The grades were high, normally above 5% Sb. The ore with grades 1%–2% Sb was considered low-grade, 5%–25% Sb was the average grade and ores with 45%–60% Sb were high-grade. The ore processing involved primary and secondary crushing followed by manual choice and roasting. Later, gravity concentration by shaking antimony ore and grown in a mineral medium containing antimony trioxide, oxidized the trioxide at rates of 45.5-51.6 mg/month for senarmonite (cubic) and 13.5-19.3 mg/month for valentinite (rhombic).

Antimony is a silverly, lustrous grey metal that exhibits poor heat and electrical conductivity. It is relatively soft, measuring only 3.25 on Moh's scale of mineral hardness. Known as "stibium" in classical Latin, antimony is represented by the chemical symbol Sb. A member of the arsenic group of elements, antimony is commonly found inAbstract and Figures.

fi re assaying, gravity concentration, and ore microscopy are just as important as advanced microbeam techniques. Fire assaying is the traditional method of gold analysis and is an integral element in many parts of a typical gold process mineralogical study, as it provides bulk gold balance information, complement-ing the mineralogical In nature, antimony usually exists in the form of sulfide ore or sulfosalt with copper, lead and silver (Anderson, 2019).

1. Antimony general aspects. Antimony comes under group 15 of the periodic table with ground state electronic configuration [Kr]4d 10 5s 2 5p 3. 121 Sb (57.21% abundance) and 123 Sb (42.7% abundance) are the two stable isotopes of antimony. Antimony can possess different oxidation states (such as +5, +3, 0, −3 and −5), but 3. Antimony in environment3.1. Occurrence forms of antimony. Antimony is located in the VA group of the 5th period of the periodic table of elements, and there are four valence states (Sb(-III), Sb(0), Sb(III) and Sb(V)) (Filella et al., 2002a).In the surface environment and biological media, antimony usually exists in the form of Sb(III) and A review of the environmental chemical behavior, detection and

Antimony has been known and used since ancient times, but its applications have increased significantly during the last two centuries. Aside from its few medical applications, it also has industrial applications, acting as a flame retardant and a catalyst. Geologically, native antimony is rare, and it is mostly found in sulfide ores. The Gravity methods of concentration yielded only partial separation of cinnabar and stibnite. A sample of the ore was ground to approximately 65-mesh with sodium cyanide to depress pyrite; a cinnabar-stibnite bulk concentrate was floated with a higher xan-thate collector. Lead acetate was used as an activator, and an alcohol frother SELECTIVE EXTRACTION OF MERCURY AND ANTIMONY

Gravity concentration usually is effected in water or, less often, in a heavy-liquid medium and is based on differences in specific gravity of the ore and the gangue minerals.
