If antimony ore contains more than 90% stibnite, it can be sold directly for producing antimony compounds or conversion to antimony metal (Herbst . et al., 1985). Crude materials marketed for the manufacturing of pure antimony products (mostly oxide) consist of antimony sulfide concentrate and lump antimony sulfide ore (USGS, 2001). 4

Estimates of the abundance of antimony in the Earth's crust range from 0.2 to 0.5 parts per million. Antimony is chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver. Over a hundred minerals of antimony are found in nature. Stibnite (Sb 2 S 3) is the predominant ore mineral of antimony. The most important use of ...

Little or no antimony is mined in the United States. Antimony ore and impure metals are brought into this country from other countries for processing. Small amounts of antimony are also released into the environment by incinerators and coal-burning power plants. The antimony that comes out of the smoke stacks of these plants is attached to very

In this paper, the viscosities of gold-antimony ore smelting slags of different composition have been studied by the rotating cylinder method. The results showed that, for a slag of 38.95% SiO 2, 16.17% CaO, 25.97% FeO, 10.25% Al 2 O 3, 5.17% MgO, the viscosity can be decreased by reducing 3.24%–8.5% SiO 2 or increasing 3.31%–9.56% CaO content.

The ore bodies mainly occur in lamellar, quasi-lamellar and lenticular forms in the altered rocks, and are strictly controlled by anticline structure. In terms of space, elemental paragenesis-separation takes place between gold and antimony deposits, i.e. the gold deposit has antimony ore spots, and the antimony deposit has gold ore spots.
