Antimony Smelting Mineral Processing & Metallurgy

China now leads the world in antimony production, having contributed during recent years something over 60 per cent, of the world’s production. The history of the antimony industry of China dates back to 1897 when the Tai Shing Co. was formed, under contract with the Hunan Bureau of Mines, for the smelting of the ore to crude; and in 1908 the Wah Chang Mining & Smelting Co. was formed for

MIT’s accidental smelting discovery unlocks the potential

In a typical smelting process, this sulphur would have immediately bonded with oxygen in the air to form sulphur dioxide, the major cause of acid rain. Antimony captures electronic niche markets. What the effect of this discovery will be on the global antimony market is hard to guess. Antimony, together with others such as cobalt, gallium, germanium, zirconium, rhenium, titanium, tungsten and the rare earth metals, is classed as a ‘minor’ metal, and world antimony

01/07/2014· More specifically, pelletized antimony concentrates combined with coal are placed into a blast furnace, being smelted at 1300–1400°C in an oxidization environment. The resulting antimony oxide products are volatilized and collected by a bag-type dust collector, which are subsequently placed into a reverberatory furnace for additional refinement. WQS is produced when the remaining

Worker Health Study Summaries Antimony Smelters

Exposure to Antimony. The Occupational Safety and Health Administration’s (OSHA) standard for antimony is 0.5 mg/cubic meter averaged over 8 hrs. In 1975 and 1976, some smelter workers were exposed to levels higher than this. The current owner of the smelter, reports that the levels now are lower. Since 1984, the owner reports that the smelter has used a voluntary limit of 0.2 mg/cubic meter. In addition, they report no smelting since 1991. If you still work at a smelter,

The metallurgy of antimony ScienceDirect

17/07/2012· Antimony metal, also known as ‘regulus’, melts at 630 °C and boils at 1380 °C. Antimony and the natural sulfide of antimony were known as early as 4000 BC. It was used as a coating for copper between 2500 BC and 2200 BC. The sulfide was used as eyebrow paint in early biblical times, and a vase found at Tello, Chaldea, was reported to be cast antimony. Antimony is seldom found in nature

Antimony potassium tartrate (UK PID)

These changes developed after at least ten years working in an antimony smelting plant where the dust contained nearly 90 per cent antimony trioxide with some antimony pentoxide and small amounts (up to five per cent) of silica (Potkonjak and Pavlovich, 1983). Cough (in 31 of 51 subjects) and exertional breathlessness (in 26 cases) were the symptoms most frequently reported with wheeze, chest pain,

Viscosity Property of Gold-Antimony Smelting Slags by

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.

Antimony Wikipedia

Antimony is a chemical element with the symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name kohl. Metallic antimony was also known, but it was
