Antimony Roasting Plant

Roasting Arsenic & Antimony Ores

Roasting before Fusion & Assay. Ores containing large quantities of sulphur, arsenic, or antimony may sometimes be roasted with advantage as a preliminary to fusion. Roasting is effected in shallow circular clay dishes, in a muffle, or in the crucibles in which the fusion is afterwards performed.

Oxidizing Roast; Stibnite the Antimony Mineral

The leading antimony mineral is stibnite. In smelting stibnite ore two processes are available, precipitation and roasting-reduction. The former is suited, only for high-grade ores. As low-grade ores are more common than high-grade, roasting-reduction is of greater importance than precipitation.

Oman antimony roasting project readying for June production

The plant is due to produce its first antimony metal in June, with the ramp-up to a rate of between 2 000 t/m to 3 000 t/m expected by the end of 2018. Once in full production, the OAR would produce up to 50 000 dry tonnes a year of antimony and gold concentrate,...

The goals of the roasting process are: High sulfur and carbon burn-out. High arsenic removal and/or fixation. Uniform and precise temperature control. Precise control of oxygen. Safe and controlled combustion of additional fuel when required. High throughput per roaster …

Antimony Assay & Determination by Roasting Stibnite

Antimony Assay & Determination by Roasting Stibnite. The product obtained by roasting stibnite is likely to contain some unoxidized antimony trisulphide and a mixture of antimony trioxide and antimony tetroxide. It was desired to determine, as accurately as possible, the condition of the antimony as well as the total quantity present.

Antimony Smelting - Mineral Processing & Metallurgy

The ideal ore for treatment in such furnaces is one containing antimony from 15 to 25 per cent.; ore above 40 per cent. Sb would partly volatilize and partly liquate, and part of the liquated product would combine with the volatilized trioxide to form an oxysulfide compound, commonly known as antimony glass…

Antimony - Wikipedia

Antimony is a stone 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.

In terms of developing end products, antimony derivatives offer the potential for further margin growth over and above the normal conversion margin. TECHNOLOGY: The Project applies a proprietary antimony and gold roasting technology that is flexible and sophisticated enough to be able to process many types of grade and impurities.

A Brief History of Antimony in China | Amspec

Shortly thereafter, Wah Chang constructed an antimony smelter in Changsha to produce antimony metal using low grade antimony ore. This smelter became one of 24 roasting furnaces and 19 reverberatory furnaces that made up Wah Change’s first plant. This plant is viewed as the start of large scale antimony production in China.

Removal of Antimony from Aqueous Systems

antimony. Andreae and co-workers (10) reported substantial inputs of arsenic and antimony into an estuary in Portugal from a pyrite roasting plant. Ndiokwere and Guinn (11) noted the presence of elevated concentrations of toxic metals, including antimony, in Nigerian rivers and harbors in 1983 as a result of industrial pollution.
