Antimony is extracted mainly from ores containing antimony trisulphide in the form of stibnite. Rich ores are first subjected to liquation, whereby the fusible sulphide is removed from the gangue and concentrated. The concentrate is then reduced to metal by smelting with wrought iron in pots, in reverberatory furnaces or sometimes in blast ...
METALLURGY. LIQUATION: Liquation is the melting of stibnite into "crudum" or "needle antimony". It is carried out between 550 and 600 degrees C. If the temperature is lower, the recovery is poor. If the temperature is any higher, the stibnite volatilizes into oxide. This method is .
antimony is one of a few elements that expand as they freeze. Antimony is a poor conductor of electricity and heat, and can be toxic in some cases, but less so in solid form. More than 100 mineral species of antimony are known; however, it most commonly combines with sulfur to form antimony sulfide or "stibnite" (Sb 2S 3).

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.

A typical stibnite deposit may contain the antimony sulfide along with pyrite and a gangue consisting of quartz, calcite, barite, kaolin and gypsum. The ore grading about 2.7% Sb is put to a combined treatment by hand-sorting, heavy medium separation and flotation ( Xikuangshan, 1964, Chen, 1964, Huang et al., 1965, Xikuangshan, 1979 ).
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.
antimony concentration process thailand - Sep 26, 2018 · Antimony is a chemical element with symbol Sb (from Latin: stibium) and atomic number 51. The industrial methods for refining antimony are roasting and reduction with carbon or direct reduction of stibnite with iron. An emerging application is the use of antimony in microelectronics. ..
Nov 23, 2010· The main purpose of this study is to characterize and separate antimony from a stibnite concentrate through a low-temperature sulfur-fixing smelting .
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.

The invention discloses a production method of continuous antimony smelting by bottom blowing bath smelting of stibnite and a device thereof. The method comprises the steps that: stibnite, iron ore, stone and anthracite, which are taken as raw materials, are weighed and then smelted and reacted in a bottom blowing oxidization smelting furnace to generate fume and melts; the melts are settled ...
Stibnite, sometimes called antimonite, is a sulfide mineral with the formula Sb 2 S 3.This soft grey material crystallizes in an orthorhombic space group. It is the most important source for the metalloid antimony. The name is from the Greek στίβι stibi through the Latin stibium as the old name for the mineral and the element antimony.
