The successful cyanidation of gold ores containing appreciable amounts of arsenic or antimony sulphide minerals such as orpiment, realgar, and stibnite is usually difficult or even are low and the solutions soon become ''foul.'' The gold in such ores could be free and uncoated, and no trouble in dissolving it in clean cyanide solutions would be expected.
Six extraction media (acetic acid, EDTA, tetrabutylammonium hydroxide, NaOH, MeOH/H2O, acetonitrile/H2O) were tested for their ability to extract antimony (Sb) and arsenic (As) from freezedried poplar leaves, pine shoots and spruce shoots, as well as from a peat matrix.
Zinc, incidentally, does not dissolve in molten lead, and can be added to extract impurities by differential solubility. Lead is sold as soft lead, % pure, common lead (lead that has been desilvered), % pure, and corroding lead (for paint), % pure. Hard lead is alloyed with 6%18% antimony, which increases the strength of the lead.
1. Introduction. Antimony is primarily used for the production of alloys, flame retardants and brake pads (Uexküll et al., 2003).For industrial production, the pyrometallurgical methods involving volatilisation and reduction of sulphide ores were the primary means to extract antimony, which are high temperature (>1473 K) and high energy consumption (> × 10 10 J/t) processes (Habashi, 1997).

Zeng et al. (1991) and Zhang et al. (1998) used SE to extract antimony from a sulfide antimony ore of stibnite in 2 mol/L HCl system. Although the antimony leaching rate was found to reach >94% and 98% in the respective studies, some of the problems were still unsolved.
At least six principal methods are or have been used to extract antimony from its ores. The method used depends on whether the ore is a sulfide, an oxide, or a complex ore, and on the grade, which ranges widely from about percent to more than 60 percent antimony by weight.
It is further suggested that it is inadvisable to extract antimony from rich ores by fusing the sulphide with iron on account of the high fusion temperature required; if this process is adopted a reducing atmosphere should be employed and the dust in the flue gases recovered.
A new pyrometallurgical process to extract antimony from stibnite concentrate was proposed. Thermodynamic analysis of extraction process was conducted. Based on the thermodynamic analysis, the influence of volatilization temperature, volatilization time, blowing oxygen, low melting point slagging on the volatilization rate of antimony and the ...

Antimony is found in trace amounts in silver, copper and lead ores, and it is usually economically possible, as well as environmentally desirable, to extract the antimony from these ores when they are smelted. Most of the antimony mined each year comes from China, which supplies over .
The following photographic documentation of the process of extracting antimony from its ore made by one of my French correspondents and one of his colleagues. He says: "These pictures describe an experiment undertaken a few years ago related to the Dry path of antimony (or Stibnite Path) as followed by E. Canseliet and, I guess (but opinions ...

Antimony Wikipedia. Production process. The extraction of antimony from ores depends on the quality and composition of the ore. Most antimony is mined as the sulfide; lowergrade ores are concentrated by froth flotation, while highergrade ores are heated to 500600 °C, the temperature at which stibnite melts and separates from the gangue minerals.
The company mainly focuses on the precious metals gold, silver and palladium but can also recover up to 10 base metals including copper, lead, nickel, tin and antimony. Electronic material is generally shredded before it arrives at the plant.
Antimony is a metal found in natural deposits as ores containing other elements. The most widely used antimony compound is antimony trioxide, used as a flame retardant.
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 .
Nov 21, 2017· The work described in this thesis was aimed at studying a process(s) to extract secondary antimony compounds from waste. The first step was to identify antimony containing compounds as well as characterize each of the waste materials. Since there is a limited amount of antimony being recycled today, several techniques were investigated for ...
To make the metals medicinal of course one has to purify the gold from all impurities through laboratory methods and extract the Sulphur of the gold, the oiliness. This contains the medicinal properties of the gold. Of late there has been an interest in gold as a .
Antimony, a metallic element belonging to the nitrogen group (Group 15 [Va] of the periodic table). Antimony exists in many allotropic forms. It is a lustrous, silvery, bluish white solid that is very brittle and has a flaky texture. It occurs chiefly as the gray sulfide mineral stibnite.
Cupellation is a refining process in metallurgy where ores or alloyed metals are treated under very high temperatures and have controlled operations to separate noble metals, like gold and silver, from base metals, like lead, copper, zinc, arsenic, antimony, or bismuth, present in the ore. The process is based on the principle that precious metals do not oxidise or react chemically, unlike the ...
