Antimony
Techniques for the processing of antimony-bearing ores encompass a wide range of techniques from traditional hand sorting, which is dependent on plentiful and cheap labour, to technologically advanced, capital-intensive mineral processing. The main antimony products in international trade are stibnite and subordinate stibnite-berthierite …
The leaching characteristics and changes in the leached …
tent from different antimony-bearing ores is very different. The maxi-mum of antimony content is as high as approximately 66%, compared with the minimum of 0.066% by weight. Overall, high-grade antimony raw ores, such as ores from the Banxi, Zhazixi, Xinghua and Muli anti-mony mines, exist mainly in the form of Sb 2S 3, which has been con-
INNOVATIVE PROCESSING AND …
Antimony is a valuable mineral component in gold-bearing ores though it is an attribute of a rebellious ore as a chemical depressor of gold in cyanide treatment circuit [4]. Each of more than 18 antimony minerals, which can be present in gold-bearing ores, behaves specifically in ore preparation and cyanation.
Antimony ore in the Fairbanks district, Alaska
Antimony-bearing ores in the Fairbanks district, Alaska, are found principally in two areas, the extremities of which are at points 10 miles west and 23 miles northeast of Fairbanks; and one of two minor areas lies along this same trend 30 miles farther to the northeast. These areas are probably only local manifestations of mineralization that affected a much …
Effect of antimonate on the bacterial oxidation of sulfide …
The processing of persistent gold-bearing ores includes collective flotation of the sulfide minerals in the ore, bacterial oxidation of the concentrates, and cyanation of the cakes obtained by leaching. ...

Antimony leaching from tetrahedrite-bearing ores was typically carried out by using Na 2 S-NaOH solutions. In the current paper, the detail mechanism of …
Possibilities for the Environmental Processing of Gold-Bearing Ores …
Hydrometallurgical methods can be used to treat gold, arsenic, antimony, tin, and mercury contained in minerals, concentrates, and ores, as well as in complex compounds bearing any number of metals. Tetrahedrite leaching can be divided into two important dissolution mechanisms: alkaline and acid leaching [32,33].

The main purpose of this study is to characterize and separate antimony from a stibnite concentrate through a low-temperature sulfur-fixing smelting process. This article reports …
Geochemical behaviors of antimony in mining-affected …
Antimony (Sb) is a harmful element, and Sb pollution is one of the typical environmental issues in China, meaning that understanding of the geochemical behaviors of Sb is the key to control the fate of environmental Sb pollution. Sb tends to migrate in soluble form in the water–sediment system, but the fate of dissolved Sb is poorly known. …
