Apr 10, 2019· Abstract. 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.
Ores containing silver in Arsenic and Antimony combinations offer considerable difficulties in cyanidation and it has usually been considered that the removal of these compounds by concentration was the only way to deal with them. G. H. Clevenger, however, when working on the ores of the Nipissing Mining Company of Ontario, Canada, found that by grinding exceedingly fine and treating with ...
The effects of arsenic and antimony sulphide minerals on the extraction of gold from a synthetic ore consisting essentially of free gold and glass sand were investigated. The amount of mineral added in each test was such that the synthetic ore assayed 0.25% As or 0.25% Sb.

Jan 21, 2015· Antimony enters the environment during the mining and processing of antimony-containing ores and in the production of antimony metal, alloys, and antimony oxide, and combinations of antimony with other substances. Antimony was mined in .
Antimony (Sb) - Chemical properties, Health and, Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat
• Starch xanthate effectively reduced antimony level to 0.5 mg/1. Further investigation into antimony removal by starch xanthate would be required for commercial application. Little is known about how other trace metals in the complex effluent would effect antimony removal.
Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes.

Heavy metals, primarily antimony, arsenic and manganese from antimony mines in Denali National Park, Alaska impacted all levels of the stream ecosystem. Decreased algal, moss and macroinvertebrate abundance (but not changes in macroinvertebrate trophic organization) were all clearly associated with mining activity in Slate and Eldorado creeks.
Antimony is mainly excreted from the human body via urine. Antimony and its compounds do not cause acute human health effects, with the exception of antimony potassium tartrate ("tartar emetic"), a prodrug that is intentionally used to treat leishmaniasis patients. Prolonged skin contact with antimony dust may cause dermatitis.
Potash Feldspar Melting . This article aims to study the technology of extracting potassium from potassium feldspar with molten salt leaching method and to analyze the effects of temperature, reaction time and other factors on extracting potassium, concluding the optimal process conditions of extracting potassium with molten leaching method from potash feldspar.

1. Introduction. Antimony (Sb) is an environmental contaminant widely distributed in the lithosphere, mainly in association with arsenic (As) in the presence of sulfides or oxides (Mitsunobu et al., 2006).Although natural processes release Sb into the environment, anthropogenic activities such as mining and industrial emissions are considered the primary causes of Sb pollution (Telford et al ...
