2009.4.22 Antimony, a toxic metalloid similar to arsenic, is present at variable levels in most gold-bearing rocks. Antimony is soluble in the surface environment, so antimony (Sb) mobilization in mine waters is an environmental issue around gold mines. The Reefton gold mine was originally developed in gold-bearing quartz veins; Sb concentrations were

Stibnite or antimonite is sulfide metalloid mineral of antimony with chemical formula (Sb2 S 3 ). The color is shiny lead-gray tarnishing to black with massive, granular, radiating, and elongated crystals habits ( Fig. 1.50 ). The mineral contains 71.7% antimony in its natural purest form. Stibnite crystallizes in orthorhombic system, needle ...

2021.4.1 The raw material, gold-bearing sludge with arsenic and antimony, was collected from a gold smelter in Xinjiang Province, China. In the smelter, the chlorination roasting method was used to extract precious metals (gold and silver) from the cyanide tailing, which is usually contains gold 5–25 g/t (Ellis and Senanayake, 2004).

2016.1.1 Not all copper scrap contains gold, but it has been estimated by Boliden that about 4.4% of the total WEEE ends up as smelter-grade electronic scrap after sorting/separation, assaying 18.3% Cu, 670 g/t Ag, and 63 g/t Au. The treatment of this type of material has required the development of specialized equipment and technology at the

The Consolidated Murchison ore contains antimony which, during gold extraction, is thought to act as an oxygen scavenger (Monhemius, 1987), while increasing both cyanide and lime consumption. There is also evidence that the gold becomes passivated in the presence of antimony sulphides during normal cyanidation (Millard, 2005; Rohner and Millard ...

2019.8.1 Arsenic and antimony are environmental pollutants associated with several diseases, including skin cancer. One of the main sources of both elements is the oxidation of sulphide minerals, particularly arsenopyrite and therefore any of both elements is a concern in gold mining operations because arsenic- and antimony-bearing sulphides may contain

2017.12.19 The most common antimony ore mineral is stibnite (Sb2 S3 ), but more than 100 other minerals also contain antimony. The presence of antimony in surface waters and groundwaters results primarily from rock weathering, soil runoff, and anthropogenic sources. Global emissions of antimony to the atmosphere average 6,100 metric tons per
