2015-5-14 Atmospheric arsenic emissions from copper smelting represent the largest contribution of arsenic from the mining and metals industry by far and have been the focus of pollution control technologies and increasingly stringent regulations. [8] Arsenic can also be leached out of some metal ores by cyanide or acid rock drainage but can be captured and removed from wastewater before it is

1997-11-28 A chemico-toxicological similarity between arsenic and antimony exists and their toxicology is often seen. Indeed, both elements possess several common properties, e.g. they are clastogenic but not mutagenic in the trivalent state and they have a carcinogenic potential: trivalent arsenicals are known to be human carcinogens and antimony(III) oxide (by inhalation) has been shown to cause lung cancer

2006-7-12 Arsenic and antimony concentrations in water and sediment samples collected from Prestea, a gold mining town in the Western Region of Ghana and its environs were studied. The concentrations of these elements were measured using instrumental neutron activation analysis (INAA). INAA was preferred to other modern analytical techniques because of its relatively higher selectivity, sensitivity

2019-1-14 Mining and Arsenic. Arsenic occurs in various mineral forms, as arsenides in sulphide minerals and as arsenates. The most common mineral is arsenopyrite (FeAsS), which is also found in arsenolite (As 2 O 3), olivenite (Cu 2 OHAsO 4), mimetite (Pb 5 Cl(AsO 4) 3 and cobaltite (CoAsS).. In the weathering of sulphides, arsenic can be oxidised to arsenite and arsenate.
