Arsenic is a poisonous element found within minerals at many of the world's copper mines. As a consequence of sulphide ore processing, arsenic is concentrated along with copper; this becomes more acute as the in-situ grade increases. The largest copper supply region in the world, Latin America, has high arsenic content in many of its ageing

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.

Arsenic Arsenic is a chemical element with the symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid. It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry.

After a slump in 1921, work began on the arsenic works in this scheduling. The works took ore mined in the west of Devon Great Consols, supplemented by ore reworked from 19th century dumps. After further price slumps, arsenic mining had ceased by 1925 but the works continued using dump ore until final closure in about May 1925.

Arsenic is a naturally occurring element commonly found as an impurity in metal ores, and is produced commercially for use in pesticides, wood preservatives, and metal alloys. Arsenic can be toxic in large doses, and the mining industry monitors and prevents its release into the environment. [32] Background.

Arsenic mining ceased in Australia in 1952 and in New South Wales in 1936, as the Ottery Mine ended production. As Godden suggests, it is unlikely that the mining of this resource will take place again, since the Bolidan copper mine in Sweden produces enough arsenic as a by product to satisfy world demand.
