arsenic mining areas

Are you living in an area with mine tailings? Arsenic and

In many gold mining areas, mine tailings have been used for landscaping instead of normal soil. Mine tailings often look like clay or sand and, as they contain finely crushed rock, they can easily produce dust. They are usually white, pale yellow or grey in colour. As the rock surrounding the gold often contains high levels of arsenic, mine tailings can contain high levels of arsenic too

IWRG431 Arsenic in mine tailings, sand & rock v4

In the gold mining areas of Victoria, arsenic is a naturally occurring compound in soil and rock. Gold mining works create tailings and leftover material such as rock, sand and earth which may or may not be higher in arsenic than the surrounding soil and rock. Given the long history of gold mining in some parts of Victoria, considerable stockpiles of this material containing high levels of

Arsenic Wikipedia

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. The primary use of arsenic is in alloys of lead (for example, in car

Environmental and human health risks of arsenic in gold

Knowledge of arsenic (As) levels in gold (Au) mining areas in the Amazon is critical for determining environmental risks and the health of the local population, mainly because this region has the largest mineral potential in Brazil and one of the largest in the world. The objective of this study was to assess the environmental and human health risks of As in tailings from Au exploration in the

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 in residential soil and household dust in Cornwall

First published on 1st March 2017. Exposure to arsenic (As) via residential soil and dust is a global concern, in regions affected by mining or with elevated concentrations present in underlying geology. Cornwall in south west England is one such area. Residential soil (n = 127) and household dust (n = 99) samples were collected from across Cornwall as part of a wider study assessing exposure
