The Role of Arsenic in the Mining Industry

Arsenic in the mining industry . 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

Arsenic mine tailings and health Better Health Channel

Dust and soil from mine tailings often contain arsenic, so keep exposure to a minimum. Health effects depend on the amount of arsenic taken in by the body over time and the amount of arsenic swallowed. Children are more at risk as they can swallow more soil or dust than adults. See your doctor if you have any concerns.

Naturally occurring sources of human exposure include volcanic ash, weathering of minerals and ores, and mineralized groundwater. Arsenic is also found in , water, soil, and air. Arsenic is absorbed by all plants, but is more concentrated in leafy vegetables, rice, apple and grape juice, and sea. An additional route of exposure is inhalation of atmospheric gases and dusts. During the Victorian era, arsenic was widely used in home decor, especially walls.

EnviroGulf Consulting Mining and Arsenic

Mining and ArsenicSources of ArsenicTechnical ServicesConsulting ServicesRelevant ExperienceArsenic 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 (As2O3), olivenite (Cu2OHAsO4), mimetite (Pb5Cl(AsO4)3and cobaltite (CoAsS). In the weathering of sulphides, arsenic can be oxidised to arsenite and arsenate. Arsenic oxide is also formed as a by-product of copper, lead and nickel smelting. The toxicology of arsenic and its compounds has at

Environmental occurrence and impacts of arsenic at gold

Arsenic is a common element in the natural environment and is frequently a significant component in gold deposits of the western United States.
