Kinross follows wellestablished mining practices to prevent the release of arsenic during the mining process. Arsenic is naturally present in the ore and remains in its original mineral form. During the mining process, it is disposed of in lined facilities and designed specifically for disposal called "specific tanks".

Arsenic is found in rocks containing many other elements, and is often released in the process of mining and smelting other metals. Mining and smelting sites often pose serious risks to local communities, particularly to children. Arsenic cannot be destroyed, and thus remains in surface soil long after the event that released the arsenic has ...
Arsenic (As) is classed as a semimetal, or metalloid. In nature it is commonly found as a metal in low levels in most soils and in higher concentrations associated with some copper, lead and zinc ores. The most common arsenic mineral is arsenopyrite, a compound of iron, arsenic, and sulfur. Relation to Mining
Oct 01, 2009· Arsenic occurs naturally in the earth''s crust, and much of its dispersion in the environment stems from mining and commercial uses. In industry, arsenic is a byproduct of the smelting process (separation of metal from rock) for many metal ores such as . cobalt, gold, lead, nickel, and ; zinc.
Jul 18, 2013· The processing of gold bearing sulphide minerals which contain arsenopyrite and other complex arsenic sulphide minerals results in arsenic containing emissions and effluents which must be given careful consideration in relation to clean air and clean water standards. The sources of arsenic .
Arsenic is a greyappearing chemical element (atomic number 33, symbol As in the periodic table) also termed a metalloid. Arsenic can exist in a metallic state in three forms (yellow, black, and gray; with gray predominating) and in ionic forms. Arsenic is considered to be a heavy metal, and arsenic ...
Mining and Ore Processing Mercury Pollution. Estimated Population at Risk: Million. Description. Mining and ore processing occurs throughout the world and consists of extracting minerals, metals, and gems from surrounding earth and ore. Industrial mines vary in size, with some being quite small operations and others very large.
Arsenic mine tailings and health Arsenic is a substance found in the environment. It occurs naturally in crushed rock. It is often found near gold deposits and is extracted as part of gold and other mining activities. The waste left over after mining processes is called mine tailings.

world, Latin America, has high arsenic content in many of its ageing copper mines. With many of the upcoming projects also having high arsenic content, the volume that needs to be treated is set to increase, intensifying the environmental and financial risk to producers. Although different processing methods result in different arsenic

The majority of arsenic emissions, worldwide, are as compounds such as minerals and xide. Goldmining and processing operations were primarily used for Table So, for example, some coppermining and processing operations (, Olympic Dam, in Australia) that may produce significant gold were not used in this analysis.
Arsenic in Waste from Coal Mining, Processing, and Storage Mining operations in the United States generally must meet waterquality standards for discharge of mine water. In some abandoned mines or undisturbed pyriterich strata, however, decomposition of pyrite in coal and rock can lead to dispersal of arsenic to the environment. For example, in

Removal of arsenic from mining process waters is therefore a prime concern and a number of technologies have been developed for this purpose. Precipitation with trivalent iron salts and lime is most commonly applied in mining effluents for arsenic removal ( Hamberg et al., 2016).
With environmental regulations becoming increasingly stringent, arsenic looks set to pile ever more pressure on copper producers. 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 ...
Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination is the most commonly used leaching process for gold extraction..
