    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 batteries and ammunition). Arse

    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

    Gold cyanidation - Wikipedia

    Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.It is the most commonly used leaching process for gold extraction.. Production of reagents for mineral processing to recover gold, copper, zinc and

    ARSENIC IN GOLD LEACHING

    If arsenic is present, regardless of what form, solubility increases with higher pH. Environmentally; during or after detox, the arsenic can be precipitated via ferric sulphate leaching to produce the highly insoluble ferric arsenates which will settle, sometime requires the use of flocculant, in the tailings pond.

    Copper-Arsenic Processing - Teck

    The CESL Cu-As Process has achieved greater than 99% deportment of arsenic to leach residues (the by-product of the metallurgical process). Arsenic components in the residue have been identified, with the use of advanced mineralogical methods, as basic ferric arsenate (BFAS) and scorodite both of which are considered the most stable forms for arsenic fixation.

    Developments in Arsenic Management in the Gold Industry

    The majority of arsenic emissions, worldwide, are as compounds such as minerals and trioxide. Gold-mining and -processing operations were primarily used for Table 41.2. So, for example, some copper-mining and -processing operations (e.g., Olympic Dam, in Australia) that may produce significant gold were not used in this analysis.

    DescriptionRelation to MiningUsesArsenic (As) is classed as a semi-metal, 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.

    Arsenic occurs in pure form only in small deposits. It occurs in many minerals, and usually is obtained as a by-product from the mining, processing and refining of other minerals. Common arsenic-bearing minerals include arsenopyrite, conichalcite, enargite, lollingite (iron arsenide), olivenite and orpiment.
