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 ...

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).
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 ...
Increasing the leaching time generally resulted in higher arsenic extractions, as indicated by comparing the results from tests 3 and 6, and 5 and ideal leaching time was defined as that needed to extract enough arsenic such that a high extraction of gold would result from the cyanidation of the oxidative leach residue.
