Abstract
It is shown that mineral mining and processing operations produce inflow of highly toxic arsenic compounds in considerable amounts to water bodies. Among the promising methods for arsenic removal from aqueous media are the sorption technologies using available natural adsorbents and oxidizers. Results obtained from the experimental removal of arsenic compounds by adsorption on magnesium- and manganese-bearing minerals are studied. It is found that the use of this natural mineral material can essentially enhance efficiency of the environmental strategies in mining and mineral processing industries.
