Preface
Arsenic is an abundant element in the Earth’s crust and occurs in more than 300 minerals, generally in combination with sulfur and metals with the formula MAsS and MAs2 (M=Fe, Ni, Co) to form arsenopyrite. Geogenic and anthropogenic activities can liberate arsenical compounds that range in toxicity, mobility, and bioavailability from arsenic-bearing minerals to the environment. Arsenic is highly toxic and adversely affects human health. It has been identified as the number one environmental chemical of concern according to the World Health Organization. Arsenic-containing minerals that occur in base metal ores and/or concentrates enter metallurgical processing circuits accordingly. Arsenic is found in the flue gas, dust, slag, residue, and sludge discharged from the copper, gold, and lead smelting process. Due to human activities, mainly through mining and smelting, arsenic can now be found in many more places than where they never existed before. Therefore, arsenic pollution has become a worldwide environmental chal
