“…Other attempts have been done to separate As from Cu in earlier steps such as flotation (Long et al, 2014) or during the smelting process (Mihajlovic et al, 2007). In general it was concluded that it was difficult to separate Cu from As before or during smelting.…”

“…[4][5][6][7][11][12][13][14] Pyrometallurgy processes containing methods of oxidation roasting, reduction roasting and chlorination roasting, usually lead to secondary arsenic pollution and high energy consumption. 15,16) Most research focused on treatment of arsenic-bearing materials by hydrometallurgical methods.…”

“…The process is one of the more common physical separation and leaching methods for treating granular solid wastes and contaminated soils and sediments. Washing is also used to remove arsenic and other contaminants from ore deposits prior to smelting and from coal before combustion (Mihajlovic et al, 2007;Chapter 5). Chemicals that can promote the leaching or extraction of arsenic from solid materials include oxidants, EDTA (ethylenediaminetetracetic acid; Lee et al, 2004;Englehardt et al, 2007), supercritical carbon dioxide (Wang and Guan, 2005), solutions containing citric acid (C 6 H 8 O 7 ) and KH 2 PO 4 , or a series of washes with HCl and NaOH (Jang, Hwang and Choi, 2007b).…”
