Ore Processing For Arsenic

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
