13-7-2017· The main limitation for recovering precious metals from those wastewaters is that the levels of precious metals are usually quite low (Bhagat et al., 2004; Ju et al., 2016). This means that conventional ion exchange resins, solvent extraction or reduction and precipitation methods of precious metal recovery by adding chemical reagents are not economically attractive.
