Copper recovery

Rates of Cu++ removal from waste solutions by cementation on a perforated reciprocating zinc disc were studied under different conditions of frequency and amplitude of oscillation. Disc pulsation was found to increase the rate of cementation by a factor ranging from 2.8 to 5.5 compared to cementatio

Carboxyl methyl cellulose (CMC) as a water-soluble metal-binding polymer in combination with ultrafiltration (UF) was used in a hybrid approach for selective removal and recovery of copper from water. In the complexation–UF process the cationic forms of heavy metals were first complexed by a macro l
