Removal of residual copper from nickel solutions AMAX
Residual copper is removed from acid nickel solutions by contacting said solution with activated particulate carbon which adsorbs the copper. The copper is subsequently stripped from the activated carbon by either a sulfuric acid leach (e.g. 2% H 2 SO 4) or by an ammonium hydroxide leach (e.g. 25% NH 4 OH).
