Reuse the water collected from the cooling area, flotation process and hydro transportation of final slag in the slag concentration process
c
Recycle the pickling solutions and the rinse water
d
Treat the residues (crude) from the solvent extraction step in hydrometallurgical copper production to recover the organic solution content
