reclamation process of limestone

Reclamation - an overview ScienceDirect Topics

Wet reclamation process has found difficulty in application because of the problem of discharging the effluent water into rivers. Up to 2000 gal of effluent with solids content of about 10,000 parts per million would be produced which is about 8–10 times higher than that laid down by law.
