Tailings Dry Discharge Process FULIN MINING Application It is mainly used for concentrating and dewatering technology of tailings of mineral processing plants so as to achieve the purpose of dry heap of tailings and thus avoid environmental pollution
Tailings are created as mined ore is processed through crushing grinding and milling mined ore is moved to the dry stack includes dewatering to a filtered wet or dry discharge limits is based on downstream beneficial use tailings fact sheet page 3
