extraction and beneficiation of aluminium

Aluminum Manufacturing

The production of aluminum begins with the mining and beneficiation of bauxite. At the mine (usually of the surface type), bauxite ore is re-moved to a crusher. The crushed ore is then screened and stockpiled, ready for delivery to an alumina plant. In some cases, ore is upgraded by beneficiation (washing, size classification, andIdentification and Description of Mineral Processing ...2016-3-27 · EXHIBIT 5-1 SUMMARY OF EXTRACTION /B ENEFICI ATION AND M INERAL P ROCESSING W ASTE S TRE AMS BY C OMMODITY Commodity Waste Stream Nature of Operation Alumina and Aluminum Water softener sludge Extraction/Beneficiation Anode prep waste Mineral Processing
