Economic Expediency of Copper Ore Mining with Waste

The economic expediency of developing the west wing reserves of Oktyabrsky Mine by cutand-fill method with cemented backfill of primary stopes and waste rock fill of secondary stopes has been determined. This method shows better performance in terms of ore loss and dilution as compared with the current mining system at the same quality of ore produced.

Host rocks for copper ore Economic Geology

Abstract. The Cu association with Ordovician volcanics of Newfoundland has long been known. Production has been disappointing, and exploration has failed to respond in a large way to the probing that has been carried on. That there are underlying reasons for lack of success is apparent to anyone familiar with the host rocks in the field.
