Abstract
As the basis for the state of Minnesota's regional copper-nickel study environmental evaluation, hypothetical mine models were developed ranging in ore capacity from 5.35 to 2.00 X 10-6 mtpy. Open pit and undeground mining operations were defined utilizing conventional methods of ore extraction. Processing of the copper- nickel sulfide material involved conventional bulk flotation of the valuable minerals, with maximum water recycle and tailing disposal. Flash smelting and electrolytic refining of the concentrate resulted in 0.10 X 10-6 mtpy copper plus nickel metal, plus associated cobalt and precious metals. Variations in model parameters allowed environmental trade-offs to be identified.
