Savage River Mines Concentrator and Pumping Operation

The Savage River Mines concentrator and pipeline has operated for seven years. During this time some problems of general interest have been overcome, particularly in the area of autogenous grinding in large mills and in pump- ing solids over long distances. The plant flow sheet and equipment at Savage River and the control techniques are. described. Ore type has varied widely over the per- iod of plant operation. Techniques developed to minimise the effect of variations on through- put are discussed'. The main technique is the controlled rejection or addition of grinding Media.
