At Golden, Colo., this month, a pilot unit for electrowinning copper from solution is coming into operation. At the heart of the unit is a cell of unusual design developed jointly by the Colorado School of Mines Research Foundation in Golden and by Continental Copper and Steel Industries, Inc., New York City. The new cell surmounts a number of economic and technical hurdles normally associated ...
