Flotation - Mineral Processing Metallurgy

Jan 11, 2016  One man per shift on a 250-ton plant will mean a cost of 5.4c. per ton in maintenance. Assuming a life of three months per blanket and 50 tons per cell and an allowance for repairs to blowers, motors, pumps, etc., we have ½c. per ton as a liberal estimate. Power at 1c. per kw. hour ($60 per hp.-year) and 2½ kw.-hours per ton equals 2.5c. per ...
