FLOTATION COST The oil-mixtures generally in use will cost from 1.25c. up to 3c. per lb. depending on the proportion of cresol and other high- priced oils used, but 1½c. per lb. will be a safe average on most oils. A consumption of 1 to 1½ lb. per ton or from 1.25c. to 4.5c. per ton of feed, say 2½c., would be a safe average.
