That such low efficiencies are tolerated in gold extraction is explained by the fact that, when “low solution” is going to be thrown away, it is obviously worth while to extract the last 2-c. worth of gold recoverable, if this can be done at the expense of 1 c. for zinc, making a fair allowance for refining cost. With zinc at 14.5 c. per pound, 1 oz. Troy costs 1 c. If this ounce is used
