As soon as the ore is freed from the base chlorides soluble in water, a solution of hyposulphite of lime (70) is led in from a tub or tank, on the ore, in order to dissolve the chloride of silver. This leaching is conducted like the former. It depends on the amount of silver how long this work continues—from eight to twenty hours. The clear cold so...
