The treated ore is then cyanided in the usual way and the gold recovered by electrolytic precipitation. Whether or not any precious metal was dissolved in the preliminary cyanide treatment was not stated. In another elimination method the copper mineral is dissolved out by means of ammonia after which the ore is cyanided as usual.
