Eliminating Copper from Gold Ore
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.

Types of Classifiers in Mineral Processing
CONE Classifiers are built in two types, one operating on the density of the pulp in the cone, and the other on the hydraulic or mechanical movement of the pulp. The Dewatering Cone is of the former type. The weight of the pulp in the cone actuates a lever with an adjusting weight, automatically controlling the discharge valve.
