Delmonico Dump Mill
A small milling plant has been installed below the lower dump of the Delmonico mine and an attempt to recover the gold from the waste pile is being made. Two solution tanks, precipitate boxes and small gasoline engine for pumping constitute the entire plant.
The dump will be treated without crushing ore or removal. That part of the dump to be treated is first subject to saturation, so that the ground on which the dump is located may absorb all possible moisture.
The surface of the dump is then covered with lime and a strong solution of cyanide is sprinkled over it. This solution percolates the dump and is caught in a cement trough at the base of the waste pipe.
It is carried thence by pipe to the zinc precipitate boxes, the overflow is caught in a large tank and sunk to the solution tank on top of the dump.
