This is necessitated from the fact that the vats are placed in a row at right angles to the discharge end of the bin. The conveyor proper is a sixteen inch rubber belt, the first conveyor fifty feet long and the second, forty feet long. The speed of the belt is 600 feet per minute. By these means a vat is charged in from two to two and one-half hours, accomplishing a great saving in time over the old method of charging by cars. The tailings are discharged from the vats by sluicing with a water ...pressure of sixty to sixty-five pounds per square inch.
The time needed to discharge a vat is two and one-half to three hours. The favorable situation of the mill gives unlimited grade to carry off the tailings.
While the vat is filling, and about one-half full, the strong solution is turned on, six pounds of Potassium Cyanide per ton of solution. The amount of strong solution run on is about fifteen tons, which is allowed to stand three to four hours generally, sometimes much longer, according to the nature of the ore.
