The cooled dore bars are secured in the refinery safe and the slag is fed manually into the ball mill for reprocessing. The production rate of the EXAMPLE Gold Mines processing plant is expected to be approximately 4000 troy ounces of combined gold and silver (dore) per day. Each refining day will produce 8-1000 troy ounce dore bars.
The production of final petroleum products differs from refinery to refinery, but in general, the oil refineries in the U.S. are engineered to produce as much gasoline as possible, owing to high demand from the transportation sector. (Figure text { } 2.4) shows the composition of output from a typical U.S. refinery.
