Indirect Drying of Copper Concentrate in a RotatingCoil Dryer
Abstract The Schlünder and Mollekopf [1] penetration model was used to simulate the drying of copper concentrate in a continuous indirect rotatingcoil dryer located at a Chilean industrial copper smelter The dryer consists of a 848 m long pan with a cylindrical bottom corresponding to an inner diameter of 277 m and a maximum depth of 166 mThe content of moisture in concentrate, which is left from the flotation stage, has adverse effects on the flash smelting process quality Thus, copper concentrate enters the dryer before being charged to the flash furnace and the moisture content of the concentrate is reduced from 7%–10% to less than 03%Moisture effect on the combustion of a single copper concentrate
