Moisture in wet concentrate has a negative effect on the performance of the smelting furnaces when it is fed directly to the furnaces, namely increasing the energy consumption and the offgas flow. There are several drying technologies available for drying copper concentrate, varying from direct heated rotary dryers and flash dryers to indirect ...
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 m long pan with a cylindrical bottom corresponding to an inner diameter of m and a maximum depth of m.
CiteSeerX Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract – By placing additional demands on energy and gas flow, the moisture content of a copper concentrate has an adverse effect on the smelting process. Different drying technologies, such as directly heated rotary dryers, flash dryers, and steam dryers, are available to solve this problem.
