The traditional sintering blast furnace lead smelting process has been faced with increasing challenges as the demand for environmental protection grows. In collaboration with many smelters, China General Engineering and Research Institute of Nonferrous Metals has carried out a series of key research projects with the bottom oxygen blowing-blast furnace lead reduction process. After the industrial and validation tests, the process has been adopted in two smelting plants and now in full operation. It has been shown in practice that the process is technologically advanced and shows remarkable environmental friendliness.
