NOUFERROUS METALLURGICAL EQUIPMENT

Based on the analysis of the characteristics, composition and physical properties of lead-based solid waste, the reaction mechanism of primary ore smelting with lead-based solid waste under the conditions of bottom blow oxidation smelting, direct reduction of pulverized coal by bottom blowing and fuming is expounded. The process indexes of primary ore smelting with multi-form lead-based solid waste under the hot state test are listed. The process operation indexes and the engineering application effect on refractory life, lead content in reduction slag, production cost, waste slag, waste gas and waste water after application of demonstration project are summarized. The annual treatment of lead-based solid waste in the demonstration project can reach 270,000 tons, which reflects the superiority of the primary mine cooperating with multi-form lead-based solid waste smelting technology and large-scale equipment.
