By analyzing the elemental composition and phase composition of typical lead-based solid waste, a collaborative treatment scheme of primary lead concentrate and lead-based solid waste was proposed. The proportion of primary lead concentrate and lead-based solid waste in the collaborative treatment process was determined by the industrial experiment. When the lead paste 9.47%, the lead dust 16.93%, the leaching slag 8.4% and the lead glass 0.93% were added, the production system could realize self-heating and the lead content in the reducing slag was less than 2%. Based on this technology, the large-scale oxygen bottom blow melting, bottom blow reduction and fume volatilization production system of reduction slag can process 750000 tons of lead-containing materials annually, and the maximum amount of lead-based solid waste can reach 35.73%.
