The study examined the behavior of copper, lead, zinc, and arsenic during the reductive-oxidative processing of a balanced charge under scaled-up technology conditions. The optimal parameters for ensuring high comprehensive recovery of metals into targeted products were identified: lead into rough lead, copper into matte, and zinc into slag. The feasibility of conducting reductive-oxidative smelting of a balanced charge was demonstrated. Optimal technology parameters were established: gas blowing time with natural gas – 20 minutes; with oxygen – 20 minutes; methane consumption – 1.7 times higher than that from the stoichiometric requirement for the reduction of lead compounds; oxygen consumption – 1.4 times higher than that from the stoichiometric requirement for the oxidation of zinc and iron sulfides; temperature – 1523 K. High rates of comprehensive selective recovery of metals into targeted products were achieved: lead into rough lead – 97.6%; copper into matte – 98.6%; zinc into slag – 56.8%, into matte – 1.7%, into dust and gases – 41.5%; arsenic and antimony into dust – up to 97.4% and 90%, respectively. A balanced charge processing technology has been developed for processing substandard intermediates of copper and lead production.
