Abstract

The paper examines the behavior of copper, lead, zinc and arsenic during the oxidative blowing of intermediate copper-lead matte, which represents the second stage of the general technology for processing balanced raw materials for copper and lead production. The optimal parameters for the oxidative blowing of intermediate matte have been established: the time of blowing the melt with oxygen is 20 min; the oxygen consumption is 1.4 times higher than its consumption from the stoichiometrically required amount for the oxidation of zinc and iron sulfide; the temperature is 1250 °C. High indicators have been achieved for the complex selective extraction of metals into targeted products: 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 general process flowsheet has been developed for separate processing of balanced charges consisting of intermediate products of copper and lead production. The technology can be used for separate processing of multi-component raw materials of copper smelters and lead production of various types and compositions.
