    Abstract:

    Pyrometallurgical processing of copper-containing secondary raw materials and concentrates at industrial copper plants produce annually more than 1 million tons of furnace and converters dusts that are polymetallic materials with complex composition, containing mainly zinc, lead, tin as well as copper, iron and other impurities such as halogens and arsenic, that are undesirable for hydrometallurgical processing of zinc. A technology has been developed to treat these dusts that consists of two combined stages of pyrometallurgy and hydrometallurgy. Lead is removed during the pyrometallurgical stage while zinc recovers into the solution during the hydrometallurgical stage. Iron, copper, and other calcine components are dissolved, and a solid residue is obtained that concentrates tin. The purpose of this paper is to describe the hydrometallurgical stage that consists of high-temperature leaching of calcine and washing of cake. During this stage the zinc recovery into the solution is more than 98% and the tin recovery into solid product is 85%. Depending on tin percent in the original feed, the expected content of tin in the obtained concentrate is 14-20%, which makes a sellable product to the plants that specialize in the processing of tin-containing materials
