Abstract

Изобретение относится к способам переработки галенитсодержащих концентратов в цветной металлургии. Цель изобретения - повышение эффективности процесса переработки галенитсодержащих концентратов, исключение выбросов газов в атмосферу и утилизация всех попутно образующихся веществ. Сущность изобретения. В способе переработки галенитсодержащего концентрата окисление галенита осуществляют в реакторе с двойным корпусом, в межкорпусное пространство реактора подают нагретый водяной газ в соотношении H2:CO=1:1, полученный газификацией углеродистого материала при соотношении C:H2=1:1, теплом водяного газа нагревают галенито-воздушную смесь до температуры 1000°C, остаточным теплом водяного газа и продуктов окисления галенитсодержащего концентрата нагревают воздух, восстановление оксида свинца осуществляют водяным газом при соотношении H2:CO=1:1, из состава восстановительного газа выделяют водяной конденсат и получают двуоксид углерода, теплом смеси газов из окислительной зоны реактора нагревают уголь для получения углеродистого материала, далее данный газ используют для получения серной кислоты и чистых газов нитрогена и аргона. Преимущество изобретения. Предлагаемый способ позволяет получить черновой свинец по малоэнергоемкой технологии и попутно также серную кислоту, двуоксид углерода и чистых инертных газов. Способ не имеет отходов, загрязняющих природу, поэтому является экологически чистым.The invention relates to methods for processing galena-containing concentrates in non-ferrous metallurgy. The purpose of the invention is to increase the efficiency of the process of processing galena-containing concentrates, to eliminate gas emissions into the atmosphere and to utilize all associated substances. The essence of the invention. In the method for processing galena-containing concentrate, the oxidation of galena is carried out in a reactor with a double casing, heated water gas is supplied to the interbody space of the reactor in a ratio of H2: CO = 1: 1, obtained by gasification of carbonaceous material at a ratio of C: H2 = 1: 1, heated by warm water gas the galena-air mixture to a temperature of 1000 ° C, the residual heat of water gas and oxidation products of the galena-containing concentrate is heated, the reduction of lead oxide is carried out with water gas at a ratio of H2: CO = 1: 1, water condensate is separated from the composition of the reducing gas and carbon dioxide is obtained, Coal is heated by the heat of the gas mixture from the oxidation zone of the reactor to obtain carbonaceous material, then this gas is used to obtain sulfuric acid and pure gases of nitrogen and argon. Advantage of the invention. The proposed method makes it possible to obtain crude lead using low-power technology and, along the way, also sulfuric acid, carbon dioxide and pure inert gases. The method does not have waste, polluting nature, therefore, it is environmentally friendly.
