Abstract

Способ восстановления свинцового шлака, в котором шлак подвергают обработке путем инжекции через верхнюю погруженную фурму кислородсодержащего газа и топлива, причем нижняя головка вертикально подвешенной фурмы погружена в шлак. В результате инжекции в шлаке формируется зона горения, в которой горит топливо, и создается турбулентный режим, способствующий образованию на нижней части фурмы шлакового покрытия, отверждающегося в результате охлаждающего действия инжектируемого газа. Инжекцию осуществляют в восстановительных условиях, используя в качестве восстановителя сульфидный материал, с целью восстановления свинца шлака до металлического свинца и, тем самым, получения фазы расплавленного свинца, которая может быть выпущена в виде слитка сырого свинца.A method for reducing lead slag, in which the slag is treated by injection through an upper immersed lance of an oxygen-containing gas and fuel, the lower head of a vertically suspended lance being immersed in the slag. As a result of injection, a combustion zone is formed in the slag, in which the fuel burns, and a turbulent mode is created that promotes the formation of a slag coating on the lower part of the tuyere, which cures as a result of the cooling effect of the injected gas. The injection is carried out under reducing conditions, using a sulfide material as a reducing agent, in order to reduce the lead of slag to metallic lead and, thereby, obtain a phase of molten lead, which can be released in the form of a crude lead ingot.
