Abstract
AbstractThis article is dedicated to the investigations of the individual complex processing of the high ferriferrous sulphide lead concentrates by the way of lead blast furnace reducing melting. The data of the trials series of high ferriferrous lead sinters' reduction melting with the operating blast furnace have been presented. The results of investigations indicate that low lead losses with the slag (1.4÷1.8 wt.‐%) can be achieved by maintaining a slag composition of 38.4÷41.1 wt.‐% FeO and 0.70÷0.74 CaO/SiO2 ratio, with a lead sinter throughput – 55÷60 tonnes/m2 · day. The slag liquidus temperature is estimated to be ˜1170°C.
