  • Selective and efficient extraction of lead from mixed

    Recently, with the increasing consumption of zinc resources, the effective extraction of zinc from mixed ore by hydrometallurgical method has attracted much attention (Jia et al, 2016; Moradi and Monhemius, 2011), but the extraction and utilization of lead is not considered in this process, which leads to the waste of Pb resources andA major and primary Lead mineral is galena (PbS) which comprises of 866% of lead In order to smelt this mineral, a blast furnace is needed to be used A blast furnace is an enormous oven which is used to accomplish the smelting processes According to their properties and applications, lead alloys can be classified into: corrosion resistant alloys, battery alloys, solder alloys, printingLead: smelting, producing and classificationMetalpediaThe ore is ground at the mill, leaving it in particles with diameters of 01 millimeter or less 5 Flotation • The principal lead ore, galena, is properly known as lead sulfide, and sulfur makes up a substantial portion of the mineral The flotation process collects the sulfurbearing portions of the oreExtraction of Lead SlideShare
