Lead Zinc Sulfide Separation by Sequential Flotation
Apr 27, 2016 Conditioning with the zinc depressants and lead flotation reagents is accomplished right in the grinding circuit; hence, only in special cases is it necessary to include a conditioner ahead of the lead cells Lead rougher tailings are conditioned in a Super Agitator and Conditioner Mar 08, 2016 Selective flotation (sequential) flowsheet of three metals ORE TREATED: Sulphide ores of lead, copper and zinc are primarily treated This flowsheet can also be applied to other ores wherein the separation of base metals or nonmetallic Sequential Selective Flotation Process FlowsheetThe established leadzinc ore flotation processing scheme is to add zinc sulphate (ZnSO4) to the grind to control metal ion activation (sphalerite depression) Often metabisulphide or other sulphidation chemicals are added with the zinc sulphate for iron sulphide mineral depressionLeadZinc ores Danafloat

Flotation is generally indispensable for the separation of leadzinc ores As far as the flotation process is concerned, it can be divided into a priority flotation process and a mixed flotation process, that is, whether there is floating lead first and then floating zinc, or if the lead and zinc The main usful elements in a flotation tailings in Inner Mongolia were lead, zinc and silver, and the main lead and zinc minerals were oxide minerals The content of sulfide minerals of lead and zinc especially sulfide mineral of lead were small,so It was difficult to get concentrate of sulfide mineral of leadThe flotation tailings was used as theExperiment study on recovering lead and zinc from a Apr 01, 2016 In order to improve the flotation results, laboratory scale flotation testing of ore samples taken from this operation was performed Flotation tests used a sequential recovery protocol for selective flotation of first the lead and thereafter the zinc The key parameters that influence flotation performance of lead mineral were tested in this The critical importance of pulp concentration on the
