Apr 27 2016 Lead Ore Grinding Circuit By far the most important lead mineral is the sulphide galena In many of the ores in which it occurs it is associated with sphalerite or marmatite and twostage selective flotation is necessary to separate the two classes of minerals When however the lead mineral is the only one of importanceand such ores Leadzinc sulphide ore contains lead sulphide galena and zinc sulphide sphalerite In the first flotation stage galena is rendered hydrophobic with an organic collector such as xanthate while sphalerite is kept from floating by depressants and in the second flotation stage activator was used to activated zinc flotation Since the organic regent used are different in the two flotation Lead Materials Ore Extraction Extracting Lead Materials from Ore Lead is a dense soft lowmelting metal Lead is the densest common metal except for gold and this quality makes it effective in sound barriers and as a shield against Xrays
