lead zinc sequential flotation

The grinding circuit as shown provides for removing the lead mineral as soon as free with the Unit Flotation Cell When grinding the average lead and zinc ore to minus 48 or 65 mesh the lead mineral particles overflowing the classifier will for the most part be all minus 200 mesh

ORE TREATED The most common of ores treated in this manner are lead zinc copperzinciron coppernickel but application may be made to other two or three mineral separations This flowsheet without a Unit Flash Flotation Cell or a Mineral Jig is applicable to ores where the

Copper Chalcopyrite and others As Lime is added and rises pH towards 12 depressed again is Iron pyrite followed by Zinc Activated Zinc in the Cu andor Pb Circuit will float like Copper More on SEQUENTIAL FLOTATION OF SULFIDE ORES

The 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 depression

The zinc reporting to the bulk flotation tails feeds the zinc circuit which is operated as previously described in the leadzinc flotation section Which flotation scheme used in the differential copperlead bulk concentrate separation is generally and often dependent upon which mineral has the greater mass in the bulk concentrate

Silver Lead Zinc Flotation Circuit 2 The recovery of silver minerals occurring in a leadzinc sulfide ore is efficiently accomplished using the above flowsheet The process consists of selective flotation to produce a mixed silverlead concentrate for maximum smelter return and a separate zinc concentrate
