This and observations made at other lead/zinc operations throughout the world suggest that it is possible to tailor the grinding chemistry of the system to achieve the best metallurgical performance by correct grinding media alloy selection. A one size fits all approach to the inclusion of high chrome grinding media within a circuit is not
As described in the lead-zinc ore processing section, zinc sulphate and metabisulphide sphalerite and pyrite depressants, respectively, are typically added to grinding. Then a Cu-Pb bulk concentrate is recovered with xanthate, dithiophosphate and flotation reagent blends. Collector selection in the bulk flotation step must consider impact on the subsequent Cu-Pb separation stage where a
• A modified grinding strategy where efficient grinding equipment is used and techniques employed to decrease grinding media consumption • A more reasoned and thorough approach to the selection of target product size for a comminution circuit involving a better understanding and interpretation mineral liberation data. Background
problems of over-grinding the galena-bearing minerals as the cyclones returned the smaller but heavier galena particles and coarser but lighter gangue particles to the underflow for further grinding. The effect of this phenomenon is illustrated in Figure 5. Figure 4: Closed-Circuit Tower Mill for Treating Bulk Lead/Zinc Concentrate 70 50

1. Introduction. Grinding is one of the very important unit operations in most of the mineral processing plants. Since grinding is a very energy intensive process, modeling and thereby optimization of grinding operation of industrial scale has been a continuous endeavor of the scientists and engineers.
The initial data showed that the use of a more inert grinding media could have increased zinc losses to the lead cleaner concentrate if careful attention was not paid to alloy selection.Diagnostic
