Read MoreSimilarly, at the same (fine) grind size, zinc recovery at target concentrate grade can vary by 20 per cent (Figure 5). 4 The laboratory flotation tests shown in Figures 4 and 5 were conducted to evaluate ores using a laboratory flowsheet similar to current plant operation.
Read MoreZinc in the lead concentrate was also lowered from 15 to 8 percent. Results of ultrafine grinding on selective lead recovery are shown in table 7. Since some fine sphalerite floated with the galena and some fine galena was lost to the flotation tailings when conventional collectors were used, another collector for galena was considered.
