acco phos depressant for coppe lead zinc ores flotation in papua new guinea

In the mining industry cyanide is primarily used for leaching gold and silver from ores but it is also used in low concentrations as a flotation reagent for the recovery of base metals such as copper lead and zinc At many of these operations cyanide treatment systems may be required to address potential toxicity issues in regard to the health of humans wildlife waterfowl or aquatic life

Mar 01 1992 · It is used as depressant for pyrite in copper and coppermolybdenum plants NariS Sodium hydrosulfide is a commonly used reagent to depress copper and iron sulfide minerals in byproduct molybdenite flotation plants ZnS04 Zinc sulfate is used to depress sphalerite in leadzinc and copperleadzinc flotation plants

CopperLeadZinc ores In most cases lime is used as a pyrite depressant but some operations prefer soda ash because lime tends to depress precious metals As described in the leadzinc process description in some instances enhanced iron sulphide depression can be improved by aeration prior to the differential CuPb flotation step

The alternative flowsheet to this is bulk flotation of all sulfides followed by sequential flotation of copper–gold from a bulk concentrate This flowsheet is shown in Figure 1227 The effectiveness of this flowsheet is studied on the OKTedy ore Papua New Guinea and on the Cerro Corona Peru ore These results are compared in Table 1217

Because most of the iron sulphides also report to the lead flotation tails and so feeds the zinc flotation circuit typically lime is used to raise pH for iron sulphide depression The flotation collectors used in sphalerite flotation tend to be less powerful because sphalerite at this stage typically readily floats and using a more aggressive Get Price Flotation of mixed copper oxide and sulphide minerals with
