The development of regrind, In porphyry/skarn copper-gold flotation plants gold recovery is often well below copper recovery [1] With liberated and copper-associated gold readily recovered in the flotation stage, this recovery difference is often due in part to operating strategies that require rejection of gold-bearing iron sulphide gangue minerals in order toTreatment and Recycling of the Process Water in Iron Ore ,, The samples for flotation were taken from on-site samples of flotation, which were ground to 95% passing 0045 mm, and contained 3490% specularite and hematite, 870% magnetite, 020% limonite, 3940% quartz, 1140% chlorite and hornblende, and 490% calcite and dolomite17, negative effect on gold flotation Use of lime often results in the depression of native gold and gold-bearing sulphid The optimum flotation pH ranges between 85 and 100 The type of frother also plays an important role in the flotation of native gold and gold-bearing sulphidEffect of pH on Copper Flotation Recovery VS Mass Pull, An example of testing the effect of pH on rougher flotation on pit samples and the results are presented Since this is only an example, it needs reminding that not all ores will respond the same Here, rougher flotation is most Selective at a pH of 95 as pH levels in the 9 to 10 range yielded 1% to 2% better recoveri Mineralogy data also supports this and shows between 3% and 10% of the ,reverse flotation of iron ore philippines, Recovery of Iron Ore Tailings byColumn Flotation pH values in levels usually applied in the reverse flotation of iron ore ie between 89 and 110 The results presented in Figure 6 show that the rise in pH led to a significant rise in the recovery of Fe in the concentrate The content of SiO 2 diminished for pH values up to 105 and the Fe content ,.
