    Flotation responses were studied in both laboratory and pilot plant tests Pilot plant flotation responses were similar for both samples resulting in grades of 122 pct Cu and 25 pct Ni for the pit sample and 122 pct Cu and 21 pct Ni for the shaft sample Weight recoveries were 25 pct for the pit sample and 52 pct for the shaft sampleThe flotation experiments were performed in a 05 L mineral separator MS type laboratory flotation cell to upgrade recoveries of Cu and Ni bulk flotation from mine tailing

  • The influence of electrolytes present in process water on the flotation behaviour of a Cu Ni containing ore Thus the purpose of this study was to investigate the effect of typical electrolytes present in process water on the flotation of a Merensky oreThe Ni II ion flotation kinetics with sodium dodecylsulfate as collector was studied with the aim of developing new models to predict the flotation rate constant k of Ni II ions and water

  • Figure 1 shows an example of different water qualities used in a beneficiation plant resulting in poor Ni flotation All mineral flotation processes are sensitive to process water recycling issu PY Series spring cone crusher flotation copper plant zambia Copper Ore Flotation Process Copper Ore Flotation Plant Process Introduction Various cobalt bearing minerals have economic significance including cobaltite CoAsS carrollite Cu CoNi 2S4 and linnaeite Co3S4 These are often associated with copper minerals and pyrite and pyrrhotite iron sulphid Two different flotation separation strategies are used
