Flotation with air was commenced and six rougher concentrates were produced after 1 2 4 8 12 and 16 minutes respectively of flotation Additional talcose depressant was added after production of the 1 st and 3 rd rougher concentrates respectively The flotation products were assayed for nickel and copper4936
what is differential flotation process for nickel and sulfur recover cobalt and sulfur in the cobaltbearing VTi tailings The results showed that an optimized cobaltsulfur concentrate with a cobalt grade of 208 sulfur content of 3612 sulfur recovery of 8579 and cobalt recovery and 8477 were obtained by flotation process of one roughing three The tech nique proposed is a3909
a Copper if present in commercial quantities by solvent extraction b Iron and aluminum by hydrolysis with limestone or lime and filtering c Last traces of copper plus any zinc or cadmium present by H2S precipitation and filtering The resultant solution containing nickel4713
Copperselective solvents can be chosen and many steps are followed to get nickel and copper powder from the bleed The following block flow diagram was shown in a paper by A Agrawal et al in 2012 demonstrating the steps of SX for nickel and copper recovery Figure 54524
The final CuNi separation flowsheet was assessed in locked cycle flotation testing and the CuNi locked cycle test demonstrated substantial copper nickel separability An extended 10cycle test showed good stability within three cycles allowing reliable metal split factors to be collected over seven test cycles4648
Fig 4 Copper extractions from the copper smelter slag and the copper smelter slag flotation tailings as a function of time at different initial ferric iron concentrations By comparing Figure 2 and 4 it can be seen that both the copper extractions and the copper dissolution curves were similar in sulphuric acid alone and in the presence3969

AEROPHINE174 AERO174 and AEROFLOAT174 collectors promoters are used extensively for the flotation of sulfide minerals including copper gold lead zinc nickel iron and many others such as lithium These products provide improved performance and higher selectivity than more traditional sulfide collectors and better overall metallurgical3273
The Nova concentrator consists of a differential flotation circuit whereby copper bearing mineral are selectively floated prior to nickel flotation It is imperative that losses of copper to the nickel circuit and vice versa are minimised4194
Figure 1617 shows the copper concentrate grade as a function of level of lime and cyanide 1645 Other processes involved in treatment of coppernickel and nickel ores Some of the processes that are used in the flotation of coppernickel and nickel ores have been developed recently and are currently in use in a number of operating plants4747
The nonferrous metal chlorides may then be water leached separated purified and electrolyzed to recover copper and nickel metals and to regenerate chlorine for recycling AB A chlorination process for treating metal sulfide flotation concentrates is described4948
