The different between bulk flotation and selective flotation is in bulk flotation in the concentrate you have all ores that you have in your slurry in selective flotation by the action of reactive you can have in the concentrate one ore that you want the quality of concentrate its better than bulk flotation

Differential flotation of copper cobalt ores differential flotation sequence a differential coppercobalt flotation separation which begins copperleadzinc ores industrial separation of nickel from nickel ore

The copper flotation step is inherently inefficient for cobalt with recoveries typically from 40 for oxides up to 80 for sulphides so there is a substantial amount of cobalt contained in tailings dams that could be recovered eg the kolwezi tailings project

Strategic metallurgy have demonstrated differential flotation techniques on a variety of copper containing ores to produce saleable copper concentrates application significant value has been added to our clients projects by producing a separate saleable copper concentrate through convectional process techniques projects

Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 9999 pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different
