    · of the flotation process where fine silica is floated using aminebased collectors at pH ranges from 65–8 Reverse flotation can be applied for phosphate ores that have high carbonate and low silica content The grade of P2O5 in the tailing products depends on silicate content in the feed When silicate content is lower in the feed, the P2O5 grade is higher in the tailings, and vice versa• Proposed a new flotation tailings purification process Abstract Flotation waste, which was produced through seventy years of copper ore processing in RTB Bor, Serbia, is deposited in a flotation tailings pond In total, almost 264 Mt could be considered as available for eventual reprocessing and reuse Chemical analysis has shown that an average concentration of targeted metals in theREPROCESSING OF THE OLD FLOTATION TAILINGS DEPOSITED· The total copper recovered from its ore through flotation process is about 56% [6,18], which indicates that the flotation tailings still contain valuable copper components such as chalcopyrite In addition, old flotation tailings sometimes have a higher copper grade (02–04%) than that of low‒grade ores (02‒03%) These copper grades of the old flotation tailings are similar to theDevelopment of copper recovery process from flotation
