Live Chatprocess for the recovery of fine iron minerals in the tailings. The results showed that concentrates of grades ranging from The results showed that concentrates of grades ranging from 4162% can be attained with the selected processes.
Live ChatRecovery and dilution usually are interrelated with some methods of stoping a high recovery involves contamination of the ore from the walls or cappingand often clean ore can be obtained only by leaving some ore in the mine. In openstope mines the greatest loss of ore is that tied up in pillars left for support of the back or hanging wall. The amount of ore thus left varies considerably with the strength of ore
Live ChatThe bacteria that were detected all have roles in mineral bioprocessingeither (i) in catalysing the oxidation of ferrous to ferric ironthe main chemical oxidant of sulfide mineralsor (ii) the oxidation of sulfur coupled either to molecular oxygenforming sulfuric acidor (iii) the reduction of soluble or mineralphase ferric iron.
