Telfer Copper Flotation

Importance Of Oxidation During Regrindingof Rougher

Nov 01 2014 unlike pyrite the oxidizing condition improves copper flotation due to the formation of hydrophobic oxidation species such as metaldeficient sulfide and polysulfide zheng and manton 2010 studied collectorless flotation in telfer coppergold operation they found that chalcopyrite was floated even without a collector due to the surface oxidation whilst pyrite did not float without a
