Method of flotation of copper molybdenum ores

Method of flotation of copper molybdenum ores

Sep 01 2015 It is usually associated with copper sulfide ore as a trace mineral 13 In the flotation of coppermolybdenum sulfide ores two methods are widely used 1 the bulk copper molybdenum flotation followed by copper molybdenum separation 2 the sequential flotation of the copper and molybdenum sulfide minerals The known method of flotation of coppermolybdenum ore beneficiation including collective coppermolybdenum flotation in an alkaline environment created lime The bulk concentrate is treated with oxygen at a temperature of 6095C a pressure of 00510 MPa and pH110 selective flotation of copper and molybdenum concentrate emitting
