Yuanjiang, Yunnan Copper Oxide Ore Flotation Technology,

Yuan Jiang ore is a copper oxidized ore; The main minerals are malachite, Chrysocolla, Chalcocite, The grade of run of mine is cu 1.13%, The oxidization extent of Copper is 84.07%. The combined copper oxide rate is 14.16%. The main minerals are irreqularity distributed. Yuan Jiang ore is a refractory copper oxidized ore because of its high content of ozidized copper minerals.With the use of Sulfurization-floatation. The new mixed collecting reagents (KSH-3) was tested in the Laboratory tests. The KSH-3 Collector was used in the commercial test, which proved that it could improve the recovery of copper oxidized ore. The out put of the concentrator was increased greatly with the stability of the recovery and the reduction of fineness of grinding.By adopting the-thchnology process recommended in the Eaboratry tests and the reagent dosage is the commercial test. The grade of concentrate is 23.40% Cu with a recovery of 88.32%.
