Research on Flotation Experiment of a Copper Containing Pyrite
The copper content of a copper-bearing pyrite in Jiangxi is 1.33%,of which copper oxide accounts for 15.79%and sulfur content is 32.24%.In order to develop and utilize the ore,a closed-circuit test was carried out with lime as pH regulator,APII as copper collector and butyl xanthate as sulfur collector under the grinding fineness of-0.074 mm accounting for 70%.The flotation indexes of copper concentrate with copper grade of 17.97%,copper recovery of 72.21%,gold grade of 4.69 g/t,silver grade of 160.53 g/t and sulfur concentrate with sulfur grade of 48.93%and sulfur recovery of 89.05%were obtained.The recov-ery and utilization of valuable metals in the ore are realized,which provides a basis for the efficient develop-ment and utilization of the ore.
