Flotation Separation Experiment of Copper from Lead Concentrate of Nanjing Pb-Zn-Ag Mine
In order to reduce the copper content of Nanjing Pb-Zn-Ag Ore lead concentrates and obtain qualified copper concentrate, adopted K2Cr207 + CMC as lead combined depressants, Jiangxi university of science and technology researched and developed the LP-01 as copper collector to the lead concentrates on copper flotation separation in laboratory. The copper content of lead concentrate reduced from 1.01% to 0,41% ,and access to the copper concentrate with grade 18. 12% ,recovery 61. 05%. Based on the test in laboratory further industrial experimental was done,the lead concentrates with copper content reduced from 2. 85% to 1. 34% , and received copper concentrate grade 21. 68% , copper recovery 56. 39%. Industrial experiment also shows that the wastewater of copper concentrate and final lead concentrate containing Cr6+ can be recycled by the sodium sulfite + lime,thus maximum limit avoids Cr6+ pollution to the environment
