Abstract: The copper mineral of a certain copper ore dressing plant in Yunnan Dahongshan was recovered by flotation with butyl xanthate as collector,730A+2# oil as frother,of which the process had the disadvantages of large reagents consumption,unstable production process and poor production indexes.The flotation performance of the new efficient reagent was investigated.Results indicated that by using the site grinding fineness,flotation concentration and process in production,and with DF-64+DF-8(The mass ratio 1∶2)as collector,DF-K90 as frother,final copper concentrate with copper grade of 23.42% and recovery of 95.39% with 2.42 and 2.39 percentage points improved respectively was obtained.The new reagent can stabilize production process,and reduce reagents dosages and cost,with significant economic and social benefit.
