Application of dispersion inhibitor EMLT-1 in copper flotation

Beneficiation test was done on copper waste rocks which were extremely sliming and copper content of only 0.27%.Dispersion inhibitor EMLT-1which made slimes dispersed efficiently and depressed silicate minerals was successfully developed.In addition,EMLT-1had weak inhibition for copper.By using the EMLT-1 in laboratory experiments,through one-roughing,one-scavenging and three-cleaning separation,the copper concentrate of 17.06% Cu was obtained with the recovery of 83.43%,copper grade and recovery of copper concentrate was greatly raised.Pilot test based on laboratory experiments confirmed the reliability of those from laboratory tests.
