| Abstract: | The technological mineralogical characteristics of slowly cooled slag under vacuum are introduced.The test results indicate that the slag belongs to the medium re- ductibility,on the difficult side,and its coefficient of hardness is from 8to 1 6 .When the slag with grinding fineness of- 0 .0 1 6 mm amount to89% ,rough flotation and scavenging are conducted to throw away tailings,then the rougher concentrate is regrounded and re- treated,with Z- 2 0 0 ,SN- 9and ammonium dibutyl dithiophosphate as a mixed collector,the productivity of the final copper concentrate is4.5 9% .It contains Cu2 3.48% and Au5 .8g/ t.The recovery of Cu is 83.70 % .The tailing contains Cu 0 .2 2 % and Au 0 .1 8g/t. |
