| Abstract: |
| In the process of cyanide leaching at concentrator No1 in Yindongpo Gold Mine,there are some difficult problems including low gold leaching rate,froth overflow which causes gold loss and high slime content of cyanide residue which affects seriously the comprehensive recovery of useful metals in the residue.With a new proposed process of combining grinding fineness with reagent rate,these problems have been solved.The results show that the gold concentrate grade is increased from 39.43% to 53.19% and overall recovery of gold flotation-cyanide leaching from 80.92% to 90.54%. |
