圆型浮选机在焦家金矿6000t/d选矿厂的应用

Application of round-shaped flotation machines in Jiaojia 6 000 t /d capacity ore-dressing plant

浮选机是选别金矿、铜矿、钼矿、铁矿等的硫化矿物不可缺少的设备之一。系统地介绍了SJF10、SJF30圆型浮选机的特点以及在焦家金矿6 000 t/d选矿厂的应用情况。应用结果表明,在原矿品位4.20 g/t的情况下,精矿品位79.85 g/t,尾矿品位0.17 g/t,浮选回收率96.15%;同常规方形槽充气式浮选机相比,精矿品位提高6 g/t,浮选回收率提高0.8%,节能效果提高15%,减少占地面积30%,可提高3%~5%的经济效益,获得了良好的应用效果。

Flotation machines are one of the facilities used for processing sulfide minerals like gold, copper, mo- lybdenum and iron ores. The paper systematically introduced characteristics of SJF10, SJF30 round-shaped flotation machine and their application status in Jiaojia 6 000 t/d capacity ore-dressing plant. The application results show that when raw ores grade is 4.20 g/t, concentrates grade 79.85 g/t, tailings grade 0.17 g/t, the flotation recovery rate rea- ches 96.15 %. Compared with conventional square-shaped machines, the concentrates grade is improved by 6 g/t, flotation recovery rate by 0.8 % ,energy consumption is reduced by 15 % ,occupation area by 30 %. The machine helps increase economic interests by 3 % to 5 %, achieving satisfactory results.
