过去只用易选的北采区矿石生产高品位硫精矿,造成两采区高差悬殊,浮选尾矿水呈酸性,需处理后排放。采用南、北采区矿石混选工艺后,浮选尾矿水pH6.5,年节约尾矿水处理费45万元,磨矿处理能力提高20％～30％,球耗也有所下降。在原来二粗—精一扫流程的基础上将相选前两槽的精矿直接作最终精矿,回收率提高2.32％
In the past, only high-grade sulfur concentrates were produced using easily-available northern mining ore, resulting in large differences in elevation between the two mining areas. The flotation tailings were acidic and needed to be discharged after treatment. After adopting the ore mixing process in the south and north mining areas, the flotation tailings water has a pH value of 6.5, saving the tailings water treatment fee of 450,000 yuan per year and grinding and grinding capacity by 20% -30% and the ball consumption also decreased. In the original two crude - refined on the basis of the process will be selected first two trough concentrate directly for the final concentrate, the recovery rate increased 2.32%
