摘要
针对某铜矿含泥量高导致的回收率低的问题,研究了药剂制度对矿石浮选的影响,通过优化浮选环境,使用了对镁硅酸盐脉石矿物及矿泥抑制效果显著的羟乙基纤维素,实现铜矿物与脉石矿物的高效分选,降低了50%的石灰用量,在低碱度环境下得到了铜品位为15.73%,铜回收率为80.78%的铜精矿。
The recovery rate of a copper ore was low due to its high mud content. The influence of reagent system on ore flotation was mainly studied. By optimizing the flotation environment, hydroxyethyl cellulose with significant inhibition effect on magnesium silicate gangue minerals and slime was used to realize the efficient separation of copper minerals and gangue minerals, and to reduce the amount of lime by 50%. The copper concentrate with copper grade of 15.73% and copper recovery of 80.78% in a low alkalinity environment was obtained.
