摘要:
采用硫酸铜作为活化剂进行闪锌矿和铁闪锌矿活化浮选一直存在着活化效率低、选择性差等问题,且活化过程一般需要在pH>11的高碱条件下进行,严重影响伴生银、锗和铟等稀贵金属的回收率. 为提高活化剂的选择性,降低矿浆pH,提高伴生稀贵金属的回收率,急需寻找一种新型高效活化剂. 活化剂X-43是一种硫化锌矿物的高效活化剂,可替代硫酸铜活化硫化锌矿物,并具有选择性活化的特性. 通过对云南文山都龙锌锡铜难选多金属矿进行优化药剂制度和工艺流程的试验研究,结果表明,与传统的活化剂硫酸铜相比,新型活化剂X-43能显著提高锌精矿中品位和回收率,锌精矿中锌的品位提高3.62百分点,回收率提高3.91百分点,并对硫化铁矿物具有一定的抑制效果.
Abstract:
Flotation of sphalerite and marmatite has some problems with copper sulfate as activator, such as low activation efficiency and poor selectivity, and the activation of sphalerite and marmatite at a high pH decreases the recovery of precious metal associated with sphalerite and marmatite. To improve the efficiency and the selectivity of activation processes and lower the pH value of pulp, a novel activator is necessary for activation of sphalerite and marmatite. X-43 is a kind of activator for Zinc Sulphide Ores. It can replace the conventional activator copper sulfate to active the zinc sulfide minerals, and its selectivity is good. Based on the optimal tests of the refractory Zn-Sn-Cu polymetallic sulphide ores in Dulong Mine, the results show that X-43 activates the refractory marmatite effectively, and depresses the iron containing sulphide ores to some extent compared with copper sulfate;the grade and the recovery of Zinc in Zinc concentrate increase 3.62% and 3.91% respectively.
