摘要:

黄金矿山在利用因科法处理氰化尾矿浆时,一般采用传统的敞开式曝气槽反应器,存在曝气弥散效果差、氧利用率低、对环境造成二次污染等问题。将传统的敞开式曝气槽反应器优化为旋流微泡曝气反应器,使氰化尾矿浆反应器具备pH调节、药剂投加与混匀、旋流微泡曝气与负压气体吸收等功能。反应器优化后,节省电力30 %,氧利用率超过25 %,可以高效、安全、环保地处理氰化尾矿浆。

Abstract:

When INCO method is used to treat cyanidation tailings pulp in gold mines,generally,conventional open aeration tank reactor is adopted,leading to poor effect of aeration dispersion,low utilization rate of oxygen,and secondary pollution to environment.In light of that,the conventional open aeration tank reactor is optimized into cyclone microfoam aeration reactor,adding functions to the reactor for  cyanidation tailings pulp such as pH adjustment,reagent addition and mixing,cyclone microfoam aeration and negative pressure gas absorption.With the optimized reactor,power consumption is saved by 30 %,oxygen utilization rate is improved by 25 %,the cyanidation tailings pulp can be treated in an efficient,safe and environmental way.
