Method for comprehensively treating cyanidation tailing slurry by using gold ore waste rock yard leachate

The invention belongs to the technical field of comprehensive environment-friendly treatment methods for treating waste with waste, and particularly relates to a method for comprehensively treating cyanidation tailing slurry by using gold ore waste rock yard leachate. The method comprises the following steps: firstly, reducing the content of easily released cyanides in the cyaniding tailing pulp by using an oxidizing agent, then adjusting the pH value of the cyaniding tailing pulp by using the acidic gold ore waste rock field leachate, and then carrying out complex chemical reaction on the gold ore waste rock field leachate and various substances in neutralization liquid underflow and various substances in the cyaniding tailing pulp under an alkaline condition, and finally, the contents of pollutants such as cyanide and heavy metals are all reduced to a lower level, so that waste is treated by waste. 本发明属于以废治废综合环保治理方法技术领域，特别涉及一种利用金矿废石场渗滤液综合治理氰化尾矿浆的方法；首先利用氧化药剂降低氰化尾矿浆中易释放氰化物含量，再利用酸性的金矿废石场渗滤液调节氰化尾矿浆的pH值，然后再碱性条件下
