<p>A resource utilization and harmless treatment method for cyanide tailing ore pulp is provided. In the method the cyanide tailing ore pulp that contains cyanogen, thiocyanate, heavy metal and arsenic is directly mixed with the liquid that contains hydrogen peroxide. The method has a high oxidation reduction reaction speed and blowing-off speed, a short treatment time, few addition agent and lower costs. Furthermore, by using the method the conversion rate of thiocyanate in the ore pulp can be greater than or equal to 88% and the overall recovery rate, compared with the clear press filtrate of treating ore pulp of the same type, can be improved more than 20%.</p> |
