| Abstract: | The use of reactive polymer as heavy metal precipitant was tested to realize the wastewater reuse in the Pb/Zn flotation plants when cyanide was used as a depressant. Experimental results show that this method removes heavy metals from wastewater which are harmful to the selective flotation, and releases the bound cyanide. Thus, it could improve the flotation performance and save the consumption of cyanide. |
