Gold mine cyanide -containing tailing pulp innocent treatment pretreatment systems

The utility model discloses a gold mine cyanide -containing tailing pulp innocent treatment pretreatment systems, this system comprise two -stage deep -cone thickener, return water pond, two -stage surge tank, dashpot, pump and pipeline, and two -stage deep -cone thickener's upper portion overflowing liquid goes out water and all adds honeycomb duct introduction return water pond, are pumped by the pump in the return water pond, carry out cyclic utilization, one -level deep -cone thickener underflow goes into to carry out jia xinshui in the one -level surge tank and size mixing through the pump sending, transfers to get into the dashpot to the ore pulp overflow of suitable concentration, is promoted by the pump in the dashpot that to carry out the second grade to second grade deep -cone thickener dense, the second grade thickened underflow goes into to carry out jiaxinshui in the second grade surge tank and size mixing through the pump sending, transfers to get into the second grade dashpot to the ore pulp overflow of suitable concentration, treats further innocent treatment. After this system's preliminary treatment, the most cyanide among the former cyanide -containing tailing pulp can both obtain make full use of, and the ore pulp after twice new water is sized mixing pollutes content obviously to be reduced, but the follow -up innocent treatment's of greatly reduced treatment cost can realize dual economic benefits.
