Abstract: A gold mine cyanide tailing disposal method is provided. The disposal method performs a harmless decyanation treatment on a cyanide tailing slurry obtained from a mineral processing plant, and then performs a resource treatment where a cyanide tailing slurry is subjected to a thickening to obtain a higher concentration. When a backfill is needed, a paste is produced by adding a cementing material after a homogenized stirring of a two-stage horizontal agitator pumped to an underground mining site for filling by a plunger pump. The cementing material is to solidify an underflow and prevent cyanide from being filtered out. When a backfill is not needed, the paste is directly delivered to an open storage area for storing by the plunger pump.
