The invention discloses a short-process low-cost cyaniding
gold extraction system and a control method thereof, and belongs to the technical field of
precious metal extraction. Gold-bearing ores are fully paved in the leaching
pool, and an alkaline
cyanogen-bearing solution or an environment-friendly
gold extraction agent solution is injected into the leaching
pool. And a drainage
pipe is arranged at the top of the leaching tank and a
drainage ditch is arranged at the bottom. A seepage collection tank, a
sedimentation tank, a
sedimentation tank, a pregnant solution tank and a barren solution tank which are arranged under the
earth surface are excavated and built on one side of the leaching tank, and a
carbon adsorption tank is arranged. The barren liquor returns to the leaching
pool through the
submersible pump and the boiling
slurry making device at regular time, the leaching efficiency is improved, meanwhile, natural layering of coarse ore and fine ore is achieved, the
water content of
cyanide residues obtained after leaching is reduced, and the barren liquor washing effect is achieved. The method is low in
investment cost, short in construction period, short in process, low in production cost and easy to operate, manage and control. In addition, the leaching tank, the
settling tank, the
settling tank and the like are simple in structure, large in volume and capable of obtaining high treatment capacity.
