Double helix pipe reactive tank ore pulp gas circulation device

Abstract

The invention discloses a double helix pipe reactive tank ore pulp gas circulation device which comprises a tank body. An air pipe is arranged in the tank body, helix pipes are arranged on the two sides of the air pipe, the lower ends of the helix pipes are connected with a collecting cover, circulation bends are arranged above the helix pipes, the height of the lower end of the air pipe is smaller than that of the lower ends of the helix pipes, the lower end of the air pipe is arranged at the upper portion of the collecting cover, the upper end of the air pipe is connected with an air compressor through a pipe, the pipe is provided with a gas flowmeter and a regulating valve, and the number of the helix pipes is two. The double helix pipe reactive tank ore pulp gas circulation device hasthe advantages that compression air is supplied in so that ore pulp flows in a circulated manner, activated carbon, oxygen and an agent are driven to be sufficiently mixed, losses of the activated carbon are reduced, the oxygen is supplemented, and the leaching efficiency is improved. The equipment is simple in structure, convenient to maintain and replace and free of mechanical noise.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, in particular to an ore slurry gas circulation device. Background technique [0002] The reaction tank is an indispensable device for carbon slurry metallurgy. In the leaching tank, the gold in the slurry reacts with sodium cyanide and oxygen to form gold ions that are easily adsorbed by activated carbon. The traditional device uses a motor to mechanically stir the pulp, so that the pulp in the leaching tank maintains a certain concentration, and accelerates the gold leaching speed and the adsorption rate of activated carbon. During the stirring process, a large number of activated carbon particles will be broken by the stirring fan blades, resulting in the loss of the amount of carbon, and a part of the powdered carbon adsorbed on gold will enter the tailings and cannot be recovered, resulting in huge economic losses. Generally, the carbon slurry process requires larger and more leac...

AI Technical Summary

Problems solved by technology

The motor stirring device has been in a corrosive environment for a long time, resulting in a large amount of maintenance for workers

In order to prevent the diffusion of sodium cyanide, the leaching tank is closed. Just stirring cannot meet the oxygen required for the reaction, and an additional aeration device is required.

And the mechanical stirring is accompanied by noise, which is harmful to the workers' health
