Embodiment Construction

[0007] The present invention is specifically described below in conjunction with accompanying drawing, as figure 1 As shown, it includes a tank body 1, an air pipe 3 is arranged in the tank body 1, and a spiral pipe 2 is arranged on both sides of the air pipe 3; Pipe 4; the height of the lower end of the air duct 3 is lower than the height of the lower end of the spiral pipe 2; the lower end of the air duct 3 is arranged on the upper part of the collection cover 8; the upper end of the air duct 3 is connected with the air compressor 7 through a pipeline; Flow meter 5 and regulating valve 6.

[0008] The present invention uses an air compressor to compress the air, so that high-pressure air enters the bottom of the pulp in the reaction tank, and the high-pressure air makes the local pulp concentration smaller, and the surrounding pulp compresses this part, so that the local pulp rises into the circulation elbow, and then the pulp circulates in the entire reaction tank flow.

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...
