AI Technical Summary

Technical Problem

In the leaching process of the existing stirred cyanide method, the recycling efficiency of activated carbon is low and is easily crushed during the high-speed rotation, resulting in a decrease in the effective volume of the leaching tank and a decrease in the leaching operation efficiency.

Method used

Leaching equipment that adopts Venturi circulation ore feeding method, drives the gears and rods to rotate through the motor, and rotates the recycling plate and scraper, pushes the activated carbon to the recovery valve, and brings air into the Venturi circulation pump to make the ore slurry float, precious metals The activated carbon on the upper part of the leaching tank is highly adsorbed.

Benefits of technology

The recycling efficiency and leaching operation efficiency of activated carbon are improved, damage and accumulation of activated carbon are avoided, and the effective volume of the leaching tank is increased.

Abstract

The invention discloses leaching equipment adopting a Venturi circulating ore feeding mode and a using method, and belongs to the technical field of leaching equipment. The adsorption mechanism comprises a supporting part, a storage part, a rotating part and a collecting part, a recovery plate is adjusted to rotate along a conveying cylinder, activated carbon in the adsorption mechanism is pushed to an activated carbon recovery valve, a lower partition plate is driven to rotate through a connecting rod in the rotating part, and the activated carbon is driven to move; activated carbon adsorbing gold complexes can be efficiently recycled, an agent feeding pipe is opened to feed an agent while a circulating pump is opened to fill ore pulp, by arranging a Venturi circulating mechanism, the ore pulp moves in an accelerated mode under the action of the Venturi effect, a large amount of air is brought in, the ore pulp entering a leaching tank floats upwards under the action of the air, and the gold complexes are leached out. The precious metal gold is finally captured by the activated carbon in the adsorption mechanism on the upper portion of the leaching tank, the activated carbon fully adsorbs the precious metal through cooperation of the rotating component, and the leaching operation efficiency is improved.
