Ore pulp electrolysis continuous leaching device

Abstract

The invention discloses an ore pulp electrolysis continuous leaching device, and relates to the field of hydrometallurgical equipment. The ore pulp electrolysis continuous leaching device comprises a square electrolytic cell main body, an anode region, a cathode region and a conical cell bottom, the anode region and the cathode region are separated by a percolation diaphragm, the cathode region communicates with the conical cell bottom, the conical cell bottom is provided with a spiral material collecting device, the bottom of the anode region is provided with a porous air charging device, the upper side faces of the cathode region and the anode region of electrolytic cells are provided with feed ports, the opposite side faces are provided with overflow ports, the overflow ports are connected with overflow pipes, the plurality of electrolytic cells are sequentially connected in a trapezoidal manner from high to low through the overflow pipes, so that an electrolysis system with multiple stages of electrolytic cells connected in series is formed. Ore pulp enters the first-stage electrolytic cell after being mixed, is electrolyzed in series through the plurality of electrolytic cells and is discharged from the overflow ports of the tail-stage electrolytic cell; and metal mud in the cathode area falls into a conical cell bottom collecting area, the spiral material collecting device feeds the cathode mud into a pipeline, the metal mud is obtained through solid-liquid separation, and electrolyte returns to the electrolysis system; and the device is convenient for collecting the metal cathode mud and realizes continuous operation.

Description

technical field [0001] The invention discloses an ore pulp electrolysis continuous leaching device, which relates to the field of hydrometallurgical equipment. Background technique [0002] Slurry electrolysis process is a new hydrometallurgical technology. At present, slurry electrolysis has been widely studied in the fields of processing chalcopyrite, galena, complex silver concentrate, bismuth ore, polymetallic sulfide ore, etc., among which breakthroughs have been made in the treatment of bismuth ore, complex silver concentrate and gold concentrate , have achieved industrial production. Its unique advantages of high efficiency and environmental protection make pulp electrolysis have broad application prospects. [0003] The principle of slurry electrolysis is as follows: After the finely ground minerals are slurried, they are added to the anode area of ​​the electrolytic cell, and the appropriate electrolyte is selected according to different minerals. The metal miner...

Problems solved by technology

The same is that the leached valuable metals are stored in the diaphragm frame in the slurry electrolytic cell. If you want to take out the valuable metals, you can only take out the cathode plate and shovel the cathode mud or pour the metal mud from the diaphragm bag. One is troublesome, the labor intensity of workers is high and the efficiency is low, and the electrolyzer cannot work continuously
