Abstract

The invention discloses a mineral leaching device for membrane bioreactor combined ion exchange. The mineral leaching device comprises a control cabinet, reaction tanks, membranes, an ion exchange column, heating pipes, aeration pipes, a metal ion collector, an eluent control valve, reaction tank slag discharge valves, a nutrient solution storage bottle, a regeneration solution storage bottle and a regeneration control valve. The two sides of the control cabinet are provided with the two reaction tanks respectively; and the membranes, the heating pipes and the aeration pipes are arranged in the reaction tanks. The bottoms of the reaction tanks are provided with the reaction tank slag discharge valves, the bottom of the regeneration solution storage bottle is provided with the regeneration control valve, and a pipeline connected with the ion exchange column and the metal ion collector is provided with the eluent control valve. The mineral leaching device is simple in structure, the influence on mineral leaching caused by factors such as temperature, aeration quantity and leaching chemical environment of the reaction tanks is considered, and the mineral leaching device is novel and reasonable in design, high in working efficiency and very suitable for bio-leaching of mesophilic bacteria and thermophile bacteria.

Description

technical field [0001] The invention belongs to the technical field of biometallurgy, and in particular relates to an ore leaching device with a membrane bioreactor combined with ion exchange. Background technique [0002] In the bioleaching of minerals, a reasonable device is very important both in the laboratory and in the actual application in the field. The rationality should be reflected in the high mineral leaching efficiency, and the temperature, aeration rate, and physical and chemical factors of the reaction tank should all be controlled. Especially when the concentration of leached metal ions in the leaching tank is high, it should be removed in time to eliminate the damage to bacteria in the leaching solution. Existing leaching devices have disadvantages such as poor controllability, inconvenient parameter adjustment, and low leaching efficiency in mineral leaching. Therefore, it is necessary to propose a leaching device that combines a membrane bioreactor with i...
