Abstract

The invention discloses a microorganism metallurgical reactor suitable for an extremely cold environment, and solves the technical problems of prevention a biological oxidation process from being influenced by a weather condition and guarantee of stable production operation under the condition of 30-50 DEG C outdoor temperature in winter. As a heat exchanger, an insulation layer and a sealing cover are added based on a traditional microorganism metallurgical reactor, through a heating effect of the heat exchanger and an insulation effect of the insulation layer and the sealing cover, the guarantee of actuation of the biological oxidation process in the extremely cold environment in winter is realized, and the production work can be stably actuated without being influenced by the seasonal weather condition. The heat exchanger adopts a coil pipe type heat exchanger; and the coil pipe type heat exchanger can achieve the effect of a turbulent plate in the device to realize uniform mixing of pulp, so that the production work is actuated more stably.

Description

technical field [0001] The invention belongs to the technical field of metallurgy and relates to a microbial metallurgical reactor. Background technique [0002] Microbial oxidation is to oxidize certain minerals such as pyrite and arsenopyrite by means of microorganisms, so that the precious metals wrapped in them are exposed for the next oxidation. Factors affecting bacterial oxidation in the microbial oxidation process include suitable temperature, more suitable pH value, uninterrupted air supply, a certain concentration of ore pulp to be oxidized, and nutrient base adjustment; acid gas will also be generated during the biological oxidation process. In view of the above situation, the design of the microbial oxidation reactor should have a temperature adjustment device, a large-area aeration structure, a mixing function, an acid gas collection and treatment concept, and overall anti-corrosion requirements. [0003] However, the biological oxidation process is easily affe...
