Biological oxidation gold extraction microwave processor

Abstract

The invention discloses a biological oxidation gold extraction microwave processor. A driven gear ring is arranged on the outer wall of a roller, two bearings are vertically embedded in the centers oftwo sides of the roller, a microwave processing device is installed in each bearing, support plates with the same length are vertically connected to shells of the microwave processing devices, a flatplate-shaped base is vertically arranged at the bottom of each support plate, motors are installed on the top surfaces of the bases, a driving gear is installed on an output rotating shaft of each motor, and the driving gears are engaged with the driven gear ring; and each microwave processing device comprises a microwave generator, wherein the microwave generator is arranged at the axial end part of the roller and communicates with the interior of the roller. The biological oxidation gold extraction microwave processor can make metal concentrate turn over for uniform microwave treatment, sothat the metal concentrate is subjected to microwave treatment more uniformly, and the yield of biological oxidation gold extraction is improved.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular, the invention relates to a microwave processor for biological oxidation gold extraction. Background technique [0002] Bio-oxidation gold extraction technology is to use ore leaching microorganisms to oxidize and decompose metal sulfides, and enter the liquid phase in the form of soluble sulfates. The gold ore after oxidation pretreatment is then dissolved and recovered with a gold leaching solvent. After the main polluting element arsenic in the ore enters the liquid phase in the form of ions, it is then neutralized by the lime iron salt method to form a stable iron arsenate precipitate, which can be discharged up to the standard and will not pollute the environment. During the bio-oxidation gold extraction process, it is necessary to add microwave additives to the metal concentrate, and then use a microwave processor for microwave treatment.

Chinese Patent Application No. 201410628726.X discloses a method of oxidative roasting-microwave-assisted leaching of high-arsenic gold-containing sulfur concentrate, which only mentions "recombining 10g of high-arsenic gold-containing sulfur concentrate after roasting and preparing A good thiosulfate solution is mixed according to a solid-to-liquid ratio of 1:2 to 3, and the unit is g / mL, and placed in a microwave device", but the specific structure of the microwave device is not disclosed; in addition, the existing biological Oxidation gold extraction microwave processor is designed in a traditional way. During microwave treatment, the metal concentrate cannot be turned over for uniform microwave treatment. The treatment effect is not good, which affects the output of biological oxidation gold extraction.
