Embodiment Construction

[0065] The method for producing electrolytic manganese metal by the two-mining method of the present invention is carried out according to the process steps of fine ore grinding, ingredient mixing, leaching, purification, deep purification, and electrolysis. The above-mentioned leaching step includes: using manganese oxide ore as a raw material, pyrite as a reducing agent, mixing two kinds of mineral powders (with a particle size of 100% of 80-130 mesh) with the anolyte according to the ratio, and directly leaching with heating and stirring in a sulfuric acid solution. MnSO 4 , Iron is Fe 2 (SO 4 ) 3 Into the solution. The invention improves the working conditions of workers and creates a way for the development and utilization of low-grade manganese oxide ore and non-ferrous metal ore dressing tailings (pyrite). After years of production tests, the present invention successfully solves the purification and impurity removal technology of manganese sulfate solution, obtains a qu...

Abstract

The invention discloses an improved device and method for producing electrolytic manganese metal by a two-ore method. The method comprises the following steps of leaching, purifying, deeply purifying and electrolyzing; and two ore raw materials for electrolyzing the manganese metal by the two-ore method are low-grade manganese oxide ores and pyrite ores respectively, wherein the low-grade manganese oxide ores are with the manganese content of 15-25%, and the pyrite ores are tailings (the pyrite ores) of the mineral dressing of non-ferrous metal ores or primary ores. The method has the advantages that a product contains C and S, has low impurity and short production flow, is used for deeply purifying a manganese sulfate solution to eliminate the influence of reductive impurities in the solution on the electrolytic process, thereby realizing the normal electrolytic production and improving the quality of products. The method especially creates ways for the development and the utilization of low-grade lean manganese oxide ores and tailings (the pyrite ores) of the mineral dressing of non-ferrous metal ore.

Description

Technical field [0001] The invention relates to the technical field of electrolytic metal manganese devices and methods, in particular to an improved two-ore method for producing electrolytic metal manganese. Background technique [0002] In modern industry, manganese and its compounds are used in various fields of the national economy. Among them, the iron and steel industry is the most important field, which uses 90%-95% of manganese. It is mainly used as a deoxidizer and desulfurizer in the process of ironmaking and steelmaking, and used to make alloys. The remaining 10% to 5% of manganese is used in other industrial fields, such as the chemical industry (manufacturing various manganese salts), light industry (used in batteries, matches, printing paint, soap, etc.), building materials industry (glass and ceramic Colorants and fading agents), defense industry, electronics industry, environmental protection and agriculture and animal husbandry, etc. In short, manganese has a v...
