Embodiment Construction

[0065] The method for producing the electrolytic metal manganese by the two-mine method of the present invention is carried out according to the process steps of: ore fine grinding, ingredient mixing, leaching, purification, deep purification and electrolysis. The above-mentioned leaching steps include: using manganese oxide ore as raw material, pyrite as reducing agent, mixing two kinds of ore powders (100% particle size is 80-130 mesh) with anolyte according to the proportion, directly heating and stirring in sulfuric acid solution for leaching, manganese MnSO 4 , iron in the form of Fe 2 (SO 4 ) 3 into 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 ore). After years of production tests, the present invention successfully solves the purification and impurity removal technology of manganese sulfate solution, and obt...

Abstract

A method for producing electrolytic manganese metal by using two ores and apparatus thereof are disclosed. The method comprises the following steps: leaching in sulfuric acid (5), purifying to remove iron (7), deeply purifying (18) and electrolyzing (25). The two ores are manganese oxide ore (1) containing 15~25% of Mn, and tailing pyrite (2) from non-ferrous metal ores dressing or primary pyrite (2). The apparatus comprises: milling device, leaching device, pressure filtering device, sulfurizing tank, purifying tank, deeply purifying tank, settling tank, air compressor, mixing kettle and electrolytic tank. The method and apparatus produce manganese sulfate solution meeting the requirement of electrolysis, thereby stabilizing electrolysis production and improving the quality of products.

Description

technical field [0001] The invention relates to the technical field of devices and methods for electrolytic manganese metal, in particular to a device and method for producing electrolytic metal manganese by an improved two-mine method. 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, and the amount of manganese used accounts for 90% to 95%. 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 chemical industry (manufacturing various manganese-containing salts), light industry (used in batteries, matches, printing paint, soap making, etc.), building materials industry (glass and ceramics) colorant and fading agent), defense industry, electronics industry, as well as environmental...
