Abstract

The invention discloses a method for extracting manganese from composite manganese ore composed of multiple phases containing manganese. The method provides a new technology for processing novel manganese resources. The method includes the specific steps that the composite manganese ore is smashed and ground, and composite manganese concentrate is obtained through a magnetic separation method; then the composite manganese concentrate is placed in a roasting device, roasting temperature ranges from 200 DEG C to 600 DEG C, roasting time ranges from 1h to 4h, an obtained roasted product is leached through sulfuric acid, the weight ratio of added sulfuric acid to the roasted product is 2-10 to 1, leaching temperature ranges from 30 DEG C to 100 DEG C, leaching time is 30-240 min, filtering is carried out, the leached liquid is deironized, then sodium fluoride is added to remove calcium and magnesium, then co-precipitation is carried out for further impurity removal, the obtained filtered liquid is conveyed into an electrolytic cell to be electrolyzed, and an electrolytic metal manganese product is obtained. The method has the advantages of being high in reaction efficiency, high in speed, capable of reducing energy consumption and saving resources, high in product recovery rate and environmentally friendly.

Description

technical field [0001] The invention relates to a method for extracting metal manganese from manganese ore, in particular to a method for extracting manganese from composite manganese ore composed of manganese-containing multi-phase. Background technique [0002] Electrolytic manganese metal is widely used in metallurgy, medicine, electronics, communications and other fields, and is an indispensable and important substance in modern industry. With the development of science and technology, the application of electrolytic manganese continues to expand, and the market demand increases by about 15% annually. At present, the main method of producing electrolytic manganese metal in my country is to use manganese carbonate ore or sintered manganese ore as the main ore, and use manganese dioxide ore to remove iron to produce electrolytic manganese metal. Due to the limited resources of manganese carbonate ore in China, and the grade is decreasing year by year, coupled with the exi...
