Abstract

The invention discloses a production device and a production method of manganese monoxide mineral powder. The production device comprises a reducing furnace which is arranged vertically, wherein an automatic distributor and a loading scraper conveyor; a hot gas nozzle is arranged at the lower part of the reducing furnace; a cooling water tank and a discharge scraper conveyor are arranged at the bottom of the reducing furnace; the loading scraper conveyor is connected with the discharge hole of an intermediate hopper through a first bucket elevator and the feeding hole of the intermediate hopper is connected with a second bucket elevator and a rotary kiln; a bar grizzly is arranged at the feeding hole of the intermediate hopper and a fixed grating is arranged at the discharge hole of the intermediate hopper; and a vibrating screen is arranged on the automatic distributor. The manganese monoxide mineral powder prepared by the production device can be used as a substitute raw material for producing electrolytic metal manganese and electrolytic manganese dioxide; therefore, raw material dependence on manganese carbonate ore in the manganese industry is solved, and acid consumption and cost are greatly reduced.

Description

technical field [0001] The invention relates to a production device and a production method of manganese oxide ore powder, in particular to a device and a production method for producing manganese monoxide ore powder with low-grade manganese oxide ore as raw material. Background technique [0002] Electrolytic manganese metal is widely used in metallurgy, medicine, electronics, communication and other fields. With the development of science and technology, the application of electrolytic manganese continues to expand, and the market demand grows by about 15% annually. The annual production capacity of electrolytic manganese in my country can reach 800,000 tons, accounting for 80% of the world's total production. Over the years, most of my country's electrolytic manganese has been used for export, mainly to Japan, South Korea, Europe and the United States and other countries. Electrolytic manganese metal is obtained from manganese ore by acid leaching to obtain manganese sa...
