Embodiment 1

[0019] Put the collected one ton of manganese ions in the processing pool, add 40 kg of sodium hydroxide, stir evenly, let it stand for 12 hours to make it fully react; take it out and rinse it, then add 50 kg of sodium hydroxide to the processing pool Add oxalic acid while stirring, take it out after 10 minutes of reaction, rinse it with clean water, and immediately put it into the oven for baking. The chemical index analysis, before adopting the inventive method to process, the Mn content in the tank manganese ion is 89.51%, and the S content is 0.12%, and the S content is obviously superhigh, and after the treatment, the Mn content is brought up to 93.62%, and the S content is reduced to 0.032%, a substantial reduction.

Embodiment 2

[0021] Put the collected manganese ions of one ton in the treatment pool, add 50 kg of sodium hydroxide, stir evenly, let it stand for 10 hours to make it fully react; take it out and rinse it, then add 55 kg of sodium hydroxide to the treatment pool Dilute hydrochloric acid, stir while adding, take out after 8 minutes of reaction, rinse with clean water, and immediately enter the oven to bake. The chemical index analysis, before adopting the method of the present invention to handle, the Mn content in the tank manganese ion is 88.87%, and the S content is 0.118%, and the S content is obviously superhigh, and after the treatment, the Mn content is brought up to 94.13%, and the S content is reduced to 0.036%, a substantial reduction.

[0022] The amount of alkaline substances added to the treatment pool, such as sodium hydroxide, potassium hydroxide, calcium hydroxide, etc., can also be 20, 25, 30, 35, 40, 60, 65, 70, 75, 80 kg per Manganese ions per ton of tank; the acidic so...

Abstract

The invention discloses a method for removing and processing impurities in manganese ions generated by a negative plate of electrolytic manganese. The method comprises the steps of: 1. collecting the mangeanese ions generated during the electrolytic process, screening the mangeanese ions by a vibrating screen, and then putting the manganese ions into a treating pond and adding water; 2. adding alkali matters into the treating pond, adding the mangeanese ions with the amount of 20-80kg / ton, stirring completely and then standing; and 3. washing the mangeanese ions, putting the manganese ions into the treating pond and adding clear water; also adding diluted hydrochloric acid, oxalic acid and the like into the treating pond, and stirring simultaneously; adding the mangeanese ions with the amount of 20-70kg / ton; and taking out the mangeanese ions again, using clear water to wash, and entering an oven for roasting immediately. The processing method can effectively remove the impurity sulfur in the mangeanese ions, reduce the content of sulfur to lead the product to conform to the related standard so as to become a qualified product, fully utilize manganese resources, reduce electric energy consumption and consumption of other auxiliary materials, effectively decrease the smelting cost of electrolytic manganese, meet the requirements of energy saving and energy reduction of enterprises, and reduce the discharge of wastes.

Description

technical field [0001] The invention relates to a treatment method for tank manganese ions produced at the edge of a cathode plate during electrolytic manganese production, in particular to a treatment method for removing sulfur-containing impurities in the tank manganese ions. Background technique [0002] During the production process of electrolytic manganese, manganese ions are electrolytically adsorbed on the cathode plate to become metal manganese; and at the edge of the cathode plate, a flocculent electrolytic substance rich in manganese is produced, which is called “slot manganese ion” in the industry. The manganese ions in the flocculent tank fall off the cathode plate combination frame, half float in the electrolytic solution, and are oxidized and blackened due to being soaked in the solution for a long time, mainly because of the high sulfur content (the sulfur content can reach 0.1%~ 0.2%) and anode slag and other impurities can not be used as qualified manganese...
