Abstract

The invention relates to an electrolytic additive free of selenium dioxide for production of electrolytic manganese and a preparation method thereof. The organic additive for production of the electrolytic manganese is characterized by being prepared from the following raw materials in percent by weight: 2-5% of organic sulfide, 6-10% of surfactant, 15-20% of polyethylene glycol and 65-77% of water, wherein the sum of the weight percent of the raw materials is 100%. The organic additive of the invention can be used for replacing the traditional selenium dioxide for the production of the electrolytic manganese, has the characteristics of environmental protection, no toxicity, simple processes and the like, and has higher electrolytic efficiency, low content of selenium impurities in products and high product quality.

Description

technical field [0001] The invention relates to a selenium dioxide-free electrolytic additive for electrolytic manganese production and a preparation method thereof. Background technique [0002] As an important industrial raw material, electrolytic manganese is widely used in the production of high-quality steel, stainless steel, high-strength alloy materials and electronic materials, and has a very important strategic position in the national economy. At the same time, the electrolytic manganese industry is an industrial industry with high resource and energy consumption and heavy environmental pollution. From the perspective of energy conservation and environmental protection, developed countries such as Japan and the United States have shut down existing production enterprises by market and administrative means. At present, only China and South Africa Manganese Metal Corporation (MMC) are producing electrolytic manganese in the world, and my country has become the larges...
