前言我国的锰矿资源丰富,年产锰盐3万多吨,居世界第五位,产品质量优良,部分锰盐出口,在国际市场上已有一定的影响和声誉。但是与世界先进国家相比,无论在设备、技术以及产量方面差距甚大。仅以电解MnO_2产量为例,目前世界总生产能力约100kt,日本生产能力在60kt以上,我国年生产总量仅约10kt。 Preface China’s manganese ore is rich in resources, with an annual output of more than 30,000 tons of manganese salt, ranking the fifth in the world. The products are of good quality and some manganese exports have a certain influence and reputation in the international market. However, compared with the advanced countries in the world, there is a huge gap in terms of equipment, technology and output. Only the output of electrolytic MnO 2 is taken as an example. At present, the world’s total production capacity is about 100 kt. Japan’s production capacity is above 60 kt. China’s annual production volume is only about 10 kt.
