多年来,我国从事锰业开发利用的科技工作者立足于锰矿资源的特点,在“找富矿、贫变富、深加工”的“九字方针”指引下,经过几十年的艰苦努力,成功研发了许多具有自主知识产权的新工艺、新技术、新材料、新设备,为我国锰业的长期发展打下了坚实的基础,特别是在贫锰矿石深加工方面获得了很大发展。为总结 Over the years, China’s scientific and technological workers engaged in the development and utilization of manganese industry, based on the characteristics of manganese resources, under the guidance of “nine principles” of “looking for rich ore, poor and rich and deep processing”, after decades of hard work , Successfully developed many new technologies, new technologies, new materials and new equipment with independent intellectual property rights, which laid a solid foundation for the long-term development of manganese industry in our country. In particular, great progress has been made in the deep processing of poor manganese ore. To conclude
