会议由冶金部科技司于1991年3月在吉首市召开,有22个单位的46名代表参加。与会专家对长沙矿冶研究院等单位完成的强磁一锰精矿烧结—熔炼—脱磷(即炉外脱磷法)和马鞍山矿山研究院等单位共同完成的强磁—沸腾焙烧—酸浸(即黑锰矿法)两个连续扩大试验进行了技术鉴定。认为:①两种方法均可作为工业试验的依据,建议尽快组织进行,以便加快大规模开发利用。②炉外脱磷法工艺简单,环境治理易于解决,无
The meeting was held by the Ministry of Science and Technology of the Ministry of Metallurgy in Jishou City in March 1991 with 46 representatives from 22 units participating. Participants at the Changsha Mining and Metallurgical Research Institute and other units completed a strong magnetic manganese ore sinter - smelting - dephosphorization (ie furnace dephosphorization) and the Ma On Shan Institute of Mining and other units jointly completed by the strong magnetic - boiling roasting - acid leaching (Ie, black manganese ore method) two continuous expansion of the technical appraisal. That: ① The two methods can be used as the basis for industrial tests, it is recommended to organize as soon as possible, in order to speed up the development and utilization of large-scale. ② furnace dephosphorization process is simple, easy to solve environmental management, no
