建国以来,我国铁矿地质勘探工作取得了巨大成就,目前无论是铁矿资源的数量还是开采规模,都居世界的前列. 我国铁矿资源最显著的特点是贫矿多,部分铁矿石组份复杂,采、选技术条件复杂,形成许多“呆矿”.初步统计,已生产矿山占有的储量仅占全国总储量的1/4强,占全国已探明工业储量(C级以上)的近1/2,大量的铁矿资源未能
Since the founding of the People’s Republic of China, tremendous achievements have been made in geological prospecting of iron mines in our country, and no matter the number of iron ore resources or the scale of exploitation, the world ranks forefront of the world.Most iron ore resources in China are characterized by a large number of poor ore mines, The complexity of mining, mining, selection of complex technical conditions, the formation of many “dug mine.” Preliminary statistics, production reserves have occupied only 1/4 of the country’s total reserves, accounting for the country’s proven industrial reserves (C and above) Nearly 1/2, a large number of iron ore resources failed
