在以华主席为首的党中央一举粉碎“四人帮”篡党夺权阴谋的伟大胜利的大好形势鼓舞下,我院冶金室成功地从钴硫精矿浸出液中制取了纯氧化钻,为我国钴资源的开发利用提供了途径。我国钴资源储量丰富,但没有单一的钴矿,多与其他金属共生,原矿品位很低,选矿精矿品位低,冶炼工艺也存在一些问题,因此钴资源一直得不到充分利用。过去我国制造硬质合金所需的钴粉
Inspired by the great victory of the Central Committee of the Chinese Communist Party led by Chairman Hua in smashing the “gang of four” in ushering in the conspiracy to usurp and party ownership, the Metallurgical Laboratory of our hospital successfully obtained pure oxide drills from the cobalt-sulfur concentrate leachate, The development and utilization provides a way. China’s cobalt resources are abundant, but there is no single cobalt ore and many are symbiotic with other metals. The raw ore grade is very low, the concentrate grade is low and the smelting process has some problems. Therefore, cobalt resources have not been fully utilized. In the past our country needed cobalt powder for making cemented carbide
