摘要
随着铁矿资源的进一步开发,如何脱除高硫铁精矿中的硫、提高铁精矿质量越来越受到人们的重视。以往铁精矿脱硫普遍使用大量硫酸和硫酸铜进行活化,硫酸用量大不但在生产过程中严重腐蚀设备,而且对工作环境影响很大,特别是多金属矿石的选别,浮选过程往往加入大量的石灰,将对摇床的结垢的变形产生严重的影响。本文从磁铁矿和磁黄铁矿的分选流程和药剂制度两个方面分析了铁精矿脱硫的方法,并对云南文山某磁铁精矿进行浮选脱硫试验研究发现:用Na2S+CuSO4活化脱硫比硫酸和硫酸铜活化脱硫效果好,硫的脱除率提高%。
As the further exploitation of iron ore resources, peolpe are paying more and more attention on how to utilize the ore resources fully and how to remove the sulfur from iron ore. The article describes the principles and techniques simply about removing sulfur from iron ore. Then it introduces a producing practice about removing sulfur from the iron ore. The author emphasizes that flotation is an ordinary and effective way to separate magnetic pyrite from magnetite, and selecting the fight technical process and reagent regime is critical for flotation.
