本文介绍了溶剂萃取、离子交换、电解精炼和区域熔炼等冶金提纯方法在高纯铁制备过程中的应用。
The direct reduced iron is a high-quality material after coldly bonding, and the utilizable value of high-purity iron powder is higher.直接还原铁粉经冷固结成型后即为电炉炼钢的优质原料,而高纯铁粉的利用价值更高。
It is proved that the process of cation reverse flotation is reliable to produce high purity iron concentrate with low silicon content.实践证明阳离子反浮选是生产低硅高纯铁精矿的可靠工艺。
