影响镍黄铁矿磁性的因素浅析

The affecting factors of pentlandite magnetism:a brief analysis

磁选试验结果显示,部分镍黄铁矿具有一定的磁性。通过研究发现,镍黄铁矿的磁性与Ni、Fe元素含量高低以及含量的稳定性有一定的关系。相比磁性较弱或无磁性的镍黄铁矿,磁性较强的镍黄铁矿Fe含量相对较高,且Ni、Fe元素含量波动较大。

Magnetic separation test results show that some pentlanditehas certain magnetic properties.It is found that the magnetism of pentlandite have a certain relationship with the content of Ni and Fe elements and the stability of their content.Compared to the weak magnetic pentlandite,the stronger magnetic pentlandite has a higher Fe content,and the content of Ni and Fe elements fluctuates more greatly.
