铁磁性矿物居里点测定的新方法

A new method for determing Curie point of ferromagnetic minerals

本文介绍了一种测试铁磁性矿物居里点的新方法。

A new method for determining Curie point of ferromagnetic minerals is introduced in this article .

结果表明两种岩成土的磁性主要受成土母岩的控制呈弱磁性特征，基本不存在超顺磁性颗粒，表现为不完整反铁磁性矿物的特征。

It is found that the magnetic properties of rock soils were mainly controlled by soil forming parent rock , indicating that the rock soils have low magnetic values .

即使是河床底部缝隙中与砂金相伴沉淀的重砂，由于铁磁性矿物含量较高，与其附近砂石之间存在磁性差异，利用高精度质子磁力仪，也能观测到比较明显的磁异常。

Because the magnetism of the heavy sands nearby the gold placer is stronger than that of the other sands , the magnetic anomalies also can be measured by using high-precision proton magnetometer .

由于硫酸烧渣中的铁属于强磁性矿物，采用湿式鼓筒式弱磁选机分选是较为适宜的。

Fe in the vitriol calcigenous is a high magnetism mineral , so it is feasible to separate Fe by adopting wet drum type weak magnet separator .
