当矿浆pH值为6.82时，捕收剂用量的变化在两个体系中对磁黄铁矿浮选效果的影响不大；

When the pH value was 6.82 , the change in the collector dosage had little effect on the flotation of pyrrhotite in both systems .

矿浆pH值的变化对矿物可浮性影响较大，两个体系下均是在碱性越强的矿浆中磁黄铁矿的回收率越低，矿浆电位值也随着矿浆pH值增大而降低；

For both systems , the stronger the alkalinity of the pulp , the lower the recovery of pyrrhotite and the pulp potential value was reduced with the increase in pulp pH value .

结果表明，在Ca（OH）2体系中，铁闪锌矿和磁黄铁矿表面都有一个不断被强烈氧化的电极过程，并生成SO42-离子。

The results show that there is a strong oxidized electrode process and SO 2 - _4 ions formation on the surfaces of marmatite and pyrrhotite in Ca ( OH ) _2 system .

结果表明，微波选择性介质加热，可以激励煤中顺磁性黄铁矿FeS2热解，使其转化为非化学计量的磁黄铁矿Fe（1-x）S（0

The results for phase analyses show that the selective dielectric heating of microwave can convert the paramagnetic pyrite in coal to moderately ferro magnetic pyrrhotite Fe_ ( 1-x ) S ( 0

磁黄铁矿的天然可浮性较差，在pH在4.5-6的范围内磁黄铁矿有一定的可浮性，但当矿浆pH值大于8以后它将很难在没有活化剂的条件浮起。

Pyrrhotite has poor floatability . When the pulp pH value range is from 4.5 to 6 , pyrrhotite can be floated partly . But when the pulp pH value is above 8 , pyrrhotite cannot be floated unless activators are used .

新型抑制剂CH-1、CH-2对磁黄铁矿和黄铁矿有很好的抑制作用。

The new depressant CH-1 and CH-2 have great effect on pyrrhotite and pyrite .

磁黄铁矿的Ni、Co、Cu含量与S正相关，说明微量重金属元素与S具有同源的关系，由于地幔去气伴随S而进入下地壳。

Ni , Co and Cu contents in pyrrhotite have a positive correlation with S , indicating that trace heavy metal elements are derived from the same source as sulfur because of degasification of the upper mantle and sulfur entrance into the lower crust .

开发利用Cr2S3等含铬沉淀物相，便于推广应用天然黄铁矿和磁黄铁矿还原Cr（Ⅵ）同时沉淀Cr（Ⅲ）的一步法除铬新工艺。

In order to apply and extend the new technology for one-step treatment of Cr (ⅵ) - bearing wastewater in which Cr (ⅵ) was reduced and Cr (ⅲ) was precipitated simultaneously by natural pyrite and pyrrhotite , we should exploit and apply chromium-bearing precipitate phase .

各种产状的磁黄铁矿中Au、Ag都有一定的含量，其平均值分别为0.19%～0.22%（Au）、0.01%～0.02%（Ag），反映下地壳的麻粒岩化与金矿化的成因联系。

Pyrrhotite in various modes of occurrence contains Au and Ag in some degrees , with averages of 0.19 to 0.22 wt % ( Au ) and 0.01 to 0.02wt % ( Ag ), showing that gold mineralization is genetically related to granulitization of the low crust .

代表性沉积物样品的磁化率-温度（K-T）曲线除了存在580℃磁铁矿的居里温度之外，还显示200~350℃的居里温度，指示样品中存在铁硫化物（胶黄铁矿-磁黄铁矿）。

Representative susceptibility-temperature ( K-T ) curves show 200 ~ 350 ℃ Curie temperature in addition to 580 ℃ of magnetite which reveals the existence of iron sulphide ( greigite or pyrrhotite ) .
