有色金属矿中常伴生一种或多种变体磁黄铁矿，不同变体磁黄铁矿的送别性质不尽相同，本文采取多种测试分析方法，探讨磁黄铁矿的成分变化与晶体结构变化的关系，以及不同变体磁黄铁矿的磁性、可浮性变化的特征．结果表明，随着S／Fe比增大，磁黄铁矿晶体结构由六方晶系演变为单斜品系，磁性则由弱至强直至变为铁磁性．同时，可浮性由差变好，即单斜晶系磁黄铁矿的可浮性优于六方品系磁黄铁矿．
Non-ferrous metal ore often associated with one or more variant pyrrhotite, different variants of pyrrhotic send farewell nature is different, this paper to take a variety of test analysis methods to explore the composition of pyrrhotite and crystal structure The relationship of variation, and the magnetic and flotability changes of different variant pyrrhotites. The results show that as the S / Fe ratio increases, the crystal structure of pyrrhotite evolves from hexagonal to monoclinic, while the magnetism changes from weak to strong to ferromagnetic. At the same time, floatability changed from poor to good, that is, monoclinic pyrrhotic floatability is superior to hexagonal strain pyrrhotite.
