摘要
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．
Most of the non-ferrous metal mines are associated with one or morecrystal systems of pyrrhotite, of which the treatment feature is different. The variation andrelation between these crystal systems on composition, crystal structure, magnetism andfloatability are studied by means of various test methods in this paper. Results show thatwith the increase of S/Fe ratio in pyrrhotite, the crystal structure of pyrrhotite is changedinto the monoclinic crystal system from the hexagonal one; the magnetism is changed fromweak into strong then to ferromagnetism. Meanwhile, the floatability is strengthened, thatis, the floatability of the monoclinic crystal system pyrrhotite is better than that of thehexagonal one.
