Pyrrhotite is an associated mineral that exists widely in sulfide ore. The presence of pyrrhotite will affect the recovery of platinum group minerals. Therefore, researchers have paid increasing attention to the flotation separation of pyrrhotite. Pyrrhotite superstructures owning different Fe/S ratios results in various crystal structures, corresponding to different physical, chemical and electronic properties, and consequently different flotation behavior. In the present paper, a comprehensive review is conducted to discuss the influence of crystal structures on the natural floatability, mineral-reagent interaction, surface oxidation and flotation electrochemistry of pyrrhotite. The selective flotation process of pyrrhotite from its associated minerals is also reviewed in this paper. It is hoped that this review can summarize the newly published research results combined with some representative results from the past, to provide a theoretical basis for the study of the flotation mechanism of pyrrhotite and provide a new direction for future research on pyrrhotite.

磁黄铁矿是一种伴生矿物，广泛存在于硫化矿中。磁黄铁矿的存在会影响铂族矿物的回收率。因此，研究人员越来越重视磁黄铁矿的浮选分离。磁黄铁矿超结构具有不同的Fe/S比，会产生不同的晶体结构，对应不同的物理、化学和电子特性，从而产生不同的浮选行为。本文综合综述了晶体结构对磁黄铁矿天然可浮性、矿物-试剂相互作用、表面氧化和浮选电化学的影响。本文还对磁黄铁矿伴生矿物的选择性浮选工艺进行了综述。
