摘要

本文主要是运用第一性原理对白铁矿、黄矿铁和磁黄铁矿的电子结构进行计算,并分析这三种硫铁矿的电子结构的差异所造成的可浮性差异。而研究结论表明:白铁矿、黄铁矿和磁黄铁矿分别为间接带隙半导体、自带隙半导体和道导体。而通过态密度研究也表明,白铁矿与黄铁矿属于低自旋态,磁黄铁矿属于自旋一极化态。
        This paper is mainly using first principles of white iron ore,yellow ore iron and pyrrhotite electronic structure calculation,and analysis caused by differences in the electronic structure of these three kinds of pyrite flotability differences.The research results show that:the white iron ore,pyrite and magnetic pyrite are indirect band gap semiconductor,self- gap semiconductor and conductor.And the study of the density of states shows that the white iron ore and pyrite belong to the low spin state,and the magnetic pyrite is a spin polarized state.
