Abstract:
      Pyrite is a widely-existing metal sulfide ore, and its flotation problem has always been a research hotspot in the field of mining engineering. Flotation practice shows that there are differences in floatability between pyrites of different genesis, mainly due to differences in mineralogical factors. Small changes in the mineralogical factors of pyrite may have different effects on their flotation behavior. For example, the pyrite lattice defects will enhance or reduce the floatability by changing the adsorption characteristics of the mineral surface. In this paper, the effects of lattice defects, physical properties and chemical composition on the floatability of pyrite are analyzed,and the general regularity between mineralogical factors and the floating characteristics of pyrite is discussed. The purpose of this paper is to cause the mineral processing workers to pay attention to mineralogy factors and provide a theoretical reference for the practice of pyrite flotation.
