EFFECT OF COAL PYRITE SURFACE OXIDA-TION ON COAL DESULFURATION BY FLOTA-TION AND METHODS OF PYRITE DEPRESSION施秀屏摘 要:<正> This paper discusses the hydrophobicity of the pyrite surface under different extents of oxidation. Experimental results demonstrate that pyrite is floatable only under initial oxidation of its surf ace,while the fresh unoxidized......
