EFFECT OF COAL PYRITE SURFACE OXIDA-TION ON COAL DESULFURATION BY FLOTA-TION AND METHODS OF PYRITE DEPRESSION
摘要
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 or deeply oxidized surface of pyrite is hydrophilic. In the tests an organic reductant C6H3(OH)3 was chosen as the pyrite depressant. It is highly efficient ,and the sulfur in flotation can be significantly improved.
