An ideal processing flowsheet of graphite min-eral from chicheng mine, Hebei Prov. has been pro-posed by studying the mineralogy of graphite and itsflotability. According to the results of close-cir-cuit test, a plant with an annual capacity of 30O0 Tconcentrate was designed. It has been proved byindustral practice that this processing technologyis reliable in operation and obvious in economiceffect. Concentrate grade is up to 87-89% and morethan 87% of recovery under the 3.3% of ore feedgrade. 相似文献
