Weathering type stone coal vanadium ore beneficiation method

The invention discloses a weathering type stone coal vanadium ore beneficiation method; a raw ore bulk density is 1-2g/cm cubic, a specific surface area is 80-110 m2/g, a porosity factor is 45-50%, a Mohs hardness is 2-3, and the raw ore has more than 20% of 0.037mm fraction size. The grinding ore method comprises the following steps: screening the raw ore so as to obtain oversize products and undersize products, crushing the oversize products into granularity 15mm so as to be combined with the undersize products, and the screening particle fraction is 15mm; b, the combined ore material and grinding agent are added in a grinding machine, so granularity 0.074mm ore material can take 55-70wt% of the grinding ore after grinding; c, grading the grinded ore material so as to obtain coarse grain products and fine grain products, wherein the coarse grain products serve as tailings for direct discarding, and the fine grain products serve as vanadium concentrate. The weathering type stone coal vanadium ore beneficiation method improves resource utilization rate, and reduces beneficiation cost.
