Embodiment Construction

[0021] The present invention will be further described below in combination with embodiments.

[0022] The original ore is a weathered low-grade stone coal vanadium mine in Hubei. The recyclable valuable components in the ore are mainly vanadium pentoxide, and the content of vanadium pentoxide in the ore is 0.78%. The raw ore composition of the ore is shown in Table 1 below; the weathering physical characteristics of the raw ore are shown in Table 2 below.

Abstract

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.

Description

technical field [0001] The invention relates to a beneficiation method of weathered stone coal vanadium ore, which belongs to the field of vanadium ore beneficiation. Background technique [0002] The average content of vanadium in my country's stone coal vanadium ore is higher than that in vanadium-titanium magnetite, V 2 o 5 The grade is generally 0.3-1.0%. The reserves of stone coal vanadium ore in my country are 6.7 times that of vanadium-titanium magnetite. Therefore, stone coal vanadium ore is one of the important raw materials for the production of vanadium in my country. However, such vanadium ores used for smelting and extracting vanadium contain V 2 o 5 Generally required to be greater than 0.8%, V 2 o 5 The production of stone coal vanadium ore with a grade lower than 0.8% is basically unprofitable by conventional direct smelting process, and the utilization rate of this part of stone coal vanadium ore is low, resulting in a great waste of resources. Therefo...
