Abstract

The invention relates to a method of preparation, in particular to a method for realizing the vanadium enrichment by the physical method of preparation before the chemical vanadium extracting process of the stone coal vanadium ore. The technical proposal comprises the following: step one, choosing the stone coal vanadium ore and crushing equipment, and crushing the stone coal vanadium ore by the crushing equipment; step two; finishing the first gradation, and separating out the coarse fraction ore and discarding ore tailings; step three; finishing the second gradation, and separating out finefraction ore and directly obtaining the refined ore; and step four, enriching vanadium in the middle-level ore obtained from two gradations by the selective grinding-floatation method so as to obtainthe floatation foam refined ore and the in-slot ore tailings. The method has the advantages of 1, reducing the investment cost for building a vanadium extracting factory and the production cost for vanadium extraction; 2, reducing the consumption of the materials and the tailings needed for extracting each ton of vanadium, and further reducing the 'three wastes' pollution during the vanadium extraction; and 3, facilitating the use of the environmental protection process with high investment which replaces the conventional sodium method roasting process in the stone coal vanadium extraction industry, and fundamentally solving the problem of the 'three wastes' pollution.

Description

technical field [0001] The invention relates to a beneficiation method, in particular to a method for realizing vanadium enrichment by using a physical beneficiation method before the chemical vanadium extraction process of stone coal vanadium ore. technical background [0002] Vanadium resources and reserves are mainly symbiotic in vanadium-titanium magnetite and stone coal mines. Stone coal mines are low-grade vanadium-containing resources. Except for China, there are few other countries in the world that exploit and utilize them industrially. Stone coal is a low-quality coal with low carbon content and low calorific value. It is a low-grade, polymetallic paragenetic ore. Alum mainly exists in the ore phases such as vanadium-containing mica, illite, and vanadium-containing kaolinite. my country has extremely rich reserves of stone coal vanadium resources, mainly distributed in more than 20 provinces such as Hunan, Hubei, Sichuan, Guizhou, Zhejiang, Guangxi, Jiangxi, Anhui...
