Abstract

The invention discloses a method for preparing foamed ceramic by using vanadium ore tailings as a main material, which is characterized in that the foamed ceramic is prepared by using the vanadium ore tailings as the main material and a conditioner as an auxiliary material through mixing and powdering, granulating and sintering processes. According to the method, the vanadium ore tailings serve as the main material, the conditioner is added to prepare the foamed ceramic, the foaming uniformity degree is guaranteed, meanwhile, the strength and quality of the foamed ceramic are improved, the prepared foamed ceramic product meets the national standard requirement, the doping amount of the vanadium ore tailings is increased, utilization of the vanadium tailings is achieved, and the comprehensive treatment problem of the vanadium tailings is solved; the problems of high mixing energy consumption and high water consumption of a traditional preparation method are solved, energy and water are saved, and the preparation cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of tailings, and in particular relates to a method for preparing foamed ceramics by using vanadium ore tailings as a main material. Background technique [0002] At present, sodium roasting of vanadium ore is the mainstream process for vanadium extraction. This process uses soda ash, table salt, etc. as additives to convert low-valent vanadium in vanadium ore into water-soluble pentavalent vanadate sodium salt through high-temperature sodium oxidation. Vanadium chemical products such as vanadium oxide and vanadium alloy are produced through subsequent product transformation. However, for a long time, the traditional vanadium chemical metallurgical process has produced a large amount of solid waste, mainly vanadium ore tailings after vanadium extraction. The vanadium ore tailings alone reach nearly one million tons every year, and it is increasing year by year. Due to the lack o...
