Embodiment Construction

[0021] 1. Mix and stir the vanadium-containing material and slurrying solution to make slurry, the solid-to-liquid ratio is 1:2, and stir for 42 minutes. Preparation method of pulping liquid: add catalyst, oxidant, surfactant and defoamer to water. Stir for 42 minutes to dissolve. Catalysts are oxides, sulfides, etc., oxidants are sodium salts, potassium salts, manganese salts, ammonium salts, etc., surfactants are sulfonates, sodium salts, etc., defoamers are nitrates, phosphates, etc.

[0022] Sodium hydroxide or sodium carbonate and an oxidizing agent (such as hydrogen peroxide, manganese dioxide, sodium salt, potassium salt.) are added to the preparation water of the leach solution and stirred for 47 minutes to dissolve. The content of sodium hydroxide or sodium carbonate is 110g / L, and the content of oxidizing agent (such as hydrogen peroxide, manganese dioxide, sodium salt, potassium salt.) is 11g / L.

[0023] Stir and heat the prepared slurry of vanadium-containing mat...

Abstract

The invention discloses a production process technology of ammonium vanadate (the ammonium vanadate in the patent refers to ammonium metavanadate, ammonium polyvanadate and the like), and the production process technology is an ammonium vanadate production process of extracting vanadium from vanadium-containing minerals, recovering vanadium from vanadium-containing catalysts and recovering vanadium from various solid wastes of metallurgical hazardous wastes and belongs to the technical field of smelting extraction, high-valued treatment of hazardous waste recovery and high-valued treatment ofsolid waste recovery. The production process technology is characterized in that no wastewater is generated in the ammonium vanadate production process, the process technical route of generating a large amount of wastewater in the traditional production process is completely changed, the production cost and the potential pollution of production to the environment are greatly reduced, and the technology is a brand new ammonium vanadate production process with simplified production process, high recovery rate, large capacity, energy conservation, environmental protection, zero emission and environmental friendliness. The production process technology can also be used for extracting low-content vanadium ore, and in the production process of a traditional vanadium extraction process, extraction cannot be further carried out when the content of vanadium pentoxide in a vanadium-extracted waste slag material is 1-3%; and the production process technology can be used for extracting the low-content vanadium ore and recycling vanadium ore tailings and the waste slag material after smelting, and the recovery rate can reach 95%.

Description

technical field [0001] A kind of technical field of the production method of ammonium vanadate (comprising ammonium metavanadate and ammonium polyvanadate etc.) [0002] The technical field of a method for producing ammonium vanadate (including ammonium metavanadate and ammonium polyvanadate) belongs to the technical field of smelting extraction, high-value treatment of hazardous waste recovery and high-value solid waste recovery. [0003] technical background [0004] Ammonium vanadate (including ammonium metavanadate and ammonium polyvanadate, etc.) is the main raw material for the production of vanadium pentoxide and other vanadium products. [0005] At present, the production process of ammonium vanadate salt (including ammonium metavanadate and ammonium polyvanadate, etc.) in the world is divided into acid leaching production process and alkaline leaching production process. At present, the production process of ammonium vanadate salt has high production cost, because T...
