Abstract

The invention discloses a comprehensively-utilizing process of waste residue containing vanadium, molybdenum, nickel and cobalt, which is characterized in that the process flow comprises the steps of crushing and grinding crude nickelferrite, carrying out acid leaching by oxygen pressure, comprehensively recovering the vanadium and the molybdenum from leached residue, removing ferrite, copper, silicon and aluminum in the leaching liquid, deeply removing impurities by P204 extraction, separating nickel and cobalt by P507 extraction, electrolyzing and deposing the nickel and deposing cobalt carbonate. The acid leaching by oxygen pressure is carried out in a pressure kettle and oxygen instead of nitric acid is introduced during leaching. The acid leaching by oxygen pressure comprises the following steps of: mixing size and pre-leaching, adding water and crude nickelferrite powder into a size mixing tank, stirring the calculated sulfuric acid and mixing into size; and inputting the mixed size into the pressure kettle by a size mixing pump, introducing oxygen for acid leaching by oxygen pressure, filtering and washing after leaching, carrying out reverse flow washing on the leached residue for three times and using washed water returned for mixing size as a supplemented preparation solution; and recovering vanadium and the molybdenum from the washed leached residue. According to the technical scheme, small testes and semi-industrial tests are finished and achieve favorable effects, a production workshop capable of annually producing 1,000t/a of electrolytic nickel and 434t/a of CoCo3 is established and is presently converted into production after debugging and trial production. Compared with the prior art, the invention obtains remarkable effect.

Description

1. Technical field [0001] The invention relates to a comprehensive utilization process of waste residue containing vanadium, molybdenum, nickel and cobalt. 2. Background technology [0002] More than 200,000 tons of vanadium extraction waste slag are produced in Panxi area every year. The vanadium content in the waste tailing slag is generally 0.8-1.2%, and it also contains valuable metals such as molybdenum. The residual non-ferrous metals in the tailings have high comprehensive utilization value. Petroleum industry at home and abroad will produce a large amount of waste aluminum-based molybdenum catalyst (commonly known as: oil residue) in the process of crude oil desulfurization treatment. It is a good polymetallic extraction raw material with high comprehensive utilization value. More than 100,000 tons of such waste catalysts are produced in the world every year. Due to the insufficient development and utilization of such raw materials for many years, there are current...
