| titleOfInvention | A kind of method utilizing nickel-molybdenum ore to prepare barium molybdate |
| abstract | The present invention relates to a kind of method utilizing nickel-molybdenum ore to prepare barium molybdate, belong to the technical field of nonferrous metallurgy.The method comprises the following steps: a, by nickel-molybdenum ore pulverize after, oxidizing roasting decompose desulfurization, obtain calcining; B, calcining and sodium agent are mixed after, carry out sodium roasting, obtain sodium material, then soak sodium material, filter, obtain sodium molybdate solution and water-fast nickel slag respectively; C, sodium molybdate solution is added cleaner purification and impurity removal after, add acid, filter, obtain precipitate molybdic acid thing and filtrate respectively; D, precipitate molybdic acid thing sodium hydroxide solution dissolve, and filter, obtain the pure sodium molybdate solution that molybdenum concentration is 150 ~ 210g/l; E, by sour adjust pH to 2 ~ 3.5 of pure sodium molybdate solution, under the condition of 20 DEG C ~ 60 DEG C, add precipitation agent and stir, being settled out barium molybdate, dry after filtering, to obtain final product.The invention has the beneficial effects as follows: can reduce costs, not pollute the environment, gained barium molybdate is superior in quality. |
