METHOD FOR THE PURIFICATION OF ALUMINA

Digestion of impure alumina with sulfuric acid dissolves all constituents except silica. The resulting sulfates—aluminum sulfate, ferric sulfate, titanyl sulfate, and magnesium sulfate for alumina contaminated with iron-, titanium-, and/or magnesium-containing species—remain in solution at approximately 90° C. Hot filtration separates silica. Solution flow over metallic iron reduces ferric sulfate to ferrous sulfate. Controlled ammonia addition promotes hydrolysis and precipitation of hydrated titania from titanyl sulfate that is removed by filtration. Addition of ammonium sulfate forms ferrous ammonium sulfate and ammonium aluminum sulfate solutions. Alum is preferentially separated by crystallization. Addition of ammonium bicarbonate to an ammonium alum solution precipitates ammonium aluminum carbonate which may be heated to produce alumina, ammonia, and carbon dioxide. The remaining iron rich liquor also contains magnesium sulfate. The addition of oxalic acid generates insoluble ferrous oxalate which is thermally decomposed to ferrous oxide and carbon monoxide which is used to reduce the ferrous oxide to metallic iron. Further oxalic acid addition precipitates magnesium oxalate which is thermally decomposed to magnesium oxide. 1.

Ilmenite concentrate processing method

FIELD: production technology. SUBSTANCE: invention can be used in processing natural titanium-containing material to obtain anatase modification titanium dioxide. Ilmenite concentrate processing method involves its exposure by means of a sulphatising reagent with subsequent separation of titanium compounds from iron compounds. Opening is carried out in solid phase by roasting concentrate with excess of ammonium sulphate as sulphatising reagent at 360–400 °C for 4.0–4.5 h. Formed product is leached with water at ratio T:I = 1:5.0–5.5 to obtain a solution containing iron and titanium sulphates. Insoluble residue is separated. Thermal hydrolysis of the obtained solution is carried out at 80–90 °C for 1.5–2.0 h. Titanium dioxide is obtained in form of a fine crystalline sediment of anatase modification, which is settled for 2–3 hours, separated from the solution by filtration and dried. After extraction of titanium dioxide solution is used to produce iron syrup. EFFECT: invention increases efficiency of processing ilmenite concentrate while improving environmental safety and reducing harmful effects on the human body by reducing the number of steps, performing opening in a solid phase, eliminating the use of sulfuric acid. 4 cl, 3 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 715 193 C1 (51) МПК C01G 23/053 (2006.01) C22B 34/12 (2006.01) C22B 1/06 (2006.01) C22B 3/04 (2006.01) C01G 49/14 (2006.01) C01C 1/242 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК C01G 23/0532 (2019.08); C22B 34/1204 (2019.08); C22B 34/1236 (2019.08); C22B 1/06 (2019.08); C22B 3/04 (2019.08); C01G 49/14 (2019.08); C01C 1/242 (2019.08) (21)(22) Заявка: 2019104828, 20.02.2019 20.02.2019 Дата регистрации: Приоритет(ы): (22) Дата подачи заявки: 20.02.2019 (45) Опубликовано: 25.02.2020 Бюл. № 6 2 7 1 5 1 9 3 R U (54) Способ переработки ильменитового концентрата (57) Реферат: Изобретение может быть использовано при переработке природного ...

从含二氧化钛的原料，如富含TiO 2 的钢炉渣中回收二氧化钛的方法，包括以下步骤：研磨二氧化钛原料，使该颗粒状原始进料与硫酸在规定条件下反应，溶解和过滤含有硫酸氧钛的所得饼状物，水解硫酸氧钛，以及在洗涤水解产物后，煅烧该水解产物，以获得二氧化钛。

Titanium dioxide nacreous pigments and process for the preparation thereof

Nacreous pigments comprising crystalline TiO2 platelets, either supported on corresponding plate-like calcium sulfate anhydrite particles or self-supporting. The pigments are prepared by depositing amorphous TiO2 coatings on plate-like gypsum substrate particles, calcining the resulting product to convert the gypsum to the anhydrite and crystallize the TiO2 and, when an unsupported pigment is to be produced, dissolving out the anhydrite substrate. The crystalline TiO2 is produced in the form of either rutile or anatase.

Method for comprehensively utilizing titanium white waste acid

本发明公开了一种钛白废酸综合利用的方法，涉及钛白废酸综合回收利用及非高炉钛渣直接生产硫酸法钛白的方法，属于钛白非酸处理技术领域。本发明用钒钛磁铁矿直接还原钛渣作原料作为钛水解沉淀的中和剂和捕收剂，通过氧化水解将钛白废酸中的钛沉淀富集到优化钛渣中，同时将钛渣中的钒、钪等稀有金属浸出进入溶液，得到含钒钪等稀有元素的贫钛液，贫钛液经萃取或离子交换回收钒、钪等，优化钛渣用硫酸法生产钛白，钛白生产过程产出的废酸返回循环使用。本方法从源头上解决了硫酸法钛白废酸的排放与环境问题，具有钛白产品质量好、钛回收率高、并且可综合回收钒钪等稀有元素的优点。
