摘要： The specification discloses a method of making acid digestible titania. The method comprises the steps of: (1) adding a magnesium or manganese compound to a titaniferous mineral if the content of manganese and magnesium in the mineral is insufficient; (2) heating the mineral in the presence of a reductant for a sufficient length of time and at a sufficiently high temperature to permit the reduction of iron containing compounds to metallic iron and enable titania present to convert to an acid digestible form; (3) cooling the mineral; and (4) separating iron from the mineral by means of an aqueous aeration step. The titaniferous mineral contains insufficient magnesium and manganese if the following expression is not satisfied: 1.98a + 1.14b/d >/= 0.08 where a represents the percentage by weight of MgO contained in the mineral, (b) represents the percentage by weight fo MnO contained in the mineral; and (d) represents the percentage by weight of TiO2 contained in the mineral. The magnesium or manganese compound is either an oxide or a compound that is capable of converting to an oxide under reaction conditions. An aqueous aeration technique described in the specification involves the use of a sequesterant that is capable of sequestering iron from the mineral without significantly lowering the local pH while at the same time permitting the formation of an oxide of iron at a point away from the mineral. An example of such a sequesterant is citric acid.
摘要翻译：该说明书公开了一种制备酸可消化的二氧化钛的方法。该方法包括以下步骤：（1）如果矿物中锰和镁的含量不足，则将镁或锰化合物加入含钛矿物中; （2）在还原剂存在下将矿物加热足够长的时间和足够高的温度以允许将含铁化合物还原成金属铁，并使二氧化钛存在以转化成酸可消化形式; （3）冷却矿物; 和（4）通过含水曝气步骤从矿物中分离铁。如果不满足以下表达式，则含钛矿物含有不足的镁和锰：1.98a + 1.14b / d> / = 0.08其中a表示矿物中所含的MgO的重量百分数，（b）矿物中含有MnO; 和（d）表示矿物中所含的TiO 2的重量百分比。镁或锰化合物是在反应条件下能够转化为氧化物的氧化物或化合物。说明书中描述的含水曝气技术涉及使用能够从矿物中螯合铁的螯合剂，而不显着降低局部pH，同时允许在远离矿物质的点形成铁氧化物。这种螯合剂的实例是柠檬酸。

摘要： The present invention relates to a zero-waste process for extraction of alumina from différent types of bauxite ores and red mud residues and of titanium dioxide from ilmenite. Iron oxide is first reduced to metallic iron above the melting point of C-saturated cast iron alloy which yields a high-C iron alloy and an AI and Ti metal oxide rich slag which is then treated with alkali carbonate to form alkali aluminates and titanates. The alkali aluminates are separated by water leaching from which the hydroxide of alumina is precipitated by bubbling C0 2 . The residue from water leaching is treated with sulphuric acid and Ti0 2 is precipitated via a hydrolysis route. The process recovers most of the metal values and generates only small quantities of silicious residues at pH 4-5 which can be used for soil conditioning. The present also relates to a method for selective separation of Ti0 2 -rich oxides from titaniferrous ore/residue materials via oxidative roasting in the presence of alkali carbonate or carbonates followed by aqueous leaching of the roasted material and selective precipitation of Ti0 2 under controlled condition below pH=4.

摘要： The invention provides a method for the production of a metal, the method comprising the steps of mixing an oxide of the metal with a reducing agent comprising a Group II metal or a hydride thereof in the presence of water and/or an organic solvent, heating the mixture of oxide and reducing agent, leaching the resulting material with water; and washing the leached material with a dilute aqueous acid. Typically, the metal is a transition or rare earth metal, the oxide of the metal is an oxide of a transition or rare earth metal, and the reducing agent is selected from calcium or magnesium or the hydrides of calcium and magnesium. The metal is generally obtained at a purity of around 98.5-99.1 %, and the method is much quicker than the methods of the prior art and has a much lower carbon footprint, thereby providing an option which is more sustainable, environmentally friendly, and accommodative for industries. Particularly good results are observed in the production of transition metals such as titanium, tantalum and niobium.

摘要： A titanium dioxide compound was isolated from a rare type of naturally occurring ore. Processes for efficiently isolating and obtaining these TiO2 compounds, as well as methods for using them have been developed. These TiO2 compounds may be used directly in applications such as paper, plastics and paints without being subjected to the chloride or sulfate processes. Also they made be used as a feedstock for the chloride or sulfate processes. In order to obtain these TiO2 compounds, one may grind or pulverize the naturally occurring ore, disperse it in a solution or suspension, and process it by selective flocculation or aqueous biphasic extraction.
