摘要： The presence of chromite in significant amount in ilmenite downgrades the market value of the ilmenite. A substantial amount of the chromite may be removed, firstly by a reduction step, secondly by a leaching, aeration or oxidation roasting step and finally by a physical separation step. An optional preoxidation may precede the reduction step and an optional physical separation step may be inserted between the first and second steps. The first step is one of solid state reduction above 1000 DEG C in the range 1000-1300 DEG C with coke, coal, gaseous fuels, such as natural/petroleum gas or liquid fuels, such as oils or their products. Various additives such as alkali metal salts, chlorides, magnesium or manganese compounds may be added to promote segregation of the reduced metallics, (Fe, Cr). The reduction may be carried out in fluidised bed or rotary kiln furnaces. The second step consists preferably of oxidising or aerated dilute acid/ferrous-ferric salt attack, aqueous aeration in the presence of an activator or thermal oxidation roasting. The aqueous aeration, which has been used in this specification consists of bubbling air for 5 to 16 hours, depending on the finished requirement, with strong agitation in the presence of low concentrations (e.g., 0.5 - 1.0 %) of ammonium chloride. Activating agents are selected from sodium or iron chlorides, organic acids and salts. The final physical separation step is usually a magnetic separation, which effectively removes the chromium from the titanium. A magnetic separation may also be inserted after the solid state reduction step, prior to the aeration step. The procedure results in a better than 80 % recovery of the TiO2 content and the removal of about two thirds of the Cr2O3 content.
摘要翻译：钛铁矿中存在大量的铬铁矿降低了钛铁矿的市场价值。可以首先通过还原步骤除去大量的铬铁矿，其次是浸出，曝气或氧化焙烧步骤，最后通过物理分离步骤。可选的预氧化可以在还原步骤之前，并且可以在第一和第二步骤之间插入可选的物理分离步骤。第一步是在1000-1300℃范围内，在焦油，煤，气体燃料如天然气/石油气或液体燃料（如油或其产品）中固相还原1000℃以上。可以加入各种添加剂如碱金属盐，氯化物，镁或锰化合物以促进还原的金属（Fe，Cr）的分离。还原可以在流化床或回转窑炉中进行。第二步最好包括在活化剂或热氧化焙烧的存在下进行氧化或曝气的稀酸/亚铁 - 铁盐攻击，含水曝气。在本说明书中使用的含水曝气由取决于成品要求的鼓泡空气5至16小时，在低浓度（例如0.5-1.0％）氯化铵存在下强烈搅拌。活性剂选自氯化钠或氯化铁，有机酸和盐。最终的物理分离步骤通常是磁分离，其有效地从钛中除去铬。在曝气步骤之前，也可以在固态还原步骤之后插入磁性分离。该过程导致TiO 2含量的回收率优于80％，并且除去约三分之二的Cr 2 O 3含量。

摘要： The specification describes a process for producing synthetic rutile from a titaniferous ore or concentrate. The process involves three basic steps which are reduction, removal or iron by leaching or aeration and removal of other impurities by leaching in a solution of a strong mineral acid such as hydrochloric acid or sulphuric acid. The conditions of reduction are controlled to promote the formation of metallic iron, a major rutile phase and a minor impurity bearing phase. The minor impurity phase may be a metatitanate, an anosovite or a pseudobrookite. However, formation of a metatinatate is normally preferred. Suitable reductants include carbonaceous materials or hydrogen bearing gases such as natural gas or synthesis gas. The process is capable of removing more than 80 % of each of the contained iron magnesium and manganese remaining as oxides after reduction. Substantial proportions of contained aluminium can also be removed.
