1. Introduction. Synthetic rutile (SR) is a chemically modified ilmenite, which has most of the non titanium components removed. SR is used as feed stock for the production of titanium dioxide pigment via chlorination-oxidation process, and titanium metal via magnesiothermic reduction process, or directly used as welding electrode covering …

Natural concentrations of industrially valuable minerals are far less likely to be found on the Moon than on the Earth. But that is all the more reason for devising beneficiation processes to concentrate and extract the useful mineral components in lunar rocks and soils. As an example of a useful mineral that can be beneficiated, it has been estimated that …

In addition to Ti-slag, ilmenite is sometimes beneficiated into SR, usually this process is undertaken on HMS derived ilmenite rather than hard-rock ilmenite. SR is produced predominantly by Tronox and Iluka Resources in Western Australia with a smaller volume from India. Only sustainability data from Iluka is available, however since Iluka ...

Titanium, the ninth most abundant element, occurs mainly in minable form as ilmenite (95%) and rutile (5%) minerals. The current world consumption of these minerals is used mainly to produce titanium dioxide pigments, with the balance in welding rod flux and titanium metal. Ilmenite is currently being mined in annual quantities eight times larger …

As a comparative reference study, the ilmenite was firstly oxidized in air at the temperature range of 650 °C–750 °C and the results are given in Fig. 3 a. It was seen that the oxidation rate of ilmenite was slow since the Fe 2+ conversion was only 21% after roasting for 60 min at 650 °C. Temperature rise favored the oxidation rate and 75% of …

The process is comprised of metallisation of ilmenite followed by aeration rusting for the production of beneficiated ilmenite and the reoxdiation of beneficiated ilmenite followed by acid leaching. Reoxidation of beneficiated ilmenite plays a major role in rendering the product amenable to acid attack and removal of residual iron. This paper ...
