Using the data obtained from the small pilot-scale testing program, a larger scale pilot plant was commissioned and operated to compile additional data on the performance of the larger scale
This material has been classified during many cycles in the pilot plant, so that the probability of agglomeration and blockages is low. Another advantage is that highly cycled ilmenite is known to be more reactive than fresh material (Abad et al., 2011). The average diameter of the particles is d p(av,ilmenite) = 154 μm. Furthermore, an iron ...

The company started an ilmenite pilot plant in October 2019. Based on the promising results, the board approved construction of a full-scale plant. The advanced engineering and construction of the ilmenite concentration plant is expected to cost approximately $25.2 million with the majority of these costs being incurred in 2022.
About Ilmenite & Titanium. Ilmenite is a common accessory mineral in igneous rocks, sediments, and sedimentary rocks in many parts of the world. It is an oxide mineral of iron and titanium, also known as titanium magnetite, and its composition is FeTiO3. Ilmenite is a heavy (specific gravity 4.7), moderately hard (Mohs hardness 5.6 to 6), opaque black mineral with a submetallic luster.
The optimum conditions for leaching ilmenite in this study were found to be 5–7.5 M HCl solution with a total Cl− concentration of ~ 500 g/L, 3.3% (w/w) pulp density, 70–80 °C and 4–6 h ...
ilmenite-smelting campaigns on the 3 MVA pilot furnace at Kumba Resources' Research and Development facilities. These campaigns varied in length from one week to six weeks, with the majority being of the order of two weeks. The objectives of these campaigns included the following: • Testing of different feedstocks for ilmenite smelting.

In pilot testing conducted to obtain data for a cost estimation, a synthesized product containing about 88 wt-pct TiO2 and less than 2 pct FeO was extracted from a rock-type ilmenite concentrate containing about 45 wt-pct TiO2. The estimated fixed capital cost (on a mid-1975 basis) of a plant producing 500 tpd of synthetic rutile is $28,290,100.

This review collects relevant information about the status of CLC technology. A table related to the operational experience with ilmenite in CLC (1524 h) including pilot plants locations and fuels may be found herein. Likewise, the experience of 12000 h of oxygen carrier aided combustion (OCAC) mode with ilmenite is described.
Electric arc furnace smelting is one of the main processing routes used to upgrade ilmenite into a suitable titanium feedstock for pigment and sponge producers. During the ilmenite smelting process the iron oxides present in the ilmenite concentrate matrix are reduced to metallic form by using carbon as the reductant. A slag rich in TiO2 and low in FeO content remains, together …
