However, the distribution of ilmenite is neither high nor uniform throughout the lunar surface and therefore, needs beneficiation, which is an important intermediate step for ilmenite-based oxygen production. A regolith beneficiation testbed was developed at DLR Bremen which is a TRL 4 level representation of the technology.

Therefore, mainly monazite and ilmenite were considered as target minerals for the beneficiation process, whereas quartz was considered as a main gangue mineral from the feed sample. Table 2 shows the mass fraction (%) and concentration (%) of the main elements as a function of particle size in the feed sample.

However, a small portion of ilmenite particles acquired from different mine lots and beneficiation processes are very fine, which would fall into the overflow particle size. Furthermore, the particle size of the samples would slightly decrease due to the friction between the particles and the crush of the stirring paddle.

It occurs with other associated industrial placer heavy minerals such as ilmenite, garnet, rutile, zircon, and sillimanite at very low concentrations and is recovered as a by-product. The beneficiation processes for the recovery of total heavy minerals are specific, and dedicated flow sheets are adopted due to variations in mineral compositions.
