Heavy mineral sands are natural sedimentary deposits containing economic quantities of rutile, ilmenite, zircon, monazite, and xenotime. These heavy minerals are sources for pigments, high-grade titanium …

The mineral phase constituents of the ilmenite beach placer sands were studied before pre-oxidation and additive leaching in a chloride environment. During observations using XRD and HR-SEM, the ilmenite beach placer sands exhibited signature rhombohedral crystal form and crescentic pits with evidence of alteration phases.

Ilmenite was used in drilling operations in the North Sea in 1979 and 1980. The ilmenite was a fairly coarse ground material compared to the presently used ilmenite. The drilling fluid properties were easier to control compared to drilling with barite. Again, this was because ilmenite has a lower tendency of being ground down to finer particles.

The CP ilmenite varies from pure ilmenite to highly impure variety having intergrowths and inclusions of other oxide and silicate minerals. Ilmenite occurs as …
