Ilmenite - an overview ScienceDirect Topics

Ilmenite (Fe-TiO 2) Ilmenite has a specific gravity of up to 5.1. Saasen et al. (2001) reported a higher drilling penetration rate from the use of ilmenite, because a lesser colloidal solids fraction was produced during drilling. 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 ...

An overview of the Namakwa Sands Ilmenite Smelting Operations

Ilmenite is smelted to produce two grades of saleable titania slag, and several grades of pig iron, and is also shipped via the Saldanha harbour to overseas markets. The project was initiated in two phases, at a total cost of R2.1 billion. At full capacity, 18 million metric tons per annum of ore is mined to produce 200 000 tons of titania slag, 120 000 tons of high-purity pig iron, 25 000 ...

Electrostatic Separation - an overview ScienceDirect Topics

As a combined processing technology, rare earth drum magnets are first used to remove ilmenite from mined heavy mineral concentrate feed, from which most of the ilmenite can be recovered. Then non-magnetic minerals are processed by electrostatic separation to obtain conductor minerals (rutile and leucoxene) and non-conductors (consisting of zircon, kyanite, quartz, monazite and staurolite).
