... Such t itaniferous ores are highly variable in ilmenite and iron oxide content; in the size and physical interlocking of ilmenite and iron oxide mineral part icles; and in associated oxides, sulf ides, and silicates that include vanadium, chromium, nickel, aluminum, calcium, magnesium, zirconium, and other elements. Ilmenite and associated leucoxene also occur in beach and alluvial sands that are the erosional remnants of formerly massive or disseminated hard rock deposits.

... .6 percent ilmenite sand f ram the Lo s Angeles area, using spirals and low intensity and high intensity magnetic equipment, yielded a TiO2 concentrate that analyzed 43 percent TiO2 and 48 percent Fe2O3. Further test work might show that processing the ilmenite-bearing sands to produce a crude heavy minerals product at individual operations followed by centralized processing to recovery magnetite, ilmenite, gold, platinum, and even thorium-uranium may be worthwhile ~ Come s 1980)
