Separation ilmenite ore
In accordance with the invention, it has now been found that ilmenite from various sources can be purified. ores which provide the ilmenite are those found on the east coast of south africa, e.g., richard39s bay and ste. lucia, and on the east coast of australia, e.g., stradbrooke island. richard39s bay ore which has been concentrated has an assay of 47.5 percent tio2 36.5 percent fe and 0.40 percent cr2 o3. the ilmenite concentrate is then subjected to a magnetic separation in a wet separation process and the high magnetically susceptible chromite contaminant is removed therefrom.
