Samples of raw ore, intermediate stages and finished product from different batches were collected from ilmenite processing industries. The process of purification of the ore in these processing plants involves the following procedure. The conducting and non-conducting fraction of the raw ore (Stage-1) is separated using a magnetic separator.

Natural rutile was the feedstock of choice at the early years of the Kroll process, but nowadays it comes in limited supply. Titanium dioxide slags are produced by reduction smelting of ilmenite in electric arc furnaces. The slag grade (sulfate or chloride) depends essentially on the quality of the ore or concentrate fed to the slag furnaces.
