The industrial process is described in the simplified flow chart in Fig. 1. The final phase of the dry separation process produces zirconite (zirconium silicate), ilmenite (iron titanate) and rutile (titanium dioxide) that are sold directly from the mill,. Nowadays, monazite is stored for a new process in the future, which is now being developed.

Zircon Mining Mining of mineral sands can be by both dry mining and wet (dredge) mining methods. In some countries, mineral sands products, principally titanium minerals, are also recovered from hard rock mining methods. Dry mining is suitable where deposits are shallow, contain hard bands of rock, or are in a series of unconnected ore bodies.

Custom milling became increasingly important in the 1960s. Zirconium silicate, ceramic frits and enamel was milled. It was because of this procedure that Helmut Kreutz came in contact with Degussa. Subsequently, a development partnership was established during which a continuous, non-ferrous dry milling process was developed.
