As a result, we found that talc (platy or round, Fe-rich) prevails (65–90%) over Cr-chlorite (7–26%), halloysite, chromite, rutile, brucite and magnesite. Chemically, talc ores are made up of SiO 2, MgO, Fe 2 O 3 and minor Al 2 O 3. Mode values range from 50 to 55 μm at Memel and from 30 to 90 μm at Pout-Kelle.
