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 SiO2, MgO, Fe2O3 and minor Al2O3. Mode values range from 50 to 55 μm at Memel and from 30 to 90 μm at Pout-Kelle.

The talc used in the examples was a commercial platy talc product. The talc was produced by wet processing an ore from a Vermont deposit. The wet processing included beneficiation by flotation an aqueous medium, drying and fine milling. The product was essentially finer than 325 mesh and had an average particle size of 2.7 microns.

The platy shape of talc particles improves the suspension of solids in the can and helps the liquid paint adhere to a wall without sagging. Powdered talc is a very bright white color. This makes talc an excellent filler in paint because it simultaneously serves to whiten and brighten the paint. Talc's low hardness is valued because it causes ...

After the crude rock is crushed, it is often subjected to a manual selection process, although automated techniques are now being introduced. ... One of the advantages of platy fillers like talc is a significant reduction in ...
The mineral talc is a hydrous magnesium silicate. A massive talcose rock is called steatite, and an impure massive variety is known as soapstone. Talc is used commercially because of its fragrance retention, luster, purity, softness, and whiteness. Other commercially important properties of talc are its chemical inertness, high dielectric strength, high …
