The Micronized Group prides itself in being a miner and processor of the highest quality industrial minerals in South Africa. These are used in a diverse range of industries including paints & coatings, glass, ceramics, flooring and personal care products.
Micronized mines and processes 6 industrial minerals and their derivatives, namely: Feldspar, Silica, Mica, Talc, Kaolin & Barytes.
Microbrite® – Milled Feldspar
Our Microbrite® range, known technically as alkali aluminium silicates, are a range of milled feldspar minerals processed from pegmatite deposits at our mine in Limpopo, South Africa.

Screened Feldspar
Offering screened feldspar, providing good dry brightness, from 0.3mm to 25mm utilising the same source of high quality raw feldspar as used in our Microbrite® range.

Microsil® – Milled Silica
Our Microsil® range of milled silica quartz minerals are processed from our pegmatite deposits that are used in our Microbrite® range.
View Milled Silica

Our Microtalc® range are high quality magnesium silicate minerals with a monoclinic crystal structure. When milled into a fine powder, the lamellar (or platey) property gives a smooth soapy feel.

Our Mica range of products occurs as a co-product from the same pegmatite ore body we mine to obtain the Microbrite® range of Feldspars and the Microsil® range of Silica’s.
View Mica
Our Kaolin range of products are mined from our own deposit that forms part of the well-known Grahamstown Kaolinite complex in the Eastern Cape province of South Africa.

Ball Clay
Our Ball Clay (or plastic clays) offer plasticity and wet-strength, good wet and dry brightness, acid resistance, heat stability and used in a wide range of applications.

Also known as also as Barite or Barium Sulphate. With a high specific gravity of 4.5, Barytes is distinctive in non-metallic industrial minerals.

Supersilk derives its name from the soft and silky properties inherent in lamellar structured aluminium silicate ore bodies. Used in coatings, polishes and specialised mastics.
