RG Mineral AS

is part of RG Mineral AS. The business started in 1990 after investment in the world’s first production plant for sub micron iron oxides processed from natural magnetite. In 1995 the production plant was enlarged to 10 000 tonnes per annum capacity.

COLORANA^® products are based on natural magnetite from different sources. The magnetite raw material is upgraded to almost pure magnetite by state-of-the-art ore dressing methods before it enters the COLORANA^® plant.

The COLORANA^® process is a continuous operation involving wet ultrafine milling, dewatering and drying.

The COLORANA^® red product line is processed from COLORANA^® black by thermal decomposition of magnetite.

Micronised red and black COLORANA^® pigments form the COLORANA^® D-range. The deagglomeration (micronisation) process involves a unique disintegration technology combined with highly efficient, superfine air-classifiers, altogheter the ultimate solution to create micronised iron oxide pigments of:
