Magnor Minerals AS

Magnor Minerals produces various types of magnesium oxide that are useful in hydrometallurgy, environmental protection, fertilizers, pulp and paper, and animal feed.

The company's main product is CCM and the product quality is exceptionally high and stable as the company's CCM is made with magnesium from dolomite and seawater.

Magnor Minerals' main raw material is Norwegian dolomite, from Hammerfall in northern Norway, which is crushed and then calcined at 1100 degrees in a calciner.

In the next process step, dolime is mixed with seawater and magnesium hydroxide is formed. This proceeds to filtration where water is removed and the product is calcined at moderate temperatures in a rotary kiln. The result is magnesium oxide, MgO.

Maximum capacity is 70,000 tonnes of MgO per year.

The company's by-products include dolomite dust, half-burnt dolomite, filter cake, sand, magnokalk and ESP dust. The by-products are used for, among other things, soil improvement.
