Our self-perception

We, HOFFMANN MINERAL, perceive ourselves to be an innovative filler materials specialist who produces, refines and markets products based on Neuburg Siliceous Earth. Our expertise and production equipment for refining and marketing are also specifically used for other materials.

We offer a balanced, competitive assortment of products based on Neuburg Siliceous Earth. Our objective is to achieve the most complete, high-quality utilization of the available deposit.

quality - in the sense of TQM,

Contract production - particularly post-processing - of industrial raw materials round out the core array of silica products in a prudent manner and this is being expanded to a second mainstay. Silica products always have priority.

The extraction sites are restored again to their legitimate nature and incorporated into the landscape. Furthermore we encourage the protection of species.
