In the Upper Palatinate region, we have one of the most important German kaolin and quartz deposits and can thus access mineral raw materials that can be used in many different ways. We have been mining mineral raw materials there since 1895. 

Dorfner recognized the potential of these raw materials early on and consistently expanded it. In the meantime, our high-quality industrial minerals and highly refined REFINERALS® Basis are irreplaceable for numerous applications and in many branches of industry. An own standard in terms of quality. 

We offer you:
Innovative functional fillers for a wide range of applications
High-quality mineral raw materials
Technical perfection
Economic efficiency
Efficient system costs
Solid development consulting 

We supply industrial minerals and REFINERALS®. Products which we, as development partners of our customers, manufacture according to customer requirements. For example, our synthetic resin based composite materials for the production of kitchen and sanitary objects in technical and economic perfection. 

We think like our customers think. We are at home in many different target markets and always see things from the customer's perspective. We have our own efficient, application-oriented development department which we are continuously expanding. This is where we bundle our expert knowledge. We not only offer sound, product-specific expertise but also know how to integrate our products smoothly into manufacturing processes.
