MiniFlex is used in many fields of industry and research, for substances ranging from inorganic materials such as ceramics and minerals, to pharmaceuticals and other organic materials. It was found that the main component dolomite (CaMg(CO₃)₂) contains trace amounts of calcite (CaCO₃) and barite (BaSO₄).
