SPECTACULAR FLUORITE FROM THE BERTA MINE IN PAPIOL (BARCELONA) MIXED WITH CALCITE CRYSTALS. PIECE WITH DOBE OR TWIN CRYSTALLIZATION OF THE MAIN CRYSTAL AND LARGE SIZE. IN THE CENTRAL PART WE CAN OBSERVE COMPLETE CALCITE CRYSTALS. CURRENTLY THE MINE IS CLOSED, IT IS VERY COMPLICATED TO OBTAIN OR OBTAIN THIS SPECIFIC MINERAL.
Fluorite is a group III mineral (halides) that, according to Strunz's classification, formed the elements calcium and fluorine.
Its structure belongs to the cubic system, and it has a cubic, octahedral and dodecahedral rhomboid habit.
Fluorite exhibits thermoluminescence and fluorescence physical properties.
In industry, it is mainly used in the metallurgy of iron and steel. It is used as a source of fluorine and hydrofluoric acid, also in the glazing of ceramics and in the manufacture of optical glasses.
The beauty of the specimens makes it a highly appreciated mineral by museums and private collectors.
