separately mixing mineral powder (03), in particular calcium carbonate (CaCO) using a mechanical mixing device (20)₃) Talc, or mica, and a dispersant (05), in particular SOLPLUS, for a predetermined period of time until a homogeneous mineral mixture (22) is formed;

melting the homogeneous mineral mixture (22) in a melting device (25) to obtain a mineral paste (38);

applying the mineral paste (38) as a coating to both sides of the extruded non-woven PET sheet (33) by a coating device (45) to form mineral paper (46);

the mineral paper (46) is wound using a winder (50) to produce a mineral paper roll (51).
