Natural gypsum is mined. Gypsum mining is easy, as plaster kits are usually located near the surface, so they can be excavated by openwork. Mineral plaster Gypsum mine is located in many countries of the world, but Hungary is poor in natural gypsum. Among the surrounding countries, gypsum mines are located in Romania, Austria and Poland. Products marketed by Albagips contain only natural mineral plaster, providing the best physiological effects, the purest and most natural building material. Rea plaster In contrast to mineral gypsum, REAgipse is obtained by the process of desulphurisation of smoke emitted by power plants. In high mass and supposedly chemically pure, REAgipse is produced by reducing the sulfur dioxide content of flue gases by using wet limestone technology, which is industrially so-called. using desulphurisation equipment. In Hungary, desulphurisation has been operating since 2008 in the Visontai thermal power plant of Mátrai Erőmű Zrt. (The incomplete but more detailed and understandable description of the technology is available on the website of Mátra Power Plant.) The gypsum thus obtained is used as a raw material for the production of building boards of a Hungarian plasterboard manufacturing company.
