Gypsum is one of the building materials that is pulled out of the soil and mines, and is in many places found fifth. Gypsum, which is used today in building, is derived from gypsum from the soil and mines. Of course, for the construction of gypsum, a process is underway that is the process of baking and milling the gypsum. We refer to gypsum and we briefly refer to it, but we did not explain how gypsum is extracted, which is the most important process of producing this material. In the following, we will briefly describe the gypsum extraction.
Extraction of natural gypsum in general and in most cases from mines. Gypsum mines are scattered across the globe and in different regions, and Iran is also rich in mines. Of course, in some places gypsum is extracted from the ground. Gypsum is extracted from the surface of the earth through an explosion. This explosion is carried out stepwise and then the extraction operation is carried out. The extracted stones are explosive in size, though these rocks have 0 to 3% of their moisture content. Extruded gypsum is used in both inorganic and superficial methods other than gypsum to create adhesion in cement.
Gypsum, as mentioned above, after extraction, has some internal moisture content. To measure this moisture, first remove some gypsum as a sample and place it at a temperature of 40 to 45 degrees Celsius. The duration of exposure to gypsum is also 8-10 minutes. After the heat is over, gypsum is weighed again. Gypsum will surely fall due to heat loss, which will be calculated as percentages. This percentage will in fact be the same as the moisture content of the plaster Gypsum extraction is done by companies that specialize in this field. One of these companies is KSKISH Co., which has been operating in this field for many years. KSKISH Co exports its extractive materials to any region of the country and has very good prices that compete with other companies' prices
