Extraction The most advanced equipment carries out the extraction work in our quarries. Slate is not only extracted in the mine, but also in the open pit. In the "La Fraguiña" and "Fontelas" mines the extraction of slate is carried out underground. La Fraguiña is the largest slate mine in the world. Here we began to extract slate as early as 1968. At that time slate was only mined in the open. In the early 1990s, the extraction system began to be carried out only underground, which allows optimal use of the deposit. "Valdemiguel" is one of our quarries located in the "Valdeorras" valley, here we have been mining slate under the open sky since 1970. We also extract slate in the "Fontelas" and "La Ponderosa" quarries. The fully automated extraction makes their work easier for workers, both in the mine and in the open pit, and also ensures that the valuable stone is treated with the utmost care. Serrated In the production hall, the first step in the production process is sawing. Modern split-leather installations work automatically. During sawing, large slate blocks become manageable pieces. Depending on the final format of the piece, the block is cut, always maintaining maximum use. Carved In Germany the thickness of the roofing slate is 4-6 mm, in France 3 mm. The farmer when exfoliating the stone in sheets has to take into account the thickness depending on the country of destination. After sawing the blocks are distributed to different tilling stations. The carving is done manually with hammer and nickel. Finish The finishing of our slate pieces is automatic, adapting it to the type of cover desired. This automated finishing guarantees the homogeneity of the pieces, so we can speak of uniform "templates". Quality Although the quality of the slates is constantly controlled in each step of the manufacturing process, each of the pieces undergoes a final quality control once the production is finished. Logistics Slate is supplied from the central warehouse of the Spanish company CAFERSA to Germany, France, Great Britain, Ireland, Belgium and other important markets. produced with ecomas ® Content Management System
