Abstract
Procedimiento mejorado de separación del carbón y los estériles en una extracción carbonífera. El procedimiento consisteesencialmente en hacer una separación densimétrica del todo-uno extraído en la mina, de forma, en que una balsa de flotación, que contiene un medio denso de densidad controlada (entre 1,35-1,60 g/cm{sup,3 ), se vierte el material a tratarproduciéndose la flotación del carbón, con una densidad media de 1,25 g/cm{sup,3 , y la sedimentación de los estériles, con una densidad media de 2,5 g/cm{sup,3 . La porción de carbón flotada se recoge en la superficie de la balsa con un medio mecánico, se lava con agua y se escurre, obteniéndoseel carbón vendible. La porción sedimentada (los estériles) se extraen mecánicamente de forma continua, llevándose a lasescombreras.El producto utilizado para la formación del medio denso en la balsa de flotación es una marga arcillosa obtenido junto con el carbón en el material extraído en la mina.El procedimiento se usa para tratar los materialesextraídosen cuencas carboníferas del bajo segre.Improved procedure for separating coal and waste in a coal extraction. The procedure consists essentially in making a densimetric separation of the all-one extracted in the mine, in such a way that a float raft, which contains a dense medium of controlled density (between 1.35-1.60 g / cm {sup, 3), the material to be treated is poured producing the carbon flotation, with an average density of 1.25 g / cm {sup, 3, and the sedimentation of the sterile, with an average density of 2.5 g / cm {sup ,3 . The floating coal portion is collected on the surface of the raft with a mechanical means, washed with water and drained, obtaining the salable coal. The settled portion (the sterile ones) are continuously extracted mechanically, taking them to the dumps. The product used for the formation of the dense medium in the flotation basin is a clay loam obtained together with the coal in the material extracted in the mine. This procedure is used to treat the materials extracted in coal basins of the lower segre.
