Representativeness of a Linear Surface Model for Coal Samples

Representativeness of a Linear Surface Model for Coal Samples

The Región Carbonífera has bituminous and sub-bituminous coal with variable properties in its sub-basins. A factorial design of 22 is proposed to develop a two-stage flotation series (robust and fine), determining a reaction model that tests the uniformity trend within each sub-basin. Two samples we...

A factorial design of 22 is proposed to develop a two-stage flotation series (robust and fine), determining a reaction model that tests the uniformity trend within each sub-basin. Two samples were taken from the Saltillito-Lampacitos sub-basin, prepared to -#100, characterized and concentrated by flotation. Grade (%) was proposed as a control variable and as study variables the concentration of frother (MIBC, [A]) and the amount of collector (diesel, [B]) were modeled in Minitab17 and Statistica 13.3 programs, the surface reaction model obtained was Grade=92.396-0.007033[A]-0.014194[B]. The difference between the reaction model and the experimental data is acceptable, so it is concluded that there is a predictive behavior and there is uniformity within the sub-basin. La Región Carbonífera posee carbón bituminoso y sub-bituminoso con propiedades variables en sus subcuencas. Se propone un diseño factorial de 22 para desarrollar una serie de flotaciones en dos etapas (robusta y fina), determinando un modelo de reacción que prueba la tendencia de uniformidad existente dentro de cada subcuenca. Se tomaron dos muestras de la subcuenca Saltillito-Lampacitos, se prepararon a -#100, se caracterizaron y concentraron por flotación. Se propone como variable de control el Grado (%) y como variables de estudio la concentración de espumante (MIBC, [A]) y la cantidad de colector (diésel, [B]) se modeló en los programas Minitab17 y Statistica 13.3, el modelo de reacción de superficie obtenido fue Grado=92.396-0.007033[A]-0.014194[B]. La diferencia entre el modelo de reacción y los datos experimentales es aceptable por lo que se concluye que existe un comportamiento predictivo y hay una uniformidad dentro de la subcuenca.
