Abstract

Utilización de aceites vegetales como reactivos de flotación de carbones y estériles. La invención hace relación a la utilización de los aceites de origen vegetal, crudos y refinados, aptos o no para el consumo humano, como reactivos de flotación en la industria del carbón. La flotación es un proceso industrial que se utiliza para la depuración de la fracción de finos (<1mm) de carbón, antes de su combustión en las centrales termoeléctricas, y también para la recuperación del carbón de los estériles finos acumulados en las escombreras o balsas.Use of vegetable oils as coal and waste flotation reagents. The invention relates to the use of oils of vegetable origin, crude and refined, suitable or not for human consumption, as flotation reagents in the coal industry. Flotation is an industrial process that is used to purify the fine fraction (<1mm) of coal, before its combustion in thermoelectric power plants, and also for the recovery of coal from the fine waste accumulated in tailings or ponds. .
