Abstract

Un método para aumentar el rendimiento de hulla oxidada sometida a un tratamiento de concentración por flotación por espuma, que consiste en utilizar como promotor de la flotación una emulsión invertible de agua en aceite de poliacrilato sódico, a una dosis calculada entre 0,017 y 0,5 libras de poliacrilato sódico seco por ton de hulla seca (0,0085-0,25 kg/Tm).
