Abstract
METODO DE SEPRACION DE ARCILLA Y PIRITA DE LA HULLA.COMPRENDE LA REACCION DE UNA SUSPENSION DE PARTICULAS DE HULLA PROCEDENTE DE UNA CORRIENTE DE ALIMENTACION DE HULLA CONTAMINADA CON ARCILLA Y PIRITA; AJUSTE DEL PH DE LA SUSPENSION AL VALOR ADECUADO PARA MANTENER UNA DISPERSION COLOIDAL EN LA QUE LAS PARTICULAS DE ARCILLA Y PIRITA SON COLOIDALES. AGITACION DE LA SUSPENSION DE PARTICULAS DE HULLA PARA DESPRENDER DE ESTA LAS PARTICULAS DE ARCILLA Y PIRITA Y FORMAR UNA SUSPENSION COLOIDAL CON LAS MISMAS; RECUPERACION DE LA SUSPENSION DE PARTICULAS DE HULLA CON TAMAN/O SUPERIOR A 2BMB. AJUSTAR EL PH DE ESTA SUSPENSION; FORMAR DE NUEVO UNA DISPERSION COLOIDAL DE PARTICULAS DE ARCILLA Y PIRITA DESPRENDIDAS DE LA HULLA; Y RECUPERAR LAS PARTICULAS DE HULLA DE TAMAN/O SUPERIOR A 2BMB.
