Title (EN) DEWATERING FINE COAL SLURRIES USING ORGANOPOLYSILOXANES
(FR) ASSECHAGE DE BOUES DE CHARBON FIN PAR L'UTILISATION D'ORGANOPOLYSILOXANES
Abstract: front page image
(EN)Aqueous slurries of fine coal are dewatered by a process which comprises mixing an organopolysiloxane with the slurry, separating the slurry to recover the fine coal and further drying the fine coal, if desired. The use of water-soluble organopolysiloxanes or water-emulsifiable organopolysiloxanes provides improved separating and/or improved drying of fine coal in the dewatering process that is disclosed.
(FR)Les boues aqueuses de charbon fin sont assechees par un procede consistant a melanger a la boue un organopolysiloxane, a separer la boue pour recuperer le charbon fin et a secher facultativement le charbon fin. L'utilisation d'organopolysiloxanes solubles a l'eau ou d'organopolysiloxanes emulsifiables a l'eau permet une separation et/ou un sechage ameliores du charbon fin lors du procede d'assechage ci-decrit.
