Abstract

SE REFIERE A UN METODO PARA SEPARAR SOLIDOS DE MENA SUSPENDIDOS EN UN LIQUIDO DURANTE EL PROCESO DE FLOTACION DE ESPUMA, A LOS QUE SE DENOMINA COLAS, TALES COMO: SOLIDOS SUSPENDIDOS OBTENIDOS A PARTIR DE: UNA MENA DE MINERAL DE PLATINO, MENA DE COBRE, MASA DE MINERAL DE MENA DE DIAMANTE, MASA DE CARBON, MINERAL DE ARENA DE ALQUITRAN; QUE PRESENTAN AL MENOS DOS MINERALES DISTINTOS DE OXIDO DE HIERRO U OXIDO DE ESTANO COMO CUARZO Y ARCILLAS, COMPRENDIENDO: PONER EN CONTACTO DICHOS SOLIDOS CON UN POLIMERO FORMADO POR LA REACCION DE UNA AMIDA TAL COMO ACRILAMIDA Y SIMILARES CON UNA HIDROXILAMINA; DONDE EL POLIMERO FLOCULA A LOS SOLIDOS AUMENTANDO LA VELOCIDAD DE SEDIMENTACION Y DISMINUYENDO LA TURBIEDAD DEL LIQUIDO
