Lead recovery by flotation with sodium lauryl sulfate

Abstract: ResumoO processo metalúrgico para reciclagem de chumbo, a partir de baterias automotivas usadas, gera uma escória constituída, basicamente, por ferro e chumbo. A recuperação do chumbo contido nesse material descartado é de grande interesse econômico e ambiental. O trabalho teve, como objetivo, estudar a possibilidade de recuperar o chumbo através de flotação com sulfato lauril de sódio (SLS). A fim de se verificarem as condições mais favoráveis para a seletividade, procurou-se identificar o mecanismo de adsorç… Show more

“…It may be suggested that sodium lauryl sulfate attaches to kasolite mineral through lead and brings it to the froth. This is in agreement with Alessandra Gorette de Morais, et.al (2013) who found that the great recovery of lead was obtained by flotation at pH 10 with only (1×10 -3 ) M sodium lauryl sulfate and poor selectivity was observed under alkaline conditions resulting in low grade concentrate [20]. Relation between pH and recovery of uranium % using cupferron concentration (1×10 -3 ) M, on the ground ore (less than 62 µm) for 120 sec.…”
