Abstract

1. Un procedimiento para calcinar con tostación, materiales de sulfuro de zinc/plomo, caracterizado porque, en una primera etapa se forman pellas sustancialmente esféricas constituídas, predominantemente, por sulfuro de plomo, que se revisten con material predominantemente de sulfuro de zinc, y luego en una segunda etapa se calcinan con tostación las citadas pellas revestidas, en un aparato tostador para efectuar la oxidación del sulfuro, predominantemente a óxido.
