Abstract

See full text

A process for concentrating manganese from the tailing of a manganese-carrying mineral including removing a coarse particle size fraction from the tailing, desliming and conducting an acidic or a basic reverse cationic flotation. The manganese-carrying minerals are typically minerals with low manganese content from the lithologies “Tabular Pelite” (or PETB), Pelite Siltite (or PEST), Detritic (or DETR), Rich Pelite (or PERC) and Metallurgical Bioxide (or BXME). In another aspect, the present invention also relates to a reverse cationic flotation used to concentrate manganese which is carried out using depressor agents and collector agents as flotation reagents.
