US9004286B2 - Process for concentrating manganese ores

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 ...

Effect of Mn (II) on quartz flotation using dodecylamine

2014-8-29  Abstract: Quartz is, in most cases, the major gangue mineral found in the manganese ore. Mn iron, dissolved from the surface of ore, will determine the interfacial properties of the particles and, thus, their flotation behavior. In this work, the effect of Mn2+

Comparative studies of reverse cationic/anionic flotation ...

2011-9-14  1. Introduction. Reverse cationic flotation is currently the most widely used flotation route in the iron ore industry. The metal loss at the de-sliming stage, which is essential in reverse cationic flotation, and the high cost of amine collectors are the common issues/problems of reverse cationic flotation.
