Froth floatation 1. Froth Floatation Presented By: Gulfam Hussain 2. Introduction Floatation is an extractive process where various minerals can be selectively extracted. Flotation is a selective process and can be used to achieve specific separations from complex ores. For example, in poly-metal ores such as Pb-Zn- Cu, floatation allows separate extraction of Pb, Cu and Zn.

the most popular flotation route in iron ore industry, the direct flotation of iron ox ides still appears desirable for some low grade iron ores that contain a vast amount of quartz. For example, at Republic Mine, Michigan, U.S.A., a hematite ore is upgraded from 36.5% Fe to 65.4% Fe with a Fe recovery of 82.5% using the direct flotation route.

INTRODUCTION Research on the flotation of iron ore, on either a bench or a pilot-plant scale, started towards 1931 (Crabtree and Vincent, 1962). It was mostly confined to ores containing siliceous gangue, which appears to be the most abundant type in the world and the reserves of which, when based on a minimum tenor of 30 to 35% iron, amounts

Froth Flotation. One of the biggest losses is the increasing amount of Silica (SiO2) in the concentrate coming out of their flotation plants. Excursions in contracts and downgrades of Fe content took place over the last 12 months accounting for over $ 220M. A large concern is a delay between lab samples to measure impurity levels in the output

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.
