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.

Yes, gravity separation is the way to go in case of chromite. If there are other valuable species, e.g. PGM-containing minerals, they can be floated first and then tails go to gravity separation. Actually chromite flotation should be similar to magnetite/ hematite ore flotation.

Chromite is a member of the spinel group and is the only economically important ore mineral of chromium. It is used extensively by the metallurgical industry as feedstock for ferroalloy production [1,2,3,4].Chromite ore is commonly classified into different grades based on the Cr/Fe ratio as well as the Cr 2 O 3 content. These being metallurgical grade, chemical grade and refractory grade [].

The flotation removal of the remaining coarse quartz tends to make fine iron oxide particles float. When coarse quartz particles are present in large amounts, as in the case of low-grade iron ores, the selectivity of the flotation separation is impaired and the process practiced at the Tilden mine becomes ineffective.

It is well documented that flotation has high economic viability for the beneficiation of valuable minerals when their main ore bodies contain magnesium (Mg) carbonates such as dolomite and magnesite. Flotation separation of Mg carbonates from their associated valuable minerals (AVMs) presents several challenges, and Mg carbonates have high levels of adverse effects on separation efficiency.
