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/ …
Chromite is one of the main gangue constituents of UG2 ore, 1177 1178 Q.I. Wesseldijk et al. making up 20 to 60% by mass of the ore. Although the main minerals targeted are the base metal sulphides; pyrrhotite, pentlandite and chalcopyrite (Liddell et al., 1986) a certain amount of chromite reports to the flotation concentrate.

Increasingly stringent environmental regulations and industry adoption of waste minimization guidelines have thus, stimulated the need for the development of recycling and reuse options for metal related waste. This book, therefore, gives an overview of the waste generation, recycle and reuse along the mining, beneficiation, extraction, manufacturing and post-consumer value chain.

UG2 ore from the Bushveld Complex is mined in South Africa for its Platinum Group Metal (PGM) content. Two of the main gangue minerals found in the ore are talc and chromite. The PGMs are separated from the ore by flotation. In this process unwanted minerals are also recovered. Talc is naturally hydrophobic and its flotation is depressed by
chromite content and the PGM grade in the concentrate. Froth flotation process is a complex process as all the parameters in the flotation interact with each other. The effects of individual parameters are well studied but interactive effects are less documented for UG2 ore flotation. This study investigated the effect of the interaction of
