1 Froth Flotation Fundamental PrinciplesDense Medium Separation An Effective and Robust Pre
1 1 Froth Flotation Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in aimpart higher g forces on the particles of both the ore and medium and would cause separation by size similar to the principle of a classification hydrocyclone Classification of the medium would cause density gradients in the cyclone comparable to the particle size gradients present in a hydrocyclone resulting in an ineffective separation

Extraction of iron from Sanje ore by single stage magnetic separation or flotation process did not produce high grade iron concentrate with silica and alumina content This is because Sanje ore has iron mineral particles which are strongly aggregated with silica and alumina and disintegration using single separation technique was difficultIron ore of high phosphorus content coexists with other minerals in the form of apatite or fluorapatite Phosphorus is spread on the edge of mineral particles of iron oxide and embedded in quartz or carbonate minerals and a small amount is present in the iron mineral grid Xia et al

A later example was the Cornish stamps consisting of a series of iron hammers mounted in a vertical frame raised by cams on the shaft of a waterwheel and falling onto the ore under gravity The simplest method of separating ore from gangue consists of picking out the individual crystals of eachgrab the iron particles and the rest is discarded For every ton of iron retained two tons of waste or tailings are discarded process of separating the iron from the non iron material The magnetic iron ore is then the silica and sand Thus the ore is concentrated by removing the waste materials The concentrate from the
