Keywords: Fluidisedbed, flotation, coarse particles, copper ores . 2 INTRODUCTION For successful flotation to occur, three subprocesses have to happen: collision between particles and bubbles, attachment of the hydrophobic particles to bubbles, and stable attachment of the bubbleparticle aggregate within the flotation cell until reaching the concentrate launder (Dai .

· Subsequently, frothing experiments were conducted with the same copper ores and flotation conditions, modifying the flotation cell and applying a digital photographical method coupled to image analysis. Froth layer thickness and mass of water transferred to the froth volume were measured as a function of pH and solids content, with sea water and fresh water. .

Numerous flotation models have been proposed in the literature. Thirteen of these have been applied to batch flotation data and evaluated with respect to one another using statistical tests were carried out on samples of a US porphyry copper ore (Pinto Valley, AZ). The ore was tested using various collector and frother systems to produce .

All earlier attempts to process the oxidised PGM ores by conventional flotation methods achieved poor recoveries (typically less than 50 %) hindering the commercial exploitation of these resources. The characterisation of the nonsulphide PGM ore used in this study indied that the ore is enriched in oxide iron minerals as a result of weathering. In the flotation work, the .

Flotation columns differ dramatically from mechanical flotation machines in . several ways: • there is no mechanical agitation/shear • the cell is relatively tall and narrow • gas bubbles are generated by sparging • froths typically are deeper, and wash water typically is liberally applied to the ...

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey ParrottSheffer.
