  • Flotation | ore dressing | Britannica

    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, Research EditorThe behavior of coal in the flotation process is determined not only by a coal’s natural floatability (hydrophobicity), but also by the acquired floatability resulting from the use of flotation reagents The general classification of the reagents for coal flotation is shown in Table 121 (Laskowski, 2001)Flotation Process an overview | ScienceDirect TopicsIn general, in mineral flotation, studies on flotation rheology have been detailed in many aspects including rheological effects on flotation response, influencing variables and rheological measurement techniques, in both the pulp and froth zone In recent years, progress in flotation rheological investigations, especially the froth rheology, has been greatly advanced However, no work isA Brief Review of Pulp and Froth Rheology in Mineral

  • Flotation Principles

    Metallurgical ContentSURFACE TENSIONBULKOILOIL AND AIRBUBBLESCOAGULATIONFROTH Flotation, in its latest phase, is a process of concentrating ores by frothing When crushed ore, previously mixed with water and a relatively minute addition of oil, is agitated violently in the presence of air, a froth is formed This froth, rising to the surface of the liquid mixture, is laden with sulphides orWithin this general macroscopic view of the flotation process as a whole, several distinct micro processes can be identified Each of these plays a role in determining how individual solid particles will respond while they are in a flotation cell Prior to any flotation taking place, a number of detailed chemical processes occur on and exceedingly close to the surfaces of the particles ThisTECHNICAL NOTES 9 FLOTATION Mineral TechIn flotation, pH control is a vital method to control selective mineral separation A standard depressant that is used is an Alkali An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE This is very important The ore may be either alkaline or Acidic To have a positive control over flotation, it is necessary to beThe Importance of pH in Flotation
