Froth Flotation Process. Another method of concentration of ores is the Froth Flotation Method. This is the process for concentration of primarily sulphide ores. It has the advantage over gravity separation because it can collect even the extremely fine particles of minerals.Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic conditionthat is, the surfaces are either repelled or attracted by water.The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration plants.In such cases, the separation can be speeded up by aerating the effluent whereby air bubbles are attached to the suspended matter. This has the effect of increasing the buoy ancy of the particles as a result, the particles float to surface from where they can be readily removed. . To aid in the flotation process, chemical coagulants such as .

Concerning the necessary bubble generation method, typically dispersed-air or dissolved-air flotation was mainly used. Various types of biological materials were tested and floated .Flotation is a process of the physical-chemical separation of valuable species from gangue waste material that makes use of surface properties. The process is carried out in aerated tanks cells or flotation columns where the mineral particles are mixed with water and reagents that make the surface of the valuable mineral hydrophobic.A.V. Nguyen, in Reference Module in Chemistry, Molecular Sciences and Chemical Engineering, 2013 Introduction Main Features of Flotation and the Froth Flotation Process. Flotation is a process of separation and concentration of one kind of particulate particles from another by their selective attachment onto the fluid-liquid interfaces. Froth flotation and film skin flotation are the best .After carrying out a froth flotation separation, the products are as shown in Table 1. Using this data, calculate a Ratio of concentration b Metal Recovery c Metal Loss d Weight Recovery, or Yield e Enrichment Ratio Table 1 Graderecovery performance of a hypothetical copper ore flotation process.Flotation is a process in Liquid-Solid Separation technology whereby solids in suspension are recovered by their attachment to gas usually air bubbles, usually with objective of removing the solids from the liquid. The particles most effectively removed are in the size range from 10 to 200 m. The particle-bubble aggregates that are formed have a density less than the suspension itself .
