what is direct flotation in mineral processing

  • Mineral Processing an overview ScienceDirect Topics

    Froth flotation is a long established technique in mineral processing. Extensive discussion of flotation can be found in the book by Leja (1982); see also recent work by Fecko et al. (2005) and Melo and Laskowski (2006). Basically, particles are either hydrophilic or hydrophobic (Gutierrez-Rodriguez et al., 1984). Surface properties of particles are modified with a surfactant (collector). Bubbles, produced by

  • Introduction to Mineral Processing or Beneficiation

    Modifiers are sometimes known as regulators, and are used to vary slurry and mineral conditions to assist in the selective flotation of minerals. Modifiers may activate poorly floating minerals such as sphalerite, or may depress certain minerals, so that a differential flotation can be performed on a complex ore. Chemicals that change the pH of the slurry are also used as modifiers. pH

  • 1 Froth Flotation Fundamental Principles

    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 a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and

  • The importance of rheology in mineral flotation: A review

    01/10/2012· The rheological behaviour of mineral slurries indicates the level of inter-particle interaction or aggregation, and therefore, it can be used as a useful processing control parameter. The flotation separation of minerals may be influenced by inter-particular interactions, and rheological data can offer a direct approach to further understanding these interactions.

  • Froth flotation Wikipedia

    Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

    In mineral processing, flotation is a process used to separate the valuable ore material from the gangue material (the undesired/waste rock) This process relies on the different particle surface properties. The valuable mineral is hydrophobic, mea...

  • Froth Flotation Process Detailed Explanation With

    Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This method of froth floatation is a method of mineral processing in which different minerals are separated selectively. Such ores containing multiple metals such as lead, copper and zinc can be selectively extracted by using froth floatation.
