  • flow chart of flotation used in mines

    The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining. The smelting stage gives the name pyroprocessing

  • Flotation Circuits Diagrams Mineral Processing &

    17/10/2016· Since several types of flotation circuits can generally be employed in conjunction with the various processes for the flotation of different classes of minerals, an outline of the standard circuits in common use is best given before the processes to which they are applicable are described. The flow sheets illustrating them are diagrammatic, but, in cases where the circuit includes two or more

  • Copper Mining & Extraction Process Flow Chart

    26/08/2015· There are two main process streams; one for sulfide ores and the other for ore that is being weathered to oxidize sulfides the so-called oxide ores. All ore in the pit is drilled and blasted and loaded into trucks and hauled for treatment if the ore is un-oxidized sulfidic ore then it needs to be crushed and milled to a fine slurry then it gets past through flotation cells in a concentrator to separate and

  • Copper Flotation Mineral Processing & Metallurgy

    16/05/2016· The flotation of native copper ores is nearly always preceded by gravity concentration in jigs and tables not only because the combined process is more economical as regards costs, but also because the copper often occurs as large grains which flatten out during grinding and cannot be broken to a size small enough for flotation. The flow sheet depends on the mode of occurrence of

  • Potash Flotation Process Mineral Processing & Metallurgy

    06/05/2016· Flotation has been developed as the principal separating process for the potash salts which generally are coarsely crystalline and free from the sodium salts at about 10 to 14 mesh. In most cases the potash is floated in the froth product and the salt, NaCl, discarded as tailings. A plus 60% K2O product is required and flotation normally will maintain grade at 61 to 62% K2O without difficulty

  • Mineral processing Wikipedia

    In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles. The driving force for this attachment is the change in the surface free energy when the attachment occurs.

  • Advanced process control in mining ABB Digital

    APC manages blending, grinding and flotation in real-time. Geological models and real-time material tracking provide a short-term feed characteristic schedule to the APC so it can increase performance and quality in real-time. In some mines, ventilation accounts for almost 50 percent of energy consumption.

    This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles. The driving force for this attachment is the change in the surface free energy when the attachment occurs. These bubbles rise

  • Flotation Developments & Best Practice International

    04/11/2013· Proper flotation cell level control is one of the most important yet overlooked parameters in a mineral processing plant, especially in new plants, says XPS Process Control. Upstream flow disturbances, improperly sized actuators, poor controller tuning, including dead time between control actions and responses, and improperly selected/commissioned instruments all contribute to the

  • Enhancing Flotation Performance With Process Control at

    ZINIFEX Century Mine is a zinc, lead and silver concentrate producer. Flotation is the primary method of minerals separation in this circuit. The flotation circuit is quite large with 79 flotation cells. The levels in each of these interconnected cells are controlled at more than 45 level control stations. Due to the multivariable interaction throughout the circuit, good level control was found to be difficult to achieve

    Gekko Systems Pty Ltd recognises that the most simple and risk averse route to increasing economic reserves is to reduce cut-off grade in the mine, thereby bringing formerly uneconomic reserves into the economic category. We have been developing a new process flow sheet which embodies the triple bottom line and the issue of economic replacement of reserves. This paper describes this flow sheet
