  • Flotation Reagents - Mineral Processing Metallurgy

    The flotation reagents can be added in a feed-forward fashion based on the plant raw coal tonnage. Automatic feedback control of the flotation reagent addition rates has been lacking due to the unavailability of sensors for determining the quality of the froth cell tailings. Expensive nuclear-based sensors have been tried with limited success.

  • Copper Nickel Flotation

    The Bureau of Mines investigated the flotation responses of two copper nickel ore samples from the Duluth Complex with the objective of recovering bulk sulfide concentrates. One of the ores studied was taken from a test pit; the other was taken from a test shaft. The samples were quite similar except that the pit sample analyzed 0.35 pct Cu and 0.11 pct Ni and the shaft sample analyzed 0.69 ...

  • Handbook of Flotation Reagents ScienceDirect

    The reagent practice in the flotation of nickel and copper–nickel ores depends on three basic factors: mineralogy of the ore, flowsheet employed in the treatment of a specific ore, and degree of liberation. The presence of hydrophobic gangue represents a major problem in the treatment of both nickel and copper–nickel ores.

  • The Importance of pH in Flotation

    In 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 be ...

  • Froth Flotation Process - Mineral Processing Metallurgy

    The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.
