    Consequently, aside from a few fundamental principles regarding flotation and the use of reagents, it is generally agreed each ore must be considered a problem for the metallurgist to solve before any attempt is made to go ahead with the selection and design of a flotation plant. Types of Flotation Reagents

    This invention relates to the pH modifier in alkaline froth flotation processes to treat oxide and semisoluble salt ores, such as phosphates, sulfates, carbonates and halides, to increase the recovery while generally maintaining or improving selectivity, thus the grade of desired minerals. The invented pH modifier is used to replace

  • Statistical interpretation of flotation kinetics for a

    Correlation analysis suggests that silver flotation is probably determined by the floatability of a separate mineral such as tetrahedrite. Multivariate analysis on pulp chemistry data reveals that the pulp pH is the most significant variable among the pulp chemistry data, provided the grinding is iron free.

    showed that tennantite and tetrahedrite do not respond well to flotation using xanthate as a collector. Tetrahedrite floats well with aerophine and mercaptan type of collectors at a pH value between 8 and 10 [11]. Selective separation of sulphide minerals can be achieved using a variety of collectors and modifiers to adjust surface

  • 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

    PH Modifiers. The role of pH modifier and the dosage affect flotation . From test results, it was confirmed that sodium silicate and other chemicals can be be used with depressant and dispersant could adjust the pH of pulp . Flotation efficiency using pH modifier is better than that using lime in the alkaline conditions (pH 9.511).
