  • 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

  • Mineral processing Wikipedia

    Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue

  • Introduction to Mineral Processing

    The air bubble and mineral particle rise through the pulp to the surface of the froth or foam that is present on the flotation cell. Even though the air bubbles often break at this point, the mineral remains on the surface of the froth. The mineral is physically separated from the remaining pulp material and is removed for further processing.
