coefficients for copper ore

  • Extraction Of Copper

    The percentage of copper in the actual ore is too low for direct extraction of copper to be viable The concentration of ore is required and it is done by the Froth Flotation method Concentration of Ore: The ore is crushed into a fine powder and a suspension is created in water To this are added, Collectors and Froth Stabilizers.

  • Friction

    Coefficient of friction The coefficient of friction (COF), often symbolized by the Greek letter µ, is a dimensionless scalar value which describes the ratio of the force of friction between two bodies and the force pressing them together The coefficient of friction depends on the materials used; for example, ice on steel has a low.
