    Chargeability¶. The following tables (from Telford et al, 1976) provides a very general guide to possible chargeabilities of materials. One reason that in-situ chargeabilities tend to appear lower than laboratory values is that large volumes of mixed materials are involved in field measurements.

  • Electrostatic Separation Equipment - Mineral Technologies

    Electrical conductivity of most minerals is sensitive to hydrogen (water) content, temperature, major element chemistry and oxygen fugacity. The influence of these parameters on electrical conductivity of major minerals has been characterized for most of the lower crust, upper mantle and transition zone minerals.
