بيت /comparison of various concentration methods in mineral processing
Gravity, Electrical, Magnetic and Seismic Methods . Gravity Methods. The gravity field of the Earth can be measured by timing the free fall of an object in a vacuum, by measuring the period of a pendulum, or in various other ways. Today almost all gravity surveying is done with gravimeters.
