Ore Grinding Density

Coating clearly yields the most accurate result with regard to the real density of ore in-situ in the mine or in a dry crushing circuit, but for grinding calculations where the ore is in continuous contact with water, the pycnometer, astm d 854 and dawson methods are more relevant. standard comminution tests
