Abstract: The Waitoushan ores were used as the experimental material.The comminution parameters are obtained by using JK Drop Weight Test and Bond ball mill index test.The results show that the impact comminution parameters A=65.53，b=1.06，A×b=69.46，the abrasion comminution parameter ta of the abrasion crushing test is 0.72.The relative density of ores obtained by relative density measurement is 3.31.Bond ball mill work index is 7.64 kWh/t by corresponding Bond ball mill work index test.The results of Comminution parameters and Bond ball mill work index indicate that Waitoushan ores belong to the category of soft ores，both its impact crushing resistance and abrasion resistance are weak，there are no hard grinding particles in the ores.
