Abstract: The test of Liaoning Xinhua low grade Mo ore preconcentration index according to different separation threshold value was studied.The results indicated that preconcentration index varies with the block of feeded material.Under the same test conditions，the beneficiation index of 100~60 mm size class particle was better than the other grain-sized particles and too large or too small particles all can affect the preconcentration index adversely.

Key words: X-ray radiation separator, Classification preconcentration, Separation threshold value
