The main metal minerals in a certain gold ore from Liaoning was pyrite,the main gangue minerals were quartz,feldspar and biotite etc.The recoverable elements in the ore were gold and silver,The con-tent of impurity arsenic was little.The index of gold grade of concentrate being 95.53 g/t and the silver grade of concentrate being 836.0 g/t,gold recovery being 82.03% and silver recovery being 78.57% has gotten by floating the ore of crude grade with gold and silver being 1.70 g/t and 15.34 g/t on the condition of grinding fineness being 97.9% of -0.074 mm and using sodium carbonate as pH adjustor,butyl xan-thate and ammonium dibutyl dithiophosphate as collector.
