Abstract: A low grade gold ore from Sultan with poor sulfide was quartz-vein gold deposit.Native gold mainly embedded in quartz minerals as middle and coarse particle size.Column Leaching-activated carbon adsorption experiments were conducted to provide technique basis for the development of the ore.Results indicated that at the feed size of -20 mm，pH value of 10.5～11，concentration of sodium cyanide of 0.10%，spray intensity of 20 L/(m2·h)，leaching time of 16 d，gold leaching rate can reach 73.51%.Comparison tests on abrasion and saturated sorption capacity were conducted on activated carbon A and activated carbon B，activated carbon A has relatively better adsorption properties.With activated carbon A dosage of 8 g/L，adsorption time of 20 h，gold leaching test was conducted on the leaching solution,the gold adsorption rate can reach 99.67%.The results can provide technique basis for the development and utilization of the gold resources.
