Abstract: The condition leaching results of higher column leaching of a deposit of Ganzhou Uranium Mine are summarized in this paper.The results will provide the referece basis for the commercial experiment and research on stope leaching of this deposit.It has been indicated that the Uranium is easily to be leached out and the rules of Uranium concentration,leaching yield and acid consume are distinct followed by different high and different particle sizes.The Uranium extraction yield is 88.9% calculated on leaching solution and 82.1% calculated on residue of the ores minus 50mm;The leaching yield is 67.2% calculated on residue of the ores from 30mm to 50mm;It is 87 8% calculated on residue of the ores from 15mm to 30mm and 90.2% of minus 15mm.
