Rejection of Uranium from a Copper Gold Ore by

"Laboratory and miniplant testwork was carried out to reject uranium from an Iron Oxide Copper Gold (IOCG) deposit that contains an average of 60-70 ppm uranium with high variability. The dominate copper bearing mineral is chalcopyrite with minor bornite and trace covellite. The main gangue minerals are iron-rich chlorite, quartz and magnetite.

Preconcentration of Primary Uranium Ores by Flotation

Preconcentration of Primary Uranium Ores by Flotation by Burt C. Mariacher E XTRACTION of uranium from ores is being ac- complished by processes which, for the most part, subject the entire ore to acid or carbonate leaching. Ore deposits with a U,O, content below 0.10 pct U,O, are seldom considered suitable for treatment by leaching.

WO2011161650A1 - Beneficiation of uranium

This invention relates to a froth flotation process to beneficiate uranium economically from both low grade tailings dump ores or high grade ores; by upgrading into a concentrate. The first stage is a sulphide flotation for pyrite recovery, followed by an oxide flotation for uranium recovery. The selectivity of the process for recovery of uranium in the concentrate is enhanced by maintaining ...
