BENEFICIATION OF URANIUM FROM LOW GRADE URANIUM CONTAINING ORES

摘要

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 the slurry medium at a density similar to the feed.
