| titleOfInvention | Comprehensive recovery beneficiation method for low-grade uranium-bearing polymetallic ore |
| abstract | The invention provides a comprehensive recovery beneficiation method for low-grade uranium-bearing polymetallic ores, which comprises the following steps: (1) sequentially carrying out forward magnetic separation roughing operation and reverse magnetic separation concentration operation on overflow products obtained by grinding uranium-containing polymetallic ores to obtain iron ore concentrates and first tailings; (2) concentrating and floating the tailings to obtain first concentrate and second tailings, concentrating the first concentrate to obtain lead-silver concentrate, and scavenging the second tailings to obtain third tailings; (3) and carrying out flotation roughing and fine selection on the third tailings to obtain uranium niobium rare earth bulk concentrates. The invention has good beneficiation indexes, realizes the purpose of fully recovering and reselecting all useful components in the tailing discarding coarse-grained rough concentrate under the coarse grinding condition, provides a high-efficiency beneficiation separation and enrichment technology for large-scale development and utilization of low-grade complex multi-metal hard rock type uranium ores in China, and greatly reduces the cost of extracting uranium, niobium and rare earth from the subsequent uranium ores by hydrometallurgy. |
