| Abstract: |
| Uranium column bioleaching experiments with 9 kg packing were carried out with additional pyrite (size of -3 mm and purity of 41.64%) from low-sulfur and high fluoride-bearing uranium ores. Three columns include: minerals(9 kg) plus pyrite(1.5%) with culture, minerals(9 kg) with culture, and minerals(9 kg) plus pyrite(1.5%) with no culture. After 80 days irrigation, uranium leaching rates in slag are 90.00%, 88.50% and 77.20% respectively, acid consumptions are 3.97%, 4.05% and 3.95%, respectively. Uranium ores bearing with high fluoride and low pyrite can be treated efficiently with additional pyrite and adaptive mixed culture. |
