| titleOfInvention | Medium-low grade phosphorite heap leaching method combining composite strain with waste biomass |
| abstract | The invention relates to a method for heap leaching of medium and low grade phosphorite by combining a composite strain with waste biomass. According to the method, according to the characteristics of the medium-low-grade phosphorite and the waste biomass, the medium-low-grade phosphorite and the waste biomass are crushed into powder, mixed, heap-soaked and sprayed with the composite bacterial liquid, cellulose degrading bacteria in the composite bacterial liquid are used for decomposing the waste biomass, a carbon source capable of being directly utilized is provided for heterotrophic phosphorus-dissolving bacteria in the composite bacterial liquid, the medium-low-grade phosphorite is dissolved through the heterotrophic phosphorus-dissolving bacteria, and finally low-cost and large-batch development and utilization of the medium-low-grade phosphorite are achieved. The method has the advantages of strong processing capacity, environmental protection, low cost, simple process flow and the like, and the leaching rate of phosphorus (calculated by phosphorus pentoxide) in the middle-low grade phosphorite can reach over 58 percent after 9 months of heap leaching. |
