| Abstract: |
| According to Darcy law, the numerical model for leaching solution seepage in an efflorescent orebody is established. This model is solved by finite element method. The effects of different injection ways, injection pressure, permeability of ore and rock, water storage factors on leaching are considered in 18 models of calculating penetrating flow of leaching liquid through the orebody. Based on the calculation and analysis, drillhole pattern parameters, injection intensity, operation system and possible leakage are determined for in situ leaching. |
