3
Flow model Transport model Chemical model The models

4
Flow model Transport model Chemical model The models Flows in porous media. (Darcy Law) We use a comercial software (3FLO)

5
Flow model Transport model Chemical model The models A solute mix is transported through the flow. We use the Finite Volume method to solve the transport equations.

6
Flow model Transport model Chemical model The models We model the chemical reactions between the solute and the copper ore in the mineral deposit.

7
MAIN GOAL To obtain copper concentrations present in the extracted solution under different operating conditions

8
1.Copper-Solution reaction Shrinking core model 2.Bargain-Solution reaction In this model we studied the influence of other minerals (Bargain) present in the mineral deposit 3.Species Computation Here we study the equilibrium concentrations between the different chemical reactions in the system Steps of the Chemical Modeling
