Research Team • Carlos Conca • Rodrigo Demarco • Mauricio Gaggero • Raúl Gormaz • Jorge San Martín • Millaray Sandoval • Miguel Carrasco • Luis Fuentealba • Ramón Fuentes • Enrique Molina
The models Flow model Transport model Chemical model
The models Flow model Flows in porous media. (Darcy Law) We use a comercial software (3FLO) Transport model Chemical model
The models Flow model A solute mix is transported through the flow.We use the Finite Volume method to solve the transport equations. Transport model Chemical model
The models Flow model We model the chemical reactions between the solute and the copper ore in the mineral deposit. Transport model Chemical model
MAIN GOALTo obtaincopper concentrations present in the extracted solution under different operating conditions
Steps of the Chemical Modeling • Copper-Solution reaction • Shrinking core model • Bargain-Solution reaction • In this model we studied the influence of other minerals (Bargain) present in the mineral deposit • Species Computation • Here we study the equilibrium concentrations between the different chemical reactions in the system
