Transport Processes and Separation Process Principles, 5th Edition

Chapter 31. Leaching

31.0 Chapter Objectives

On completion of this chapter, a student should be able to:

• Describe the process of leaching and how it differs from liquid–liquid extraction

• Provide industrial examples of leaching processes

• Explain how the solid’s material structure and the solute solubility can affect the rate of leaching

• Explain the general steps involved in modeling the rate of transfer during leaching

• Calculate the rate of leaching for both solution-controlled and diffusion-controlled processes

• Identify different types of equipment used for leaching processes

• Draw and interpret equilibrium diagrams for leaching

• Calculate solution concentrations using equilibrium diagrams for both single-state and countercurrent multistage ...
