Lesson 2: Mineral Dissolution and Precipitation



This lesson introduces reaction kinetics of mineral dissolution and precipitation and how to set up simulation in well-mixed batch reactors in CrunchFlow.

Learning Outcomes

By the end of this lesson, you should be able to:

  • Understand the importance of mineral dissolution and precipitation;
  • Understand the rate laws and kinetic parameters for mineral dissolution and precipitation;
  • Simulate mineral dissolution and precipitation in well-mixed batch reactors in CrunchFlow;
  • Understand how reaction kinetics and thermodynamics control mineral dissolution and precipitation in different ways.
