Course Summary

Introduction

Precipitation of Leach Solutions is the fourth in a series of four hydrometallurgy courses by the author, written for university students as well as practicing engineers and metallurgists.

The Hydrometallurgy series covers the elementary theoretical basis of solution chemistry, the engineering aspects, and the technical applications for a large variety of raw materials, e.g. metals, oxides, sulfides, phosphates, silicates, and others. It also covers the purification-concentration steps such as adsorption on activated charcoal, ion exchange, and solvent extraction. Finally, the general aspects of precipitation from aqueous solutions are covered with numerous examples. The series is characterized by clear and simplified flowsheets, numerous chemical equations written mainly in ionic form, many illustrations for equipment and plants, and finally a lucid style presenting the facts point by point as concisely as possible.

Hydrometallurgy 4 - Precipitation of Leach Solutions covers physical precipitation, the principles of crystals and crystallization, and engineering aspects and applications. It also covers chemical precipitation and the principles of ionic and hydrolytic precipitation as well as precipitation by reduction.

Content

The course comprises 18 learning sessions, each of 30 - 60 minutes duration, plus supporting figures, tables, images and references, and interactive reviews that confirm achievement of the learning objectives. The total duration of the course is estimated at 15 hours.

Learning Outcomes

  • Discuss and apply physical precipitation, the principles of crystals and crystallography, and engineering aspects and applications.
  • Discuss and apply chemical precipitation and the principles of ionic and hydrolytic precipitation as well as precipitation by reduction.

Recommended Background

  • First year university level physics and chemistry.
