A practical introduction to extracting gold from refractory ores using chlorine solutions.
This edition explains how chlorine-based leaching works, why roasting and oxidation matter, and how to optimize steps from preparation to precipitation.
The text covers the chemistry behind gold chlorination, compares it with other solvent methods, and shows how to design and operate chlorinating plants. It also walks through plant components, from roasting furnaces to chlorinating barrels, filtration beds, and handling of gases and reagents. Clear, applied guidance helps readers understand both the theory and the real-world steps needed for successful chlorination in mining projects.
- How chlorine interacts with gold and why certain pre-treatments improve recovery.
- Equipment and process flow for roasting, leaching, filtering, and precipitation.
- Practical notes on roasting quality, gas management, and safety considerations.
- Strategies to evaluate and optimize recovery rates in different ore types.
Ideal for mining engineers, students, and practitioners seeking a grounded, hands-on reference to the chlorination method.
