Hydrometallurgy
Controlling solution chemistry to stabilize metal recovery
The role of hydrometallurgy in mining operations
Hydrometallurgy is a downstream stage of mining operations where metal recovery relies on controlled solution chemistry and predictable separation behavior. Within our mining portfolio, hydrometallurgical support is applied in defined applications—specifically leaching and solvent extraction—where chemistry can reduce recovery risk and improve operational stability, without extending into full flowsheet ownership.
This targeted approach helps mining operations manage variability introduced by complex ores, changing solution conditions, and tighter operating constraints, reinforcing stable recovery performance across connected downstream processes. This capability is selectively deployed today and continues to be expanded through phased validation and customer collaboration.
Why the chemistry matters
Hydrometallurgical circuits concentrate a high proportion of operational and recovery risk. Small deviations in solution chemistry, phase behavior, or impurity control can lead to metal losses, unstable operation, or downstream disruption. As ore grades decline and mineralogy becomes more complex, consistent hydrometallurgical control becomes increasingly important to overall site performance.
• Leaching
Chemistry is applied to support controlled metal dissolution, manage reaction behavior, and reduce variability in defined leaching systems. The objective is to improve consistency and limit recovery risk under variable ore and operating conditions.
• Solvent Extraction (SX)
Chemistry support focuses on phase separation stability and solution behavior in defined SX applications. Stable phase disengagement helps reduce process variability and supports predictable downstream recovery.
