Mixer-Settler Solvent Extraction Train

• TI-SX-12 – 12-stage mixer-settler solvent extraction train.
• Multiple trains – a separate train for each metal separation in the flowsheet.
• Section split – extraction, scrub and strip stages arranged to the client's chemistry.

• Stages: typically 12 per TI-SX-12 train, or to client specification
• Flow rates and organic-to-aqueous ratio: sized to the duty, or to client specification
• Extractant and diluent: to the client's flowsheet
• Materials: polypropylene, fibre-reinforced plastic (FRP) or stainless steel, to client specification
• Mixer drives: variable speed, with mixing intensity set for each stage
• Settler sizing: for clean phase disengagement at design flow
• Safety: covered settlers, ventilation, earthing and fire protection for solvent service, to client specification

Mixer-settlers are the standard contactor for separating nickel, cobalt and lithium in battery-recycling hydrometallurgy plants, downstream of leaching and impurity removal. The same design serves copper and cobalt solvent extraction circuits, rare-earth separation and other duties where metals must be pulled out of a mixed solution one at a time.

• Clean separation – generous settler area gives clear phase disengagement and low entrainment.
• Stable operation – each stage runs at its own mixing intensity and interface level.
• Flexible flowsheet – the split between extraction, scrub and strip is set to the chemistry.
• Reduced solvent loss – covered settlers and crud handling limit organic losses.
• Easy access – the open stage layout allows inspection and sampling of every stage.
