Piping System for Copper Solvent Extraction Plant
Custom-Engineered Piping Solutions for Reliable Copper SX Plant Operations
The piping system for copper solvent extraction (SX) plants is purpose-built to handle organic extractants, aqueous solutions, and acidic raffinate streams used in copper SX processes. Designed for chemical resistance, hydraulic efficiency, and operational reliability, this system ensures smooth plant operation while minimizing downtime and maintenance costs.
SX Process Challenges
Copper solvent extraction plants present unique piping challenges:
- Organic solvents: Extractant and diluent mixtures that can attack certain materials
- Acidic aqueous phases: Sulfuric acid solutions with dissolved copper
- Mixed phases: Emulsions and phase mixtures during transfer
- Large flow volumes: High-volume circulation between mixer-settlers
- Material compatibility: Must resist both organic and aqueous attack
System Components
- Organic Phase Piping
Piping for organic solution transfer between mixer-settler stages, storage tanks and loading/stripping circuits. - Aqueous Phase Piping
Piping for acidic aqueous (raffinate, electrolyte) transfer between leaching, SX and EW circuits. - Mixer-Settler Interconnects
Piping and headers connecting individual mixer-settler units within the SX circuit, designed for proper flow distribution. - Storage & Transfer Lines
Piping for organic and aqueous solution storage tanks, including transfer, recirculation and inventory management lines. - Valves, Pumps & Fittings
SX-compatible valves, pumps and fittings in appropriate materials for complete system compatibility.
