Mining & Minerals
Proven Valve & Control Solutions for the Mining & Minerals Industry
At Valve & Automation, we provide mining and mineral processing valve solutions—from manual isolation to advanced control—for demanding applications across extraction, separation, and refining. From abrasive slurry isolation to aggressive chemical dosing and precise process control, our valves are built for the tough conditions found in extraction, concentration, and refining.
We have a strong track record in high-value mineral refining environments, where zero leakage, chemical compatibility, and uptime are critical. Our Richter fully lined valves and pumps have delivered exceptional reliability in these applications—helping our clients reduce downtime, avoid safety incidents, and extend asset life.
Across platinum, gold, copper, and iron ore operations, we’ve helped plant teams with solutions that:
- Resist corrosion and abrasion in aggressive chemical and slurry services
- Provide accurate control in thickener underflow, flotation, and SX/EW processes
- Lower total cost of ownership by reducing maintenance and improving performance
- Enhance plant safety and environmental compliance
With technical specialists available to assist with valve sizing, material selection, and actuation, we ensure each valve is tailored to your process needs and plant conditions.

Richter Lined Valves & Pumps
Fluoropolymer-Lined for Corrosive Media
The Richter range of PTFE and PFA-lined valves and pumps is ideal for handling aggressive chemicals used in SX/EW, acid dosing, and high-purity refining. Designed to provide long-term corrosion protection and zero leakage, Richter valves offer safe, reliable performance in the most demanding chemical environments.
Key Applications:
- Sulphuric, hydrochloric, and hydrofluoric acid dosing
- Solvent extraction and electrowinning (SX/EW)
- High-purity metal refining
- Chemical containment in reagent prep and handling
Key Benefits:
- Superior chemical resistance with full fluoropolymer lining
- Zero-leakage sealing for maximum safety
- TA Luft-compliant for emissions control
- Available in ball, globe, diaphragm valves and lined centrifugal pumps
NAF-Setball SF – V-Port Ball Sector Control Valve
The NAF-Setball SF delivers precise flow control in tough slurry and chemical handling applications common to mineral processing plants. Its segmented ball design handles thickener underflow, flotation control, and chemical dosing with high accuracy and reliability—even in abrasive, solids-laden media.
Key Applications:
- Thickener underflow regulation
- Froth flotation control
- Chemical and pH reagent dosing
- Slurry flow metering
Key Benefits:
- High control accuracy, even at low flow rates
- Optional hard coatings for abrasive slurry resistance
- Low torque operation, reducing actuator stress
- Compact, short-pattern design simplifies installation
Stafsjö SLV – Fully Rubber-Lined Knife Gate Valve
Engineered for heavy-duty slurry isolation, the Stafsjö SLV features dual full-bore rubber sleeves that completely isolate internal components from abrasive media. Designed for harsh conditions found in tailings, cyclone feeds, and concentrate pipelines, it delivers consistent sealing with minimal maintenance.
Key Applications:
- Tailings and concentrate pipelines
- Cyclone feed isolation
- Thickener and clarifier underflow
- High-solids slurry service
Key Benefits:
- Full bore flow path reduces wear and pressure drop
- Self-cleaning sleeve design maintains sealing performance
- Long service life in abrasive slurry conditions
- Manual or automated actuation options available
