Mixing Expertise by Mineral Segment

Lithium (Lithium-ion Battery Materials)

In the realm of electric vehicles (EVs), the significance of Lithium-ion batteries cannot be overstated. Favored for their remarkable power density and performance, Lithium-ion batteries have emerged as the preferred choice, driving the evolution of clean and efficient transportation. As the automotive industry embraces sustainability, our mixing solutions contribute to the backbone of lithium-ion battery production, propelling the shift towards a greener future.

Support for the full lithium production chain, from brine extraction to lithium hydroxide crystallization or spodumene to spodumene concentrate or lithium carbonate.

 

Key Applications:

  • Conditioning and Scrubbing
  • Solvent Extraction (SX)
  • Brine Impurity Removal
  • Crystallization (LiOH, Li₂CO₃)
  • Reagent Dissolution & Blending
  • Lithium (Lithium-ion Battery Materials)

Gold: Maximizing Recovery, Minimizing Risk

Gold recovery requires precision at every stage, from ore preparation to final purification. Whether operating Carbon-in-Leach (CIL), Carbon-in-Pulp (CIP), or Pressure Oxidation (POX) systems, achieving consistent solids suspension, gas dispersion, and reagent distribution is critical to throughput and yield.
SPX FLOW’s Lightnin and Philadelphia brands are trusted globally across the gold processing value chain. Our robust, high-efficiency mixers are engineered to thrive in the harshest leaching environments, including high-pressure autoclaves and bio-oxidation reactors, ensuring uptime, safety, and long-term performance.

Mixing Solutions for Gold Processing Applications:

  • Carbon-in-Leach (CIL) / Carbon-in-Pulp (CIP)
    Ensure uniform slurry mixing and maximize carbon contact time to improve gold adsorption efficiency.
  • Pressure Oxidation (POX)
    Enable effective oxygen transfer, solids suspension, and gas dispersion in autoclave circuits—even at elevated pressures and temperatures.
  • Biological Oxidation
    Provide optimal conditions for microbial activity with advanced flow control and shear-sensitive agitation.
  • Conditioning & Attritioning
    Promote reagent activation and particle surface cleaning to improve leach kinetics.
  • Detoxification
    Maintain controlled reaction environments for cyanide destruction and effluent treatment.

Copper & Base Metals: Process-Proven Performance

GettyImages-180404741_smallFrom copper to cobalt, nickel to zinc, efficient base metal recovery depends on precise control of chemical reactions and solids suspension. At SPX FLOW, we deliver advanced mixing technologies designed to optimize critical operations like solvent extraction (SX), reagent blending, pre-flotation ore conditioning, ensuring consistent recovery and lower operating costs.

Our Lightnin and Philadelphia Mixing Solutions brands are trusted by leading producers worldwide to provide durable, energy-efficient mixers engineered for long-term reliability in corrosive, abrasive environments. Whether you're operating a large SX train or preparing finely tuned reagent blends, we help you unlock throughput with confidence.

Applications Across Base Metals Processing:

  • Solvent Extraction (SX)
    Ensure high-efficiency phase contact, enhanced mass transfer, and reduced entrainment with custom-designed pumper and auxiliary mixers.

  • Reagent Blending
    Achieve rapid, homogenous mixing of complex chemistries for consistent downstream reaction performance.

  • Slurry Conditioning
    Prepare leach and flotation feed with optimized pH, particle dispersion, and additive distribution.

Mixing Solutions Engineered for Reliability

  • Up-pumping Impeller Technology
    Specifically developed to support critical applications such as auxiliary mixing in SX or gas dispersion and solids suspension in POX circuits.

  • Process Optimization
    Lightnin engineers bring decades of experience in SX circuit optimization for copper, uranium, and rare earth elements applications.

  • Service + Support
    From lab-scale testing to full commissioning, we offer complete lifecycle support, ensuring your process stays online and optimized.
