Custom Fabrication of Flotation Machine Components
Precision Steel Fabrication for Mining & Processing Plants
At Openex Metal Fabrication, we manufacture flotation machine components for mineral processing operations worldwide. Our experience includes fabricating structural and mechanical elements such as flotation tanks, stators, rotors, baffles, and launders—each designed and built to withstand aggressive slurry environments and 24/7 operation.
With over 20 years in large-scale industrial fabrication, we apply tight-tolerance machining, heavy-duty plate forming, and robotic welding to produce reliable, long-life components. We work directly from your 2D/3D drawings or collaborate with your engineering team for manufacturability improvements.
Typical Flotation Components We Fabricate
- Tanks & Cell Bodies: Built from heavy carbon or stainless steel, with internal rubber lining or AR plate lining as required
- Rotor-Stator Sets: Machined precisely for turbulent flow and energy efficiency
- Baffles & Launders: Flow-diverting assemblies with coatings for slurry handling
- Support Frames & Mounting Skids: Welded base structures with stress relief and inspection
- Shafts, Couplings & Blades: Custom rotating assemblies machined to spec
