Mining & Minerals Solutions
Durable solutions for extraction, processing, and slurry transport.
Overview
Mining operations subject flanges to abrasive slurries, high-velocity fluid flow, and sustained mechanical stress. Concentrators, flotation cells, and slurry pipelines wear components rapidly. Flanges must balance cost (capital constraints), durability (replacement costs), and availability (remote locations).
Applications
Slurry pump discharge manifolds
Dewatering system connections
Flotation cell inlet/overflow
Concentrator feed line nozzles
Tailings disposal piping
Leach solution circulation
Magnetic separator housing flanges

Typical Service Specifications
Mining flanges operate at moderate pressures (150-600 PSI) with abrasive slurry media at ambient to 180°F. High velocity (6-10 ft/s) demands impact-resistant design. Wear-resistant coatings and robust bolt designs preferred over high-alloy materials in many applications.
