Choosing a Froth Slurry Pump

Choosing a Froth Slurry Pump

• Froth Slurry Pump - Minerco Solutions for Flotation Challenges Managing the flow of froth slurry can be a major challenge for conventional pumps. The use of strong flotation reagents in hard rock mining creates persistent, stable bubbles that can severely disrupt pumping operations. While oversizing the pump was once a common solution, this approach has its limitations. Instead, using a specialist froth slurry pump - such as those developed by Minerco - is a far more efficient and reliable solution.

• What is a froth slurry pump?
• A froth slurry pump can be centrifugal or positive displacement, depending on the specific flotation process being used. These pumps can be submersible or non-submersible and are designed to handle abrasive, corrosive and high viscosity froth slurries. They are ideal for applications in mineral flotation, coal processing, chemical handling and other demanding industrial environments.
• 
  
• Key design features for frothy applications To ensure optimum performance in frothy environments, several design elements are critical:
• 
  
• Open impeller design: Minimises shear and air entrapment, preserving foam integrity and improving flow.
• 
  
• Enlarged suction flange: Increases slurry exposure to impeller action, reduces inlet pressure differential and prevents air lock.
• 
  
• Suction side relief valve: Releases gas pockets before they reach the impeller, minimising entrained air problems.
• 
  
• Tangential hopper design: Minimises turbulence and allows for longer residence time, allowing air to dissipate before reaching the pump.
• 
  
• Conical hopper shape: Helps direct slurry smoothly into the pump and prevents backflow.
• 
  
• These design elements combine to ensure that Minerco pumps deliver consistent, powerful performance in challenging slurry environments - minimising downtime and increasing productivity in mining and processing operations.
