Weir Minerals, a leading supplier to the global mining industry, showcased its family of Warman® Froth Pumps, specifically designed to handle heavy froth and dense slurries in the flotation process at International MINExpo 2012 in Las Vegas.
“No two mining operations are alike. The only commonality is the harsh environment of moving abrasive materials from the ground through a processing facility,” said Geoff Moore, Divisional Sales and Marketing Director from Weir Minerals. “Improving mine efficiency and removing more minerals from raw material are challenges mine operators face daily. The Warman Froth Pumps are designed specifically for harsh mining environments.”
A byproduct of the mining process is froth, which is fine particles that combine with air to create a dense material that can bind a standard pump. A stable pump can maintain a consistent flow-rate of raw material through the process, but it has to manage the flow of froth. Too much froth, and the pump can air lock, stopping production.
The Warman Froth Pumps are designed with a large oversized inlet with unique impeller inducer blade that can handle heavy froth and higher viscosity dense slurries with ease.
Since every mining site has unique raw materials with specific properties it is important to select the right froth pump to use due to the fluctuation in the Froth Volumetric Factor (FVF), the volume of froth produced. The Warman Froth pumps were designed to meet the changing demands of a mine.
Design features of the Warman Froth Pump:
- Existing Warman AH series pumps can be converted with only a few modifications
- Standard froth pumps from the Warman AHF, LF, MF ranges for Froth Volumetric Factor (FVF) up to 1.8
- Upgraded froth pump AHF, MF, LF with Continuous Air Removal System (CARS) for FVF up to 4.0
- An inducer blade impeller for positive froth feed
- Enlarged high efficiency slurry throatbush to maximize the inlet size and reduce NPSH required
- Available in various discharge sizes
The cost of operating a mine has steadily increased the last 20 years. As a result, mine operators are investing in products that are higher quality and last significantly longer than previous technology. With its new Material Matters strategy, Weir Minerals focuses on maximizing efficiency and productivity, while maintaining the safety for mine operators in the field.
Providing the durability and strength for extended service life the Warman Froth Pump is another example of Weir Minerals Material Matters strategy.
“You get a lot more out of a product from Weir Minerals. The reason is simple. We put a lot more into it. We go the extra mile — with our metallurgy, with our R&D, with our testing, with our support service. Our froth pumps go well beyond industry standards. It matters what we do. Every part of every product, every little thing, every step of the way. Because in the long run, it all matters,” added Robb Clawson, VP Marketing Communications for Weir Minerals.
