Larox Pumps for Lead and Zinc Analyzing
A Western U.S. Mine producing Lead and Zinc has undergone a major expansion on their Rougher/Scavenger Analyzing and Column Control Processing System. They have chosen Larox Flowsys and the LPP-T as the pump of choice. The total project was worth $125 K.

Process parameters are Lead and Zinc, 30% solids with a specific gravity of 1.4. Two LPP-D25 peristaltic pumps are installed to feed Outotec, type 5SL Courier Analyzers. These pumps run at a fixed speed and continuously feed the Lead and Zinc to the Outotec Analyzers at 1.8 m3/h. Four LPP-T65 units are also installed at this site to pump the Lead/Zinc Scavenger/Rougher Tails solids to a cutter system for the LPP-D25 pumps to feed the Outotec Slurry Analyzing system.
The LPP-T65 pumps run by a VFD system and the flow fluctuates between 1 - 15 m3/h to maintain the cutter systems set level so the LPP-D pumps can monitor the specific plant parameters through the Outotec 5SL Analyzers.
The Larox pump was chosen over the competition due to its numerous benefits such as
This customer has also purchased Larox PVE control valves for column control for the scavenger units. The valves control the level of the columns to retain a high recovery yield of the product.
