The V-300 Variable Speed Metering System from Fluid Metering (FMI) is designed for drift-free fluid control of lixiviant used in mining pilot plant hydrometallurgy.
Mining Pilot Plants are small scale mining process systems, which generate vital information, which will be, incorporated into the design of larger-scale mining operations. The chemical feed systems used in these pilot plants are not only scaled down as well, but need to accommodate both the rugged environment of a mining operation while possessing the control, versatility, and accuracy typically associated with an R&D laboratory.
FMI’s valveless, ceramic metering pumps have proven ideal for mining pilot plant applications primarily due to the pump’s sapphire-hard ceramic internal components, which are chemically inert, wear resistant, and dimensionally stable. In addition, FMI pump’s unique CeramPump® valveless rotating and reciprocation piston pump design eliminates the need for check valves, which can clog, leak or fail over time. These features result in a pump design which can handle a broad range of chemicals under varying conditions with extreme precision and accuracy.
The V-300 System combines QV Valveless, Variable Speed Pump with the V-300 Control Unit. In the mining industry, the FMI V-300 System is used extensively to pump acids and solvents used in hydrometallurgy in the process area of leaching, as well as solvent extraction. In the uranium extraction process, pumps meter Sulfuric Acid (H2SO4) lixiviant (liquid medium for selective extraction of metal from ore or mineral). A wide variety of solvents are also metered using the V-300 System in the extraction process.
The V-300 Control Unit can accommodate manual control, as well as accept a variety of industry standard electronic control signals from process instrumentation. In addition to electronic speed control, the QV Metering Pump is capable of manual displacement adjustment. The QV is also available in a duplex design (Q2V shown above) featuring independent pump head adjustment ideal for proportional mixing and diluting.
