Valveless, Ceramic Pumps for Mining Pilot Plant Hydrometallurgy
The V-300 Variable Speed Metering System from Fluid Metering, Inc. (FMI) is the Solution 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.
FMIs valveless, ceramic metering pumps have proven ideal for mining pilot plant applications primarily due to the pumps sapphire-hard ceramic internal components, which are chemically inert, wear resistant, and dimensionally stable. In addition, FMI pumps 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.
FMIs V-300 System combines FMIs 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 ur...
FMIs V-300 System combines FMIs 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, FMI 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.
In addition to applications in hydrometallurgy, FMI pumps are used extensively in mining operations worldwide for metering surfactants applied for dust suppression. The precision of FMI pumps, especially at very low flows make them ideal for laboratory analysis of mined minerals and ore as well.
For over 55 years Fluid Metering pumps have been used in pilot plant operations, as well as applications which require precision fluid control in medical, analytical, pharmaceutical, water & wastewater treatment, food, semiconductor, alternative energy, environmental monitoring, and much more.

Precision, Valveless Metering Pumps for Low & Micro-Volume Fluid Control
From R&D applications in the laboratory to small scale pilot plants, a broad array of low flow and micro-fluidic applications rely on precision dispensing or chemical metering of fluids. But, as diverse as the applications, so are the variety of fluids, their chemical and physical characteristics, as well as the specific application parameters. For the purpose of this article, we will designate low flows as those below 1 liter per minute (L/m) all the way down to just a few milliliters per minute (mL/m). Micro-volume flows range from microliters per minute (uL/min) up to a few mL/min.
