INDUSTRY PRODUCTS
Torrey Pines Scientific, Inc.® Announces Its New
Line of Multi-position Analog Stirring Hot Plates and
Stirrers Featuring 5 or 9 Stirring Positions
The large 12″ (305 mm) square ceramic heater tops have a
temperature range to 450°C. The 5-position stirring units can stir
5-800 ml beakers, and the 9-position units can stir 9-500 ml beakers
of aqueous solutions from 100 to 1500 rpm. Each stirring position
is individually controlled so different vessels can be stirred at
different speeds at the same time on one plate surface.
The Models ST15 Stirrer and the HS15 Stirring Hot Plate can
stir 5 vessels. The ST19 Stirrer and HS19 Stirring Hot Plate can
stir 9 vessels. The units measure 19″ (432 mm) deep by 12.5″ (318
mm) wide by 5.25″ (134 mm) tall. They can support more than 50
pounds (22.6 kg) on the plate surface. All controls are mounted
well in front of the heater surface to protect against accidental
burns, and the units are designed to keep spills out of the chassis.
The units are available in 115VAC/60Hz, 220VAC/60Hz, and
230VAC/50Hz. They have a main AC on/off switch and are fused
for safety. They are supplied with user's manual and detachable
line cord for the country of use. All units are UL, CSA and CE or
equivalent rated.

Fluid Metering, Inc. 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.
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.
FMI's V-300 System combines FMI's 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.
