M&W
Milling & Refining, Inc. is a full service ore
processing facility incorporating custom milling, smelting, refining,
ore testing, and analytical capability under one roof. We specialize in
the testing and processing of precious and base metal ores to insure
maximum recovery in our mill, or flowsheet design to assist in building
your own. Our staff is fully qualified to evaluate the potential of
your ore deposit from exploration to full production, and offer expert
advice at every stage. Our goal is to maximize your profits.
ANALYTICAL: M&W operates a complete analytical facility
including fire assay/ noble metals analysis, atomic absorption and
spectrographic capability, and wet chemical analysis to accurately
assess the valuable minerals in your ore. Our geologists and mining
engineers are available to conduct mapping and sampling at your
minesite, and prepare detailed reports to outline its economic
potential.
BENCH-SCALE
TESTING: M&W is equipped to test your ore by various
processes including gravity, flotation, and leaching by standard
techniques as well as non-cyanide methods, and evaluate recovery
schemes proposed to the client by other metallurgists. Don’t be fooled
by charlatans offering "magical" recovery methods. Our metallurgists
have the background and years of experience to accurately evaluate the
feasibility of any flowsheet. We do not endorse or "peddle" anyone’s
process. Our goal is to provide the client with accurate recovery data
that can be duplicated in the real world, and by other reputable
laboratories. We do not analyze samples for noble metals using ICP.
PILOT-SCALE
TESTING: M&W can provide small-scale production
testing from 100 lb. Lots up to 500 lbs. / hour ball mill grinding
followed by gravity, flotation, or leach recovery. This type of testing
allows the processing of a sample sufficient in size to minimize the
possibility of "salted" samples, and provides a more accurate
assessment of ore grade, to avoid basing a flowsheet on
non-representative or "high-graded" samples submitted for bench-scale
testing, thus insuring that the mill will handle your ore in the real
world.
PRODUCTION-SCALE
MILLING: M&W operates a custom mill capable of
processing 6-10 tons per hour of your ore (144-250 tpd). Our crushing
circuit can produce 30-50 tons per hour of mill feed. The mill circuit
incorporates two-stage grinding using a rod mill and ball mill in
closed circuit with a gravity circuit comprised of Reichert spirals and
a Deister table, as well as a small Gemeni clean-up table. This is
followed by a flotation circuit comprised of a bank of 6 Denver DR No.
21 rougher cells, and a bank of Denver Sub-A cleaners. Concentrates can
be returned to the client, or processed by cyanide leach /
Merrill-Crowe recovery and/or smelting, depending upon the composition
and grade of the concentrates.
PROCESSING
OF CONCENTRATES: The cyanide leach circuit at M&W is
designed to process batches of concentrates or high-grade ore. The
circuit is comprised of two leach tanks having a capacity of 5 tons
each, a thickener, solution storage tanks, and a Merrill-Crowe zinc
precipitation plant. Flotation concentrates amenable to cyanide can
typically be processed at the rate of 5 tons in 48 hours. The zinc
precipitates are then smelted into dore bars.
The M&W
mill is fully permitted for the impoundment of tailings from our
processes, and we work closely with Federal and State agencies to
assure that we are in compliance with all environmental regulations.
REMEDIATION:
M&W has been successfully involved in a number of reclamation and
remediation projects involving major corporations. We are available to
contract or assist in clean-up of contaminated sites using a variety of
technologies. M&W is involved with a spin-off company, Ion
Resolutions, which has recently patented a new process for the clean-up
of mine waste water involving a revolutionary technology for removing
contaminants. Inquire for more information, or visit our website at Ionresolutions
