Carbon Fiber Felt will reduce all precious metals in solution, from PH3 to PH 12 in leach or natural aqueous solutions.
This includes natural waters from Flooded Mines, Rivers, Creeks, Ponds, as well as leaching solutions you may be
using to extract metals from hard ores.
The carrying capacity is near 10 kilos per square meter of fabric. This was a lab testing known leaching solutions of
Gold, Silver and Platinum Group Metals. *The loading was obtained using one FSI column filled with a 10’ x 20”
cartridge rolled from this Carbon Fabric, fed by a 40 GPM submersible electrical pump running at full volume, from a
30 gallon tank of the leach liquid, pumped into the top 2” opening and allowed to gravity drain directly out of the
bottom, back into the leach tank.
The full-speed flow is well beyond “normal” suggested flows for carbon (10GPM), yet no loss of metals was observed,
and the leach tank was stripped in roughly 6 hours of recycling this liquid through the FSI setup as described above.
Remaining liquid had less than 1% metals remaining, and the leach kept it’s Chlorine mixture at full strength, at PH 12,
the original mix used to leach the ores.
The ore materials were ground in a ball mill with this leach mixture first, allowed to settle off in a separate tank, then
the clarified leach with dissolved metals transferred to the pumping/recovery tank for the final recovery into the
carbon filter cartridge.
For those presently using heavier Coconut carbon granules, this can significantly improve recovery and reduce
handling costs. These Filter cartridges can be used without the standard FSI insert bags, exercising care to install
correctly.
For filtration from “Natural” sources, this may require pre-filtering to insure only “clean” water enters. For leaching
solutions, these carbon filters will tolerate ALL common Halogen, Halox, SSN, Cyanide and other leach formulas
equally.
Filters, once loaded, can be smelted directly into furnaces, requiring no preparation, and no contaminants result from
this practice. These filters can also be stripped of values, as in the Zadra Process, for electrowinning or other metals
separations. The final wet-chemistry separations can also be directed into additional Carbon Felt filters to collect
these refined values.

No more lost gold or PGM's from abrasion of Carbon particles while collecting, or in the leach tanks during
processing. No more having to "ASH" the carbon to recover values. Bags and Cartridges can go right into Aqua
Regia directly, for near Instantaneous stripping of metals values, or use "Halox" to strip it, albeit slower.
It is Re-usable. We have used many of these dozens of times, with little wear. All parts are acid-and base
tolerant to chemical soups. Water is their natural friend, and can be used at any point of the recovery process...from
natural rivers, to leach streams pumped in commercial circuits.
Electrical Properties. "Super Carbon Fabric" has remarkable electrical properties, capable of being electrified
even further by low voltage, high amperage DC sources, like a 12 volt charger, to collect PM's at rates up to 100
times as fast as conventional carbon particles, made for the gold industry.
