What is AMD?
AMD stands for "Acid Mine Drainage.
It is the scourge and legacy of un-controlled mining for minerals in almost every
state in the USA.
Typical of our approach to recovery of Precious metals from riparian sources, we
suggest that a combined approach of selective precipitation of precious metals
from Acid Mine Drainage can be successfully accomplished with our technology, as
well as removal of less-desired contaminant metallics, sediments and debris,
severely reducing undesireable contamination to existing watersheds.
This process begins with "In-Line"precipitation of select metals directly from the
water load, then passed onwards to bulk precipitation in typical flocculation ponds,
to drop out the less-desired metals by wholesale precipitation by alkaline agents
suitable for the area and target recovery goals.
The AMD is pipe-guided to precipitation tankage, the titrated precipitating agent
added, then overflows to a second tankage to meet a flocculant addition, then fed
to a filtering unit, to recover the precipitated metals.
Undesireable metals precipitate out in phase 2, as these waters pass onwards to
the settling pond, where a more broad-spectrum precipitant is added. This is
usually a cheaper PH balancer.
The filtration units are of commercial grade, can be gravity operated if applicable,
then waste waters are passed to a settling pond area, a PH balancer is added in
the circuit, such as water-driven limestone rock tumber, which adds a Base PH
correction, raising PH levels to acceptable levels before entry into the settlement
area, or passed back into the water flow to downstream, as desired.
PH-Ballancing additives depend on local budgets, ecological compatabilty, water
useage, recovery equipment and other factors.
This last phase causes remaining metals to become hydroxides and drop out of the
aqueous stream.
Final polishing of the water can be by our CARBON FIBRE as a blanket "SPONGE" to
absorb remaining, escaping metallics, also re-cyclable.
As an option, our CARBON FIBRE can also be used in Phase 2, in-line in piping or
"leach-tankage", to recover a wider range of metals prior to PH adjustment, and
before settlement or discharge.
These CARBON FIBRE filters can be stripped of metallics on site, or sent onwards
to the refinery for processing, if the profit potential warrants it.
The emphasis here is to act within, and with local agency goals in a cooperative
fashion, obviating any special permitting requirements, assisting in the
improvement of public water quality for the benefit of people and wildlife, alike.

We invite those in remediation and experimental metal recovery technologies to participate in expanding
the body of knowledge.
To participate in ongoing studies or receive more information, please write or call during business hours.
We are happy to work alongside your current efforts to recover precious metals as a way to fund your AMD
requirements.
Those involved with "Trout Unlimited" or similar remediation efforts to re-establish environments should
pass along this information to directors and concerned parties.
Simultaneously, this technology works well with soil and sediment recovery programs emmanating from
present or former mining sites, as our partners in this matter specialize in soil remediation, stabilization of
streams and fish populations, breeding bed renewals, etc.
Please send us your project needs.
