In the near future bactericides could be used to control acid
generation in leach pads which are temporarily inactive due to market
fluctuations. Maintenance and water - treatment efforts would be
minimized during the shut-down until the economic situation changes,
then the pad could be reactivated.
Presently, - bogs, water treatment facilities, and a host-.of exotic
technologies offer the only - means for treating mine drainage from
underground sources. In the future, bactericides may be ' used to
prevent, rather than treat, deep mine acid waters. An effective means
for delivering bactericides to deep mines needs to be established.-
CONCLUSIONS
ProMac Systems involves the use of controlled release bactericide
to reduce acid drainage problems.and improve water quality as well as
to reduce associated treatment costs in active mining, at preparation
plants, in active coal piles, active refuse piles and mine tailings. . .
The system requires a one-time application that sets up a recovery-
cycle to help nature permanently restore a site with healthy
vegetation. By _ inhibiting acid-producing bacteria, - ProMac Systems
reduces acid formation and aluminum solubilization. It makes the
environment conducive to growth of heterotrophs which are needed for
healthy vegetation, which in turn produces humus and organic acids
detrimental to the acid-producing bacteria. ProMac Systems products
are biodegradable. -
ProMac Systems has been registered by-: the-U.- S. Environmental
Protection Agency under the Federal Insecticide, Fungicide and
Rodenticide Act (FIFRA) for use in controlling acid formation'in
minesoils. --- -- -- ___
Unlike many other . abatement' techniques; ProMac- Systems` is a
preventative strategy- designed.- to- -stop acid problems before- they
develop. _ - - ,•. , f .:. = _.
