2. MINE WASTE UTILIZATION
ABSTRACT
In this case study we address and review the status of
phytoremediation as a technology to reduce and control
contaminated mine wastes. Several different approaches and
different plant species are used to remove environmentally
toxic metals from mine waste sites. Such approaches have the
objective of restoring mining waste sites to human and animal
use, or at least, to curtail or eliminate the off-site movement of
toxic entities that potentially could reach humans. We conclude
that Phytoremediation is a low cost and eco-friendly remedy for
the treatment of heavy metal wastes in the environment.

5. What is phytoremediation?
Phytoremediation –is defined as the use of green metal accumulating
plants for removal of heavy metal from soil as well as water.

7. USES OF PHYTOREMEDIATION
 Remediation of different media:
 Air
 Soil,sediments.
 Ground water.
 Wastewater streams
-industrial
-agricultural
-municipal,sewage.

8. Metal
Phytoextraction
Phytodegradation
Rhizofiltration
CLASSIFICATION OF PHYTOREMEDIATION

9. Phytoextraction
Plant roots uptake metal
contaminants from the soil.
Once the plants have grown and
absorbed the metal pollutants they
are harvested and disposed off safely

10. Phytodegradation
Phytodegradation is also known as
phytotransformation.
It is the breakdown of contaminants
taken by the plants.

11. Rhizofiltration
It is concerned with the remediation of contaminated groundwater
The contaminants are either adsorbed onto the root surface or are
absorbed by the plant roots
Chernobyl - sunflowers
were grown in radioactively
contaminated pools

12. Advantages of Phytoremediation
 Cost effective when compared to other more
conventional methods.
 “nature” method, more aesthetically pleasing.
 minimal land disturbance.
 reduces potential for transport of
contaminants by wind, reduces soil erosion
 hyperaccumulaters of contaminants mean a
much smaller volume of toxic waste.
 multiple contaminants can be removed with the
same plant.

13. Phytoremediation project(1997)
 Mississippi site
Groundwater polluted with TNT pumped through constructed
wetland.
RESULTS:
95% reduction in TNT

14. Current status of phytoremediation
 9 purely phytorem. Companies.
 7 constructed wetland companies
 >40 consulting/engg. Companies that also do
phytoremediation
 ~200 field projects
-founded mostly by EPA,DOD,DOE
-some commercial/joint projects

15. Our Recommendations for Indian
Mines

16. CONCLUSION
Phytoremediation , which makes use of vegetation to remove,
detoxify, or stabilize persistent pollutants, is a green and
environmentally-friendly tool for cleaning polluted soil and
water. The advantage of high biomass productive and easy
disposal makes plants most useful to remediate heavy metals
on site. We conclude that Phytoremediation is a low cost and
eco-friendly remedy for the treatment of heavy metals in the
environment.
