Reforestation
of waste dumps
Wolkem works committedelly towards
leaving the eco-balance
undisturbed and its mining
operations promotes natural
restoration of flora & fauna.
The overburden that covers our
mines is moved to designated waste
dump areas and are then covered
with top soil and re-vegetated
with appropriate afforestation.
When Wolkem began work in the
1970s there were less than 131
trees in the entire mining lease
area. Today there are over a
100,000 trees & flowering
plants, many of which are rare
species, because of our this
mining project and our implanting
awareness to the local habitants
huge forest has come up around our
mining area. The Vraksh Vardhak
(tree plantation) award from the
Department of Forests of Rajasthan
Govt., is testimony to Wolkem's
commitment towards the protection
of forest environment. These green
land restoration efforts during
the working of the mines ensure
that, when the mines eventually
close the mined out area converts
into forest areas or parks. In
fact, Wolkem's mines were one of
the first few industrial mineral
mines in India to achieve ISO14001
certification.
Dust emissions
Dust emissions are controlled
using techniques like wetting the
mine haul roads, covering stock
piles to prevent wind blow. In the
processing plants, dust is
captured by high-efficiency
filters. Continuous assessment and
monitoring ensure dust levels are
maintained below required levels.
Noise levels are also regularly
monitored. Wherever possible noisy
machines are encased in a noise
absorbing enclosure.

Energy
As our mining operations are
located in the hilly terrain of
country sides, we generate 100%
power of our own. At Wolkem
continuous research takes place to
identify ways to increase the use
of renewal energy and find ways to
reduce the consumption of non
renewal energy.
Water
Though the use of water is very
little, but where ever in our
mining and production process
water is used, the water
containing solids such as mineral
particles is channeled into
sedimentation ponds to remove
suspended particles prior to
discharge and this treated water
is either recycled back into the
production circuit wherever
possible or used for plantation or
is released back into the rivers
after meeting all appropriate
quality standards. We also
implement and propagate rain water
harvesting.
Mineral conservation
As Wolkem realizes mineral
reserves are finite, mineral
conservation programs are held and
techniques which ensure maximum
mineral recovery is practiced .
The rejects of the plant process
are upgraded into saleable
products, the mineral rejects at
the mines are stocked piled
separately and not mixed with the
over burden and efforts are made
to find technologies which can
upgrade the quality.
These initiatives are monitored by
an In House Environment Management
Cell.
