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 ISO14001:1996 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.
