Mining - Phosphate

The major activity of RSMML is the mining of Rockphosphate ore. It operates one of the largest and fully mechanised mines in the country at Jhamarkotra, 26 Kms. from Udaipur and Kanpur Group of Mines located 15 Kms. from Udaipur.

In India the economy being predominantly based on agriculture, the fertiliser production plays a pivotal role. Only about 35% to 40% of the requirement of raw material for phosphatic fertilser production are being met through indigenous sources and the rest is met through import in the form of rock phosphate, phosphoric acid & direct fertilisers. In such a situation Jhamarkotra plays an important role by contributing 98% of rock phosphate production of India.

Rock Phosphate mines at Jhamarkotra & Kanpur Group of Mines are complex deposits. Mining these rock phosphate deposits is far more difficult than that in most parts of the world. Despite the complexities of the deposit, excellent results have been achieved by continuous innovations. With an annual rock handling of about 20 million tonnes, Jhamarkotra is probably the largest open cast mine in India outside the steel and coal sectors. On technical fronts the problem of ground water had affected the mining operations, until an effective dewatering scheme was evolved and implemented. The geometry of the ore body i.e thin and sharply dipping had resulted in long and narrow pits with great depth extension, which involves very high stripping ratio with high lead and lift for waste and mineral. Despite all these problems Jhamarkotra project could sustain the very difficult periods because of its commitment towards scientific approach for exploitation of the deposit with planned development of the pits.

The open pit mining method is being followed at Jhamarkotra Mine  for exploitation of the mineral. The working levels are kept dry by continuous pumping of ground water through tube-wells constructed on periphery of the pit limit.
