India's leading producer of Iron Ore | Vedanta Group …
Sesa Goa Iron Ore, a Vedanta Group company, is engaged in the exploration, mining, and processing of iron ore. The company was founded in 1954, as Scambi Economic SA Goa. Since then, it has grown to be one of the country's top low-cost producers of iron ore. During 1991-1995, it diversified into pig iron and metallurgical coke manufacturing.
Direct Reduced Iron Industry in India — Problems and …
About 75% of the sponge iron capacity in India is coal based. While setting up the plants, it has been assumed that iron ore and coal are available easily as India has the fourth largest reserves of iron ore and non-coking coal is available in plenty. Contrary to this, the major problems faced by the sponge iron producers relate to raw materials.

Rotary Drilling
November 1, 2011. Rotary drilling uses a sharp, rotating drill bit to dig down through the Earth's crust. Much like a common hand-held drill, the spinning of the drill bit allows for penetration of even the hardest rock. The idea of using a rotary drill bit is not new.
Comparative Costs of Drilling
In original terms, the largest fall by minerals sought came from expenditure on iron ore exploration (down 14.1% or -$43.9m), with the largest fall occurring in Western Australia. The next largest fall came from expenditure on coal exploration (down 18.5% or -$40.2m).

Common Types of Mining Equipment Used in the Mining …
5. Rotary Drill Rigs and Rock Drills. Rotary drill rigs create holes through rock or soil, allowing placement of charges for blasting open mines. A rotary drill rig is one of two main types of drills used for mining. The other type is a percussion or hammer drill. For a rotary drill rig, the drill bit turns under pressure to cut into the rock.
BlastHole Drilling Introduction
The drilling principle is to use a high pull down force (weight-on-bit), rotate the drill bit, and blow the rock cuttings to the surface with compressed air. Hardrock drills typically use the Rotary method to drill blastholes from 200 mm (7 7 /8") to 311 mm (12 ¼") diameter. Hardware.
