Two Beneficiation plants, the biggest of their kind
have been established at Costi and Sirigao to process the ore to a high
grade. The technique utilizes primary grinding followed by two stages of
hydrocyclonization. The plants were designed by Lurgi-Chemie, West Germany.
The imported equipment was supplied by Voest Alpine, Austria. Each plant
transforms low grade iron ore contents of 60.5%Fe into high grade iron
of iron ore of plus 67% Fe with a capacity to produce 1 million tonnes
of high grade concentrates per annum. A third Beneficiation plant at Tudou
has state-of-the-art Beneficiation technology that has far greater value-addition
capability. This plant transforms low grade iron ore contents of less than
40% Fe into high grade of iron ore of plus 67% Fe with a capacity to produce
0.5 million tonnes of high grade concentrates per annum.
Central Workshop, Khandepar.
This is the only full-fledged workshop of its kind
in Goa with ISO 9002 certification. It is an indispensable centrally located
workshop that undertakes major overhauls, repairs and engine overhauls
of Earth Moving Equipment. It also reconditions undercarriages and heavy
components. And thanks to its central location, makes co-ordination with
the mines smoother. It has the capacity to cater to outside jobs as well.
Transportation
The processed/finished ore needs to be carried from the mine pits to the river-side
loading points near the mines and subsequently to Mormugao Harbour. The Company
maintains a full-fledged fleet of self-propelled barges of 650 to 1500 tonnes
capacity. Plus a fleet of 10T capacity Tipper Trucks for carrying ore from mine
pits to the river-side loading points.
Transhipment
An innovation in the technique of Transhipment is 33,000
DWT transfer vessel MARATHA DEEP which boosts iron ore exports by enabling quicker
dispatch of vessels. The MARATHA DEEP has a system of mechanical loading with
belt conveyors. It picks up load from the barges with the help of cranes and
then transfers it into the vessels by Belt Conveyors. The MARATHA DEEP feeds
vessels at a speed of 20,000 tones per day, necessary for the mammoth bulk carriers
used today.
