In their representation to Gandhis, the manufacturers through industry body KISMA said that 28 sponge iron plants, out of 53, have closed for want of iron ore and remaining are running at a capacity utilisation of 27 per cent only.
The integrated steel plants are also running at a very low capacity of 60-70 per cent, the Karnataka Iron and Steel Manufacturers' Association (KISMA) said.
It may take another 2-3 years for getting all the miners operational, but by then the iron and steel industry will face "irreparable losses and may close down permanently" affecting the socio-economic balance of the region and the country, KISMA said.
Copies of the representation have also been sent to Prime Minister Manmohan Singh, Union Ministers Beni Prasad Verma and Dinsha Patel, Karnataka Chief Minister Siddaramaiah, Planning Commission Deputy Chairman Montek Singh Ahluwalia and other senior officials of the Centre and state.

The Supreme Court, while lifting the mining ban on the state, had capped total annual iron ore production at 30 MT. The court had allowed 115 mines to resume production, subject to conditions as set by the Central Empowered Committee (CEC).
Of the miners in Karnataka, state-owned NMDC was allowed to mine 12 MT annually and rest were to come from private producers. Accordingly capacities of the private producers were revised and reduced by the CEC. However, so far only 21 mines, amounting to annual production of 9.7 MT, have resumed production.
It will help the Karnataka iron and steel industry in securing iron ore and running its plants at optimum levels, KISMA further said, adding that environment and carrying capacity principle, as envisaged by the apex court, will remain intact.
The already operational 21 mines had production capacity of 30 MTPA iron ore before the ban was imposed, it said.
