Sponge Iron

Manufacturers Association

The Sponge Iron Manufacturers Association (SIMA) established in 1992 is an all India apex body of Indian sponge iron industry. It is the voice of the indian iron ore based sponge iron & steel industry, at both domestic and global forums. As a not-for-profit society, SIMA has been mandated to communicate the viewpoints of its constituents & al stakeholders and represent their interest.


Indian Sponge Iron Industry which was started as late as in 1980’s has come a long way. Today India is the largest sponge iron producer (30 MT in FY 2018) in the world for last 16 consecutive years and contributes about 30% of the world production.

Sponge Iron / DRI

Sponge Iron also called Direct reduced iron (DRI), is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1200 °C).


  • Coal Based Sponge Iron / DRI

    Sponge iron produced using the non coking coal is called coal based sponge iron / DRI. For producing the sponge iron through this process requires high grade of iron ore and non coking coal.

  • Gas Based DRI / HBI

    In this process route, iron oxides are converted to the DRI / HBI by using natural gas in a vertical shaft furnace. For steel producers, it is a preferred metallic, energy efficient and much more eco-friendly route. The product on this route is DRI lumps and in the briquetted form.

SIMA LATEST EVENTS/WEBINARS

SIMA and TERI are jointly organizing a

“Workshop on Energy Saving Opportunities and Pathways for Low-Carbon Opportunities in Indian DRI”

sector on 16th August, 2021 from 11.00 a.m. to 12.30 p.m.

TERI and SIMA have also joined hands to document the energy saving opportunities and possible futuristic options for sustainable growth of the DRI sector. A technology compendium for energy efficient technology options in the DRI sector has been prepared as a ready reckanor for the sponge iron industries. During the workshop this compendium will also be released.

The objective of the workshop is to discuss various options that can help improve energy efficiency of existing DRI units and outline the pathways that can help in the future growth of DRI .
