The HBI direct reduction process - voestalpine
The direct reduction process. HBI is the product of reducing iron ore with natural gas. This is called the direct reduction process and is an environmentally-friendly production process; a DRI plant uses natural gas which is more environmentally sound than coke. The reduction process takes place in the reduction tower.
