5. 4. Life cycle assessment of coal based direct-reduced iron production in India

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : SABARISH ELANGO; [2020]
   Keywords : ;

   Abstract : The production of iron through direct reduction (Direct-Reduced Iron; DRI) involves the use of natural gas or coal to reduce iron ore to iron through carbothermic reactions at a temperature below its melting point, negating the need for a blast furnace as otherwise required. In India, around 25% of iron is produced through direct reduction. READ MORE
