DR-Grade Iron Ore Pellets - Midrex Technologies,

The supply of DR-grade iron ore pellets always has been tight, but it could become more of a problem with the prolonged disruption of production at Samarco, the addition of HBI capacity to meet growing demand, and the economics of DR-grade pellet production. Some companies building direct reduction plants, such as Cleveland-Cliffs Inc, which has announced plans for a 1.6 million t/y HBI plant using MIDREX® Technology, have their own iron ore

Introduction to Iron ore Pellets and Pelletizing

There are several iron ore pelletizing processes/technologies which are available for the production of the pellets. Some of these are (i) shaft furnace process, (ii) straight travelling grate process, (iii) grate kiln process, (iv) cement bonded processes (Grangcold process, MIS Grangcold Process, and char process etc.), and (v) hydro-thermal processes, (COBO process, MTU process, and INDESCO process etc.). However, at present, only the straight travelling grate (STG) process
