DRI production | International Iron Metallics Association
DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.

The high-pressure acid leaching (HPAL) process of laterite ore was developed in the 1950s. The flowsheet of the HPAL process is shown in Fig. 1.10. The metal elements, including nickel, iron, and cobalt, are selectively leached at high temperature and high pressure.
The six main steps of iron ore processing
Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.
