Sponge iron is obtained by direct reduction of iron ore with a grade of 84 to 95%. Regeneration removes or eliminates oxygen in the iron ore and turns the stone into a honeycomb or a porous spongy structure, which is why it is called sponge iron. Sponge iron as an intermediate product is mainly used in steel production.

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.

Iron is mainly extracted from hematite (Fe 2 O 3) and magnetite ores. Natural or direct shipping iron ores contain between 50-70% iron and can be fed directly into the blast furnace. Fe 3 O 4 decomposes when heated to ferrous oxide (FeO) and ferric oxide (Fe 2 O 3) via Fe 3 O 4 → FeO + Fe 2 O 3. A specialized type of coal, called hard coal ...
