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.

In the former process, iron ore is the main raw material. In an electric furnace, scrap iron is used and occasionally also sponge iron. Sponge is an intermediate product, which is produced from iron ore by means of direct reduction (= DRI or directly reduced iron) and that is then further reduced and smelted in an electric furnace.

The first step of physical beneficiation is crushing and grinding the iron ore to its liberation size, the maximum size where individual particles of gangue are separated from the iron minerals. A flow sheet of a typical iron ore crushing and grinding circuit is shown in Figure (based on Ref. [4]).This type of flow sheet is usually followed when the crude ore contains below 30% iron.

It's a long process which begins with Concentration through calcination roasting. Concentration removes the water and other volatile impurities such as sulphur and carbonates. This concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.

Abstract The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking.

Iron processing Ores, Smelting, Refining: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed ironbearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which ...

Slight benefit is that you now get 3 iron ore, 1 copper, 1 quartz, 1 nickel ore, and now 1 titanium ore. Last step is refining. Refining requires 4 crystals (so now, its 2 crush cycles to 1 refine cycle) and produces 4 purified chunks. Sorting requires 9 purified chunks, which means 3 refine cycles, which means 6 crush cycles.

The raw materials mix or "charge" enters the furnace from the top and hot air is blown or blasted from the bottom causing the coke to burn and the oxygen to combine with carbon in the coke to form carbon monoxide. Now, this carbon monoxide that is unstable, reacts with the ore to form carbon dioxide and iron. The Separation Of Iron.

iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand.
