Cast Iron is usually extracted from its oxide ore (haematite). It involves the following steps--- 1) Concentration: The ore is first crushed and crushed ore is concentrated by gravity separation; ie hydraulic washing 2) Calcination: The concentrated ore is calcined, ie, heated strongly in limited supply of air in a reverberatoryfurnance.

The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite, limonite or siderite.Hematite is also known as "natural ore".

Iron ore pellets are marble-sized balls of iron ore that are fused with clay for transportation and used in steel manufacture. The process of making pellets from iron ore is called pelletizing. The manufacture of steel from low-grade iron ore involves processes like mining, crushing, separating, concentrating, mixing, pelletizing, and shipping.

For example, iron and steel are made from iron ore. There are mainly four metallic ores – oxides, sulphides, carbonate ores, and halide ores. The three basic steps to extract metal from ore are concentrating or enriching metallic ores, extracting a metal from a concentrated ore, and refining the impure metal and metal compounds.
