1. Introduction. In recent years, steel production has increased significantly to meet the construction industry demands. This has resulted in the generation of huge amount of iron ore tailings (IOT) which are disposed of as waste in landfills, quarries, rivers, oceans, etc. Malaysia produces millions of tons of IOT.
Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine …
Ferrous metals contain iron and may rust. Iron and steel can corrode – this is known as rust. Rust is a compound called iron oxide and is formed when iron and oxygen react in the presence of moisture or water. Most ferrous metals are magnetic.

3. Flotation - The powdered ore is placed into an agitated and frothy slurry where some minerals and metals based on physical and chemical properties may either sink to the bottom or may stick to the bubbles and rise to the top thus separating the minerals and metals from the waste. 4.
Physical properties. Pure iron is a silvery-white metal that's easy to work and shape and it's just soft enough to cut through (with quite a bit of difficulty) using a knife. You can hammer iron into sheets and draw it into wires. ... Inside the furnace, the iron ore reacts chemically with coke (a carbon-rich form of coal) and limestone.
Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia …

2. IRONPure iron is a metal It oxidizes readily in the presence of oxygen and moisture. In order to obtain metallic iron, oxygen must be removed from naturally occurring ores by chemical reduction. The properties of iron can be modified by alloying it with various other metals (and some non-metals, notably carbon and silicon) to form steels.
Characteristic Physical Properties of Ore Minerals In this section we briefly discuss the most common characteristic properties of ore minerals that are used to distinguish them in reflected light. 2.1. Hardness There are numerous ways of estimating hardness in polished surfaces. The relative
What is iron ore? Iron ore is a mineral substance that generates metallic iron (Fe) when heated with a reductant. Iron ore generally comprises iron oxides, the primary forms of which are …
Pelletization is the process of making spheres of uniform quality iron ore with high carbon content. Iron ore is pelletized so that it can efficiently flow through a blast furnace for smelting. The process involves mixing iron ore fines with additives like limestone, dolomite, and bentonite. This mixture is then formed into balls on a balling ...
Iron (Fe), chemical element and one of the transition elements, the most-used and cheapest metal. Iron makes up 5 percent of Earth's crust and is second in abundance to aluminum among the metals. Iron, which is the chief constituent of Earth's core, is the most abundant element in Earth as a whole.
