Iron ore tailings is a material with a high silt content (49.50%) and a considerable amount of fine sand (38.60%), which can be classified as a sandy silt. This characteristic is related to its non-plasticity, since the clay fraction, responsible for soil plasticity, is very small . A predominance of the clay fraction was verified in the other ...

In contrast to most substances, you can also magnetize iron, making it useful in the creation of electric motors and generators. Finally, there certainly aren't any iron shortages to worry about. The Earth's crust is 5 percent iron, and in some areas, the element concentrates in ores that contain as much as 70 percent iron.

Its manufacturing process involves two steps. In the first step, it is casted and cooled as ordinary cast iron and then again it is heated to 1050 o C and soaked in water for long period (several hours or days).. Hence, carbon content is slightly reduced and graphite content is precipitated as temper carbon.

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 (present-day Iraq) between 2700 and 3000 BCE.
