Question

Write the names of any two ores of iron.

Answer 1

Hint: Ores are basically raw materials that are required for making metals. Most metals are too reactive to exist on their own in the ground. Instead, they combine with other elements which are called ores. So, to solve this question, we need to know the compounds that are mixed with iron.

Complete step by step answer:
Ores are the minerals from which metals are conveniently and profitably extracted. Some of the ores of iron are hematite, magnetite, siderite, iron pyrites etc. Moreover, among all the ores of iron, magnetite is the finest quality iron ore. So, now let’s discuss the iron ores in detail. First of all, we will discuss the properties of magnetite.
1.It is considered as the finest ore among all the ores of iron.
2.It basically comprises seventy percent of iron.
3.The chemical formula of this ore is $F{e_3}{O_4}$
4.First of all, magnetite is reduced from ferrous oxide and then later, iron is extracted from its oxide.
5.It is the most magnetic of all the naturally occurring minerals on Earth.

The next one is Hematite. Some of its properties are:
1.It is a heavy and relatively hard oxide mineral.
2.Most of the hematite occurs in soft, fine-rained, earthy form called red ochre or ruddle.
3.The most important deposits of hematite are sedimentary in origin.
4.It is found as an accessory mineral in many igneous rocks.

Note: Don’t get confused with ore and mineral. Ore is basically the rock from which the metal is extracted in a convenient and economical way. It has a composition that is definite whereas the metals that occur naturally in the Earth’s crust are known as minerals. The minerals that can profitably be used to get metals are called ores.
