Ores Of Some Important Metals and their Composition

Ores of Some Important Metals

Copper ore, ores of element for railways exam and ssc

In this article we will learn about some important Metals and Ores and composition of Ores. Common ores of the elements like Sodium, Aluminium, potassium, etc always ask in the exam.
So let's start about some Ores of the element and their composition.

What is Ores ?

Minerals from which metals can be extracted through various steps conveniently and profitably are termed as ores.

Elements, their Ores and Composition


Elements                                 Ores and Composition


Sodium (Na)       :- Chile salt petre (NaNO3), Common salt or brine (NaCl), Sodium carbonate
(Na2CO3.10H2O)


Aluminium (Al)    :- Bauxite (Al2O3.2H2O), Cryolite (Na3AlF6), Feldspar (KAISi3O8), Corundum(Al2O3), Diaspore (Al2O3.H2O)

Potassium(K):- Nitre or potassium nitrate (KNO3), Potassium chloride (KCl), Carnallite

These are the some element, their Ores and their Composition that always ask in the comptative exams and it will also ask in upcoming RRB NTPC, RRC Group - D and SSC exams. So keep reading , revising my daily article specily created for upcoming Railways exams. I hope it will surly help you in the exam.
