We get minerals and ores in abundance in the earths crust. Some ores have been proven themselves a great resource for mankind. Such as iron obtained from ore of iron (Hematite) built the foundation of industrial revolution. Out of total naturally occurring elements 70% are metals. Metals occur in nature in free as well as in combined states.
Instead, they exist combined with other elements as compounds called ores. Ores are raw materials for making metals. Minerals are those in which individual crystals are composed of unit cells or basic unit layers of two or more types. Minerals are inorganic catalysts that function as regulators of metabolic activities in the body.

Iron Heavy Metal. Iron is a chemical element in the periodic table that has the symbol Fe and atomic number 26. Iron is a group 6 and period 4 metal. Iron is notable for being the final element produced by stellar nucleosynthesis, and thus the heaviest element which does not require a supernova or similarly cataclysmic event for its formation.

Examples of Minerals and Their Uses. Here is a list of minerals which are immensely used to improve our day-to-day lives. Hematite It is a metallic mineral and an iron oxide. Its formula is Fe 2 O 3. It is used to extract iron and is one of the many iron ores. Other iron ores are magnetite, limonite and siderite.
Oxide minerals have oxygen (O 2) as their anion, but they exclude those with oxygen complexes such as carbonate (CO 3 2), sulphate (SO 4 2), and silicate (SiO 4 4).The most important oxides are the iron oxides hematite and magnetite (Fe 2 O 3 and Fe 3 O 4, respectively).Both of these are important ores of iron. Corundum (Al 2 O 3) is an abrasive, but can also be a
Mar 11, 2020 Write the name and formula of the ores of iron. Answer Question 33. Define periodicity. Answer The electronic configurations of elements help us to explain the periodic recurrence of physical and chemical properties.
