Jun 18, 2024 · Ferrous minerals are metallic minerals that contain iron and are magnetic. They are dark and heavy and generally crystallize at high temperatures and pressures. India possesses abundant reserves of iron ore, with significant deposits in states like Odisha, Chhattisgarh, Karnataka, and Jharkhand.
2 days ago · Iron is a chemical element. It has symbol Fe (from Latin ferrum 'iron') and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core.
Jun 13, 2024 · Ferromagnetism is a kind of magnetism that is associated with iron, cobalt, nickel, and some alloys or compounds containing one or more of these elements. It also occurs in gadolinium and a few other rare-earth elements.

5 days ago · These key minerals exhibited record production levels in FY 2023-24, with production of iron ore at 275 million metric ton (MMT) and limestone at 450 MMT in FY 2023-24. Continuing the trend, the production of these key minerals in the country has exhibited robust growth in FY 2024-25 (April-May) as per provisional figures.
Jun 26, 2024 · Accessory minerals present in igneous rocks in minor amounts include monazite, allanite, apatite, garnets, ilmenite, magnetite, titanite, spinel, and zircon. Glass may be a major phase in some volcanic rock but, when present, is usually found in minor amounts.
1 day ago · Stainless steel, also known as inox, corrosion-resistant steel ( CRES) and rustless steel, is an alloy of iron that is resistant to rusting and corrosion. It contains iron with chromium and other elements such as molybdenum, carbon, nickel and nitrogen depending on its specific use and cost.
2 days ago · It is one of only four elements that are ferromagnetic at or near room temperature; the others are iron, cobalt and gadolinium. Its Curie temperature is 355 °C (671 °F), meaning that bulk nickel is non-magnetic above this temperature.
