[amp_mcq option1=”Copper” option2=”Manganese” option3=”Iron Ore” option4=”Chromite” correct=”option3″]<\/p>\n

The correct answer is: c) Iron Ore.<\/p>\n

Iron ore is the primary raw material used to make iron and steel. It is a rock or mineral that contains iron. Iron ore is mined in open-pit or underground mines. The ore is then crushed and ground into a fine powder. The powder is then mixed with coke and limestone and heated in a blast furnace to produce molten iron. The molten iron is then poured into molds to form ingots. The ingots are then rolled into sheets or bars.<\/p>\n

Copper is a metal that is used in a variety of products, including electrical wiring, plumbing, and coins. Manganese is a metal that is used in a variety of products, including steel, batteries, and fertilizer. Chromite is a mineral that is used in a variety of products, including stainless steel, pigments, and refractories.<\/p>\n

Iron ore is the most important mineral for the production of steel. Steel is a strong and durable material that is used in a variety of products, including buildings, bridges, cars, and appliances.<\/p>\n","protected":false},"excerpt":{"rendered":"
