(a) Name one ore from which iron is extracted. (b) One of the impurities in iron is removed in the form of calcium silicate. Write an equation for the reaction in which calcium silicate is produced. 11. (a) Name one ore from which copper metal is extracted. (b) The flow chart below shows a sequence of reactions starting with copper.

 — Originally, the iron was collected in pools called pigs, which is the origin of the name pig iron. Figure (PageIndex{1}): A Blast Furnace for Converting Iron Oxides to Iron Metal. (a) The furnace is charged with alternating layers of iron ore (largely Fe 2 O 3) and a mixture of coke (C) and limestone (CaCO 3). Blasting hot air into the ...

 — The design of a blast furnace is optimized to convert iron ore into iron effectively. Key components include: The Throat: This is the top section where raw materials (iron ore, coke, and limestone) are introduced. The Stack: Tall cylindrical structure where the raw materials descend by gravity.

 — Most ores also contain some other non-ore minerals (e.g., hematite) and some other sulphide minerals, especially pyrite (FeS 2). When ore is first processed (typically close to the mine) it is crushed to gravel-sized chunks and then ground to a fine powder and the ore minerals are physically separated from the rest of the rock to make a ...

 — The extracted ore undergoes processes such as crushing, grinding, and concentration to increase its iron content and optimize it for the subsequent stages of steelmaking. Once prepared, the concentrated …

 — The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.

 — Zinc can be extracted from its carbonate ore (calamine) through calcination. The steps are-1. Concentration of Ore. Calamine is converted into its oxide form by heating the ore strongly in the absence of air. This process is known as calcination and produces zinc oxide and carbon dioxide gas.

How is iron extracted from its ore? It's a long process which begins with Concentration through calcination roasting. Concentration removes the water and other volatile impurities such as sulphur and carbonates.

 — The reduction gases only dissolve oxygen from the iron ores. This causes the iron ores to crack on the surface. The appearance resembles a porous sponge, which is why the deoxidized and thus strongly ferrous iron ore is also called sponge iron.
