Extraction Of Iron Amp Concentration Of Ore An Overview

Sep 23, 2019 The extraction of iron from its ore is the third and the penultimate process in metallurgy, which is the process of separating metals from their ores. The common ores of iron are iron oxides. These oxides can be reduced to iron by heating them with carbon in the form of coke. Heating coal in the absence of air produces coke.

Processes Extraction Mining Smelting Refining

Mining The ore is removed from the ground in either open pit or underground mines. Underground sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore. Open-pit 90 of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers. The ore

Processes And Procedures In The Extraction Of Iron

Feb 15, 2021 The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce ironIII oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.
