Extraction of Iron Metallurgy Blast Furnace and Reactions
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. This concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.

How Limestone Is Extracted at Vetter Stone
2020.2.25 The actual extraction of limestone is made by separating the rock in quarry ledges and dividing it into blocks. Here is an overview of Vetter’s Stones extraction process: On one exposed side, a 50-foot horizontal hole is drilled at the base of the ledge where limestone will be extracted. Another 50-foot hole is drilled every eight to ten feet.
