Purification Process Of Limestone

How iron is made - material, manufacture, making, history .

The process of extracting iron from ore produces great quantities of poisonous and corrosive gases. In practice, these gases are scrubbed and recycled. Inevitably, however, some small amounts of toxic gases escape to the atmosphere. A byproduct of iron purification is slag, which is produced in huge amounts.

Limestone - Wikipedia

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.
