How Coal Works | Union of Concerned Scientists

Two dominant methods account for the vast majority of underground coal mining: "room and pillar" and "longwall" mining.. In room and pillar mining, seams of coal are partially mined, leaving large pillars of coal intact to support the overlying layers of rock. When finished, miners practice "retreat" mining, extracting as much coal as possible …

Extraction of Iron: Meaning, Purification, & Extraction Methods

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.
