Coal mining
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is …

Extraction of Zinc: Process, Ores, Diagram
Roasting is the process of heating a sulfide ore to a very high temperature in the presence of air. This process is generally applied to sulfide minerals. The sulfide is converted to an oxide during roasting, and sulfur is released as sulfur dioxide, a gas. The sulfur dioxide obtained is used in the manufacture of sulphuric acid.

Aluminium
Recycling involves melting the scrap, a process that requires only 5% of the energy used to produce aluminium from ore, though a significant part (up to 15% of the input material) is lost as dross (ash-like oxide). An aluminium stack melter produces significantly less dross, with values reported below 1%.

Smelting
Smelting is a process of applying heat to ore, to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

Electrolysis
Electrolysis of Iron Ore. The current method of producing steel from iron ore is very carbon intensive, in part to the direct release of CO 2 in the blast furnace. A study of steel making in Germany found that producing 1 ton of steel emitted 2.1 tons of CO 2 e with 22% of that being direct emissions from the blast furnace.

How to Produce Steel Plates? The Steel Plates Manufacturing Process!
Steelmaking starts with melting the raw inputs of iron ore, coke (produced by carbonisation of coking coal) and limestone together in a blast furnace. The resulting red hot molten iron contains 4-4.5% carbon and other impurities that make it brittle. So we need to move to further process the steel to achieve the desired quality.
