Industrial Metallurgy

Explore the general properties and extraction of metals, including ore concentration, conversion to oxides, reduction, purification, and the occurrence, alloys, and uses of iron, copper, zinc, and aluminum.

Explore how metals occur in native and combined states, distinguish ores from gang impurities, and trace the metal extraction flow from crushing and concentration to metal production.

Explain how elements are extracted from ores, distinguishing native and oxide forms, using oxidation-reduction concepts and a standard sequence of crushing, grinding, concentration, and reduction to metals.

Explore ore concentration techniques in industrial metallurgy, including hydraulic washing and gravity separation, magnetic separation, and leaching to remove impurities and improve ore grade.

Convert concentrated ore to metallic oxide through roasting and calcination, remove impurities, and prepare the ore for reduction with preliminary treatments.

Explore the reduction processes in industrial metallurgy, from carbon and aluminium reductions in blast furnaces to electrolysis and hydrometallurgy, including fluxes, slag formation, roasting, and cyanide leaching.

Purify metal by oxidation, slag removal, and refining techniques, including electrolysis and zone refining, to remove impurities. Produce high-purity metals for semiconductors such as silicon and germanium by these methods.

Explore the occurrence, properties, extraction, and uses of iron, and examine iron-carbon alloys such as cast iron and various steels, including nickel, chromium, vanadium, and manganese alloys.

Explore how hematite iron ore is concentrated and reduced in a blast furnace to produce cast iron, using coke, limestone, and flux to form slag.

Explore the occurrence, properties, and alloys of copper, including brass, bronze, and German silver, and learn its uses from electrical cables to ornaments and religious artifacts.

Explore the copper extraction process from ore to metal, covering roasting and reduction, smelting with fluxes to form blister copper, and refining by electrolysis to pure copper.

Learn how zinc is extracted from native or combined ores through roasting and electrolysis, and its uses in galvanization and alloys like brass and bronze.

Learn the two-stage extraction of aluminium from bauxite: digestion with sodium hydroxide to yield alumina, then Hall-Héroult electrolysis to produce aluminium, its uses, and key process details.

Examine commercial forms of iron—cast iron, steel, and wrought iron—covering carbon content, impurities, and properties, and explain conversion from cast iron to wrought iron and steel.
