What does metallurgy do

Metallurgy is a process and process of extracting metals or metal compounds from minerals and making them into metal materials with certain properties through various processing methods. It is not only an important part of engineering technology, but also an important driving force for the development of human civilization. ‌

The main purpose of metallurgy

Extract metals: Extract metal elements from ores, such as iron, copper, aluminum, etc. These metals usually exist in the earth's crust in the form of oxides, carbides and other compounds.

‌processing materials‌: The extracted metal is refined, alloyed, and processed into the required shapes and specifications to meet industrial and living needs.

‌Enhance performance‌: Improve the physical, chemical and mechanical properties of metallurgical processes to make them more suitable for specific purposes.

The main methods of metallurgy

‌Fire Metallurgy‌: Extracting metals or their compounds from ores using high temperatures, also known as dry metallurgy.
‌Hydrometallurgy‌: At room temperature or below 100°C, ore ore is treated with solvent to dissolve the metal in solution, and then metal is extracted by separation.
‌Electronic Metallurgy‌: Use electrical energy to extract, recover and refine metals from ores or other raw materials.

The history and development of metallurgy

Metallurgical technology has run through the history of human civilization from the Stone Age to the Bronze Age, and then to the large-scale development of modern steel smelting. With the application of physics and chemistry in metallurgy, metallurgy has gradually developed from traditional technology to a science, and has formed the professional discipline of metallurgical engineering.

Application fields of metallurgy

Metallurgy is widely used in ferrous metallurgy (such as steel production) and non-ferrous metallurgy (such as copper and aluminum production). It provides indispensable metal materials for the fields of industry, construction, transportation, electronics, etc.

In short, metallurgy is not only the basis for the production of metal materials, but also an important support for the development of modern industry.
