metallurgiatööstus

Metallurgiatööstus refers to the branch of industry concerned with the production of metals and their alloys. This complex sector involves several key stages, starting with mining and extraction of raw metallic ores from the earth. Once extracted, these ores undergo processing to concentrate the valuable metals, a step often involving crushing, grinding, and various separation techniques.

The concentrated ores are then smelted, typically in high-temperature furnaces, to separate the metal from its impurities. This process yields a crude metal that may require further refining. Refining processes, such as electrolysis or chemical treatments, are employed to achieve the desired purity and specific properties of the metal. Following refining, the metals are often cast into ingots or other shapes for further manufacturing.

The metallurgy industry is broadly divided into ferrous metallurgy, which deals with iron and its alloys (like steel), and non-ferrous metallurgy, which focuses on metals such as aluminum, copper, zinc, and precious metals. The end products of metallurgiatööstus are essential raw materials for a vast array of other industries, including construction, automotive, aerospace, electronics, and manufacturing. The efficiency and environmental impact of these processes are continuous areas of research and development.
