A smelter is an industrial facility that processes metal ores to extract pure metals. This process involves heating the ore to high temperatures, which causes the metal to separate from impurities. Common metals produced in smelters include copper, aluminum, and zinc. Smelters play a crucial role in the mining industry, as they convert raw materials into usable metals for various applications. The extracted metals are then used in manufacturing, construction, and electronics, contributing to the economy and technological advancement. Environmental regulations are important for smelters to minimize pollution and manage waste effectively.
