Smelting Of Metal Ores

Smelting - Wikipedia

Smelting is a process of applying heat to ore in order 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. The reducing agent is commonly a source of carbon, such as coke—or, in earlier times, charcoal.

smelting | Definition & Facts | Britannica

The first metal to be smelted in the ancient Middle East was probably copper (by 5000 bce), followed by tin, lead, and silver. To achieve the high temperatures required for smelting, furnaces with forced-air draft were developed; for iron, temperatures even higher were required. Smelting thus represented a major technological achievement.

Hand tool - Smelting | Britannica

Hand tool - Hand tool - Smelting: Perhaps 1,000 years after humans learned about melting virgin copper, they found that still another stone, a brittle one directly useless for tools, would produce liquid copper if sufficiently heated while in contact with charcoal. This step was epoch making, for it was the discovery of smelting, or the separation of a metal from a chemical compound called ore.

Smelting - Simple English Wikipedia, the free encyclopedia

Smelting is the general term for getting a metal from its natural ore.Gold is an exception because it is usually found as a pure metal. Other metals, like iron, copper, zinc, and silver, need to be got from their ore.. The process of smelting always involves heating the ore, and may also use a reducing agent like coke or charcoal.Most ores are oxides, sulfides or carbonates.

Impacts of Smelting - Base Metal Smelting

Smelting is known to be a major cause of pollution in the environment. When smelting occurs, along with the metal produced, a solid waste product, called stag, is also produced [1]. This slag is emitted into the air and can be a cause of the pollution although not a major one. The majority of the pollution is caused by air emissions [1].
