Gangue refers to the waste material that is separated from the desired metal during the extraction process.

Limestone is added to form slag, which helps remove impurities during the extraction of iron.

Limestone is used as a flux in the extraction of iron to remove impurities as slag.

Bioleaching uses microorganisms to extract metals, resulting in less environmental impact compared to traditional methods.

Carbon acts as a reducing agent, providing electrons to reduce metal oxides to metals.

Flux is used to remove impurities from metal ores during the smelting process.

The blast furnace is primarily used to reduce iron ore into molten iron.

The primary role of a flux is to remove impurities from the metal during the extraction process.

Copper is a transition metal and can form complex ions due to its ability to coordinate with ligands.

Water is a common ligand that can form coordination compounds with transition metals.

A good reducing agent should have low ionization energy, allowing it to easily donate electrons.

Sublimation is not a method used for extracting metals; it is a phase transition from solid to gas.

Gold is often extracted using hydrometallurgy, particularly through cyanidation.

Gold is often extracted using hydrometallurgical methods such as cyanidation.
