Metallurgical design aims to achieve a balance between these three objectives to ensure the efficient and sustainable production of metals.

Biometallurgy is not a traditional metallurgical process, as it involves the use of microorganisms to extract metals from ores.

Ore preparation involves crushing, grinding, and beneficiation to remove impurities and concentrate the metal content.

Pyrometallurgy utilizes high temperatures to extract metals from ores through processes such as smelting and roasting.

Hydrometallurgy is not a pyrometallurgical process, as it involves the use of aqueous solutions to extract metals from ores.

Hydrometallurgy utilizes aqueous solutions, chemical reactions, and sometimes electrolysis to extract metals from ores.

Pyrometallurgy is not a hydrometallurgical process, as it involves the use of high temperatures to extract metals from ores.

Electrometallurgy utilizes electrical energy to extract metals from ores through processes such as electrolysis and electrowinning.

Pyrometallurgy is not an electrometallurgical process, as it involves the use of high temperatures to extract metals from ores.

Casting is the process of pouring molten metal into a mold to create a solid object.

Hydrometallurgy is not a casting process, as it involves the use of aqueous solutions to extract metals from ores.

Rolling involves passing metal through rollers to reduce its thickness, increase its strength, and improve its surface finish.

Annealing involves heating metal to a specific temperature, holding it at that temperature for a period of time, and then cooling it slowly to relieve stresses and improve the metal's properties.

Hydrometallurgy is not an annealing process, as it involves the use of aqueous solutions to extract metals from ores.

Metallurgical design plays a vital role in ensuring the sustainable and responsible production of metals, while also contributing to technological advancements and reducing the environmental impact of metal production.
