Which description applies to pure metals?

Pure metals are indeed mined and extracted through processes such as smelting, which involves heating the metal ores to separate the metal from impurities. This extraction is a fundamental aspect of metallurgy, where minerals containing metal are processed to obtain the pure form of the metal, such as iron, copper, or aluminum. During this process, ores undergo chemical changes that allow for the recovery of the pure metal, making them accessible for various applications in manufacturing and industry.

While some pure metals can be ductile and flexible, not all meet those criteria; for example, metals like tungsten are very brittle. Additionally, the statement that pure metals are always ductile and flexible does not universally apply. The notion that pure metals are mixed with other metals contrasts their definition, as pure metals are not alloys. Finally, the idea that pure metals are typically non-magnetic is also misleading, as many pure metals, such as iron, exhibit strong magnetic properties.
