Salt: Separating Mixtures

The video explains the extraction of pure table salt from natural sources like salt flats and rock salt mines. In Utah, salt flats formed from evaporated lakes are a major source of salt. The process involves pumping water into ponds, allowing evaporation, and collecting crystallized salt. Similarly, rock salt is mined, separated from clay, and purified. These processes are scaled up industrially to produce salt for consumption.

Explain the process of separating salt from clay in a salt mine.

What is the final step in obtaining pure salt from the salt solution?
