prehistoric salt extraction

Prehistoric salt extraction involved early humans finding and collecting natural salt deposits, such as deposits left by evaporated saltwater lakes or salt-rich mineral deposits. They gathered salt by scraping or mining salt crusts from the surface or shallow underground layers. Sometimes, they used fire to heat and extract salt from salt-rich rocks or brine. Salt was crucial for preserving food and supporting health, making these techniques important for survival and community development. These methods were simple but effective, marking an important step in early human resource exploitation and technological ingenuity.
