Salt extraction methods have evolved over time from "summary" of Salt by Mark Kurlansky

Throughout history, the process of extracting salt from various sources has undergone a series of transformations. In ancient times, salt was primarily obtained through evaporation, a method that required large bodies of water and extensive periods of time. The earliest salt works were established along the shores of these bodies of water, where the sun and wind played crucial roles in the evaporation process. As civilizations progressed, so did the methods of salt extraction. The invention of the salt pan revolutionized the industry by allowing for more controlled evaporation in smaller, man-made ponds. This innovation increased efficiency and productivity, making salt more accessible to a larger population. Over time, new technologies such as vacuum evaporation and salt mining further refined the extraction process, enabling salt to be produced on a massive scale. The discovery of sa...
