Traditional Ways of Knowing: Salt Harvesting | manoa ...
Traditionally, salt was harvested from either solar evaporation ponds or rock deposits. Salt evaporation ponds are shallow, artificial basins designed to extract salt from seawater, salty lakes, or mineral-rich springs through natural evaporation (SF Fig. 2.4). As the water dries up, the salt crystals are harvested by raking.

Absorber coatings have to withstand operating temperatures around 400°C for thermal oil plants and above 550°C for direct steam or solar salt plants. An accelerated test to check whether a coating can withstand extended times at these temperatures is to overheat the coating, e.g. [86 ].
How to Make Salt by Solar Evaporation
The manufacture of salt by solar evaporation began in the vicinity of Syracuse, Onondaga county, in 1789. A natural brine 68° to 80° salometer, with 17 to 20 per cent, sodium chloride, was and is still used. The brine is stored in glacial gravels and was evidently formed by the circulation of ground waters, through adjacent beds of rock salt.

Cargill Salt Group's Salt Manufacturing Processes | Cargill
Solar Salt Production is the process in which naturally occurring salt water (from a sea, lake, etc.), is channeled into a series of shallow, interlocking ponds. Over time, the water moves through the sequence of ponds that allow evaporation of water to create brine solutions until the most saturated brines evaporate to form salt crystals.
