It is believed that the pink color of micro-organisms are responsible, and a high concentration of minerals in the surrounding soils, mainly chlorine and minerals.
Lake Retba like its counterpart in Australia, the lake is very salty Hillier and separated from the ocean only a narrow strip of dunes a few hundred meters. This is due to the fact that in ancient times the lake was small coves, which, by the applied sand was cut off from the open water area. As a result of evaporating seawater, seawater salinity growth followed, until the present level, which in the lake Retba is 38%, or about the same as the salinity of the Dead Sea.
The lake is still African mined salt, and the manner of delivery has not changed for years and is passed down from generation to generation. The whole process starts from the bottom grab the Pink Lake salty sludge. It is then transported to the shore, where salt is washed and dried in the sun. After drying, the salt forms a dense shell, which must be crushed. Finally ready to sell salt Piles left behind in small mounds.
