The trading and transporting of salt, Tombouctou, Mali

"Salt from most sources in Africa requires preparation before it can be used or traded. Almost all the salt used by ordinary people in the last five centuries was obtained from local sources. Only the few, particularly rich sources were more intensively exploited and the product traded over distances of up to 1,000kilometers. The most famous deposits are in the deserts of Mauritania and Mali. After the destruction of Taghaza site (Mali), Taodeni (Mali) took its place and in 1975 was still producing several thousand tons of salt a year. From 16 square kilometers of salt pans, laborers, mainly convicts, mined the salt in 60-kilogram slabs from shallow trenches. Caravans still exported the slabs to Tombouctou."
