Kenya Mining Africa
Minerals: Soda ash, fluorspar, and diatomite, gold, limestone, and niobium. Independence:12 December 1963 Area: 580,367 km2 Mining fact Kenya was not considered a particularly mineral-rich country until recent geological surveys revealed that the assumption might be wrong.This is yet to be fully explored. Kenya is an East African Soda ash Soda ash is the leading mineral export of Kenya. It is produced from a rock known as trona which is found in Lake Magadi area on the floor of the Rift Valley. Mining is done using dredging method. The mineral is scooped from the lake using a dredger and then transported to the factory where it is crushed to form soda ash.eLimu Resources and economic activities
