Question: identify four problem affecting the mining industry in nigeria

title: Mining industry of Nigeria
text: The mining of minerals in Nigeria accounts for only 0.3 % of its GDP , due to the influence of its vast oil resources . The domestic mining industry is underdeveloped , leading to Nigeria having to import minerals that it could produce domestically , such as salt or iron ore . Rights to ownership of mineral resources is held by the Federal government of Nigeria , which grants titles to organizations to explore , mine , and sell mineral resources . Organized mining began in 1903 when the Mineral Survey of the Northern Protectorates was created by the British colonial government . A year later , the Mineral Survey of the Southern Protectorates was founded . By the 1940s , Nigeria was a major producer of tin , columbite , and coal . The discovery of oil in 1956 hurt the mineral extraction industries , as government and industry both began to focus on this new resource . The Nigerian Civil War in the late 1960s led many expatriate mining experts to leave the country . Mining regulation is handled by the Ministry of Solid Minerals Development , which oversees the management of all mineral resources . Mining law is codified in the Federal Minerals and Mining Act of 1999 . Historically , Nigeria 's mining industry was monopolized by state - owned public corporations . This led to a decline in productivity in almost all mineral industries . The Obasanjo administration began a process of selling off government - owned corporations to private investors in 1999 .
