 Minning Industry



Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, lode, vein, seam, reef or placer deposit. These deposits form a mineralized package that is of economic interest to the miner.

History of mining in Nigeria

Before the discovery of oil and the consequent decline in mining, Nigeria was a hub of mining activities, dating back to 1902 with the first mining of tin ore by the Royal Niger Company in 1905. Gold was mined subsequently in the present Kogi and Niger States in 1914 and coal in present day Enugu State in 1916. 

Mining contributed to the development of a functional railway industry helping to transport mined coal from Enugu to the seaport in Port Harcourt and to a power plant in Oji River. “With tin ore mining and processing  came the establishment of the largest smelter in Africa (Makeri smelter in 1961) as well as a power plant in Jos. Finally, the establishment of industrial complexes and behemoths (at the time) of manufacturing came with iron ore, including the Ajaokuta Steel Mill, with the capacity to produce 5.7 million tonnes of liquid steel; Delta Steel plant with a capacity of 2 million tonnes of steel products; and three inland mills in Osogbo, Jos and Katsina,” the report added.


Advantages of Mining include but not limited to the following:

-          mining serves as the primary source income at different levels of economic growth

-          mining is the source of employment for both high and low class citizens

-          90% of raw materials used in manufacturing industries are gotten from mining activities e.g coal, crude oil, limestone e.t.c

One of  the major disadvantages of Mining on the other hand is that mining adversely affects  the environment in numerous ways, which include:

-          soil erosion which eventually result to wearing way of the top soil for agricultural purposes.

-          oil spillage in areas where oil mining is taking place like the Niger Delta, result to water pollution in the nearby water bodies and at the same time reducing soil fertility thus, greatly affecting farming in those areas.

-          smoke given out during processing of minerals contain carbon monoxide (co) ,which is gotten as a result of incomplete combustion, carbon monoxide is one of the greenhouse gases that when release into the atmosphere react with other natural gases and eventually cause ozone depletion and global warming.

What do you think, should we overlook the disadvantages of mining given that it greatly contribute to the economy, or new mining processes with less impact should be adopted?
