In fact, mining in Nigeria he said to have started with mining of tin ore in 1905. Though mining in Nigeria started in 1905, the industry only accounts for 0.3% of the nation's GDP. The domestic mining industry is underdeveloped, leading to the importation of some industrial minerals that the country has in abundance.

The process technology of the plant includes from extraction of gypsum to crushing, sifting, calcinations, grinding, mixing, testing and eventually packaging. The machinery and equipment required for mining will include wagons, drills with rod bits, compressors, loaders, bulldozers, rippers and trucks, etc.
FGD Gypsum Production Process. Mineralogically identical to natural gypsum, FGD gypsum, or synthetic gypsum, is produced from gas captured within emission control systems at coal fired electric utilities. An emission that would compromise air quality, sulfur dioxide (SO 2) gas, is the primary contribution coal makes to FGD gypsum.

This allowed gypsum from the Brightliing Mine to be taken to the processing plant at the Mountfield Mine. The cableway was subsequently replaced by a covered conveyour belt system. Today the mines are extensive and several times larger than the 6′ by 7′ tunnels of earlier years. Modern day miners travel underground by Land Rover.
FGD Gypsum Byproduct Processing. An unusual byproduct is generated at fossil-fueled power plants. Specifically, when flue-gas desulfurization (FGD) is used to remove sulfur dioxide from pollutants, FGD gypsum is formed. Ironically, this gypsum can be used for many commercial uses, including cement, drywall, glass manufacturing, and more.
