As a previous blog, Mining and the Environment: What Happens When A Mine Closes? explains, tailings—mineral waste products—are a major pollutant. Tailings may be dumped in or near water or transported by wind or water to contaminate the surrounding area. Mine sites typically manage tailings by constructing ponds secured by dams.
May 28, 2014· Mine tailings are a source of metal exposures in many rural communities. Multiple air samples are necessary to assess the extent of exposures and factors contributing to these exposures. However, air sampling equipment is costly and requires trained personnel to obtain measurements, limiting the number of samples that can be collected.
Now you have seen the list of solid minerals in Nigeria and their states of location. Now I will discuss the major solid minerals starting with coal. Coal was first discovered in 1909 in the South Eastern state of Enugu in Nigeria and it’s exploration began at Ogbete Mine in 1916.

Besides molybdenum, Armenia
Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.
