obtained from the mine is of high grade, it is shipped as such to the fertilizer industry. It is however often poor in quality containing 15-20% P 2 O 5 and a number of impurities. Such ores are upgraded by beneficiation process. Beneficiation is a process of ore dressing in order to remove impurities and thereby to improve the grade of the ore.

Mining for production occurred by 1850 following the discovery of similar deposits in southeastern Tennessee in 1843 (Sweet and others, 1989; Magee, 1968). The Toncray mine in Floyd County was opened initially on a pyrrhotite vein that also contained chalcopyrite and large amounts of the supergene mineral chalcocite (Watson, 1907).
