Environment in the mining area is being affected mainly due to deforestation, land loss due to lease area and pollutants discharged from mines to the nearby agricultural land and forests. In most cases, sal forests are being affected due to mining. Forest areas are being degraded due to construction of roads, settlements and mines expansion.

It was associated with goethite and an array of phosphate minerals (Chamberlain, 1877, Hawley and Beavens, 1934; U.S.G.S., 1976; Paull, 1977). It was mined along Iron Ridge near Mayville in Sec. 12 and 13 T.11N R.16E until the mid-1970's. Beds up to 55 feet thick occurred.
