itp mining: energy and environmental profile of the u.s,to keep mining practices from permanently destroying wildlife habitat, all states including florida, where most phosphate rock is mined, require the reclamation of mining areas. the two stages of reclamation are contouring and revegetation. contouring is the stage in which the mined land is reshaped to resemble pre-mining topography and drainage..simplified modeling of phosphorus removal by vegetative,mining sand tailings in central florida, which still contain apatite (phosphate rock), have shaped the landscape in reclaimed lands at the upper peace river basin. the objective of this study is to model the efficiency of vegetative filter strips for controlling surface runoff pollution from phosphate mining.environmental impact of phosphate mining and beneficiation,although the subject of mining and its environmental impacts are very wide to be covered in this review, concerns about the impact of phosphate mining and processing typically emphasis on its potential effects on water pollution, air pollution, and human health were accessed. we reviewed published information at different stages of mining; current mines, closed old mines and reclaimed mines.
