Each year the mining industry generates tremendous quantities of solid wastes as a byproduct of the mining and concentration or preparation of valuable ores minerals and coal In addition the quantities of these wastes generated on a yearly basis is increasing due to increased production resulting from rising demand the depletion of near surface high grade ores which makes necessary the
Unfortunately in cases where iron has contaminated large aquifers or when alternative water sources are too far away bypassing the problem is not possible Removing iron by oxidation and filtration In cases of iron levels higher than ppm sequestration is not possible and therefore the iron must be physically removed from the water

Since mining operations ceased the mine partially filled with water This water becomes contaminated as acid mine drainage that drains into Railroad Creek at concentrations toxic to aquatic life The hazardous substances at the site include iron and aluminum compounds arsenic cadmium copper zinc and lead Contamination from the mining
Mining uses water primarily for mineral processing dust suppression slurry transport and employees needs In most mining operations water is sought from groundwater streams rivers and lakes or through commercial water service suppliers But often mine sites are located in areas where water is already scarce and understandably local communities and authorities often oppose mines using
The washed material passes through the run out hopper onto the variable speed discharge conveyor and is sent to a washing screen where the disagglomerated contamination is rinsed off The iron ore process route For this theoretical scenario a medium grade hematite deposit with an average quality of approximately 58 per cent Fe has been chosen
