Abstract: A method of manufacturing iron oxide coated sand using acid mine drainage and a method of treating heavy metal-containing water using the iron oxide coated sand are provided to economically reuse drainage containing contaminants and effectively remove arsenic presenting in contaminated water using the manufactured iron oxide coated sand. A method of manufacturing iron oxide coated sand using acid mine drainage comprises the steps of: obtaining the inorganic precipitant only after forming an inorganic precipitant by adding an alkali salt to acid mine drainage; mixing the inorganic precipitant with sand to prepare a slurry; heating the slurry at 60 to 550 deg.C for one hour to three days to coat sand with the inorganic precipitant; and removing the inorganic precipitant that has not been coated on sand, and washing and drying the iron oxide coated sand.
