Treatment of Acid Mine Drainage by the High Density Sludge …
As described by Kuit, based on considerable pilot-plant work, a plant had been successfully designed to treat AMD, and the process produced sludge that was substantially denser than that achieved with simple neutralization. At that time, the plant had been operating for only 1 year, but the quality of effluents produced met or fell under the limits
