Zinc In Sludge From Spanish Reservoir Break Equals Mine's Annual Output, Researchers Find
...rs suggested. Mined ore is ground and the useful zinc is separated from rock byfloating the pulverized ore in a reservoir. Once the metal is removed from thepool's surface, what is left is a reservoir filled with highly acidic water andmining residue, often containing toxic minerals that failed to......for energy production, the cleanproduction of many useful chemicals and the biodegradation of pollutants inground water can all be improved by advances in the controlled catalyticoxidation of organic compounds, Stair said.
