Waste rock disposal areas are usually located as close to the mine as possible to minimize haulage costs. If not properly managed, erosion of mineralized waste rock into surface drainages may lead to concentrations of metals in stream sediments. This situation can be potentially harmful, particularly if the metals are in a chemical form that allows them to be easily released from the sediments

method of slag disposal by dumping, which occupies land unproductively, sometimes causes water pollution, and can be seen as a waste of resources. Slags in history Smelting history goes back at least 6 000 years to the copper smelters of the Timna valley near Eilat in Israel. Copper is the world's oldest metal and was used more than 5 000 years ago for water plumbing in the Pyramid of Cheops

Reuse of mine wastes allows their beneficial application, whereas recycling extracts resource ingredients or converts wastes into valuable products. Yet, today, many of the proposed reuse and recycling concepts for mine wastes are not economic. Consequently, the great majority of mine wastes are still being placed into waste storage facilities. Significant research efforts are required to
Underground Disposal In 1975, the National Research Council conducted a study entitled Underground Disposal of Coal Mine Wastes, which evaluated the technical and economic feasibility of several underground disposal methods; namely, pneumatic backfilling, hydraulic backfilling, mechanical backfilling, hand packing, controlled flushing, blind flushing, and pneumatic flushing.
· Thus, ash and slag disposal areas of power plants are open systems within the fenced area. Hazardous constituents of ash can migrate from the ash dump surface through the air and water action contaminate the atmosphere, soil, groundwater and surface water in areas located a few kilometers from the waste accumulator.
Disposal Nonferrous slags are produced in a few locations, often remote from potential markets. As a result, nonferrous slags are not well utilized and most of the nonferrous slag produced is disposed of in slag dumps or stockpiles. MARKET SOURCES Nonferrous slags, when they are used, are marketed directly by the producers.
