  • Mine Waste Transfer and Disposal Methods Mine Tailings

    The main environmental impacts of mining waste include the loss of land following its conversion to a tailings pond or waste storage area and the introduction of acidic runoff or other contaminated sediments into the local environment. The specific environmental impact of waste depends heavily on the materials composition, type of ore mined

  • Tailings Wikipedia

    Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water

  • Tailingsfo What Are Tailings? Their nature and production

    The five basic types of reagent used in froth flotation recovery include collectors, frothers, depressants, activators and modifiers. When designing the processing plant, the types and quantities of reagents used should be considered together with any depressing requirements to lessen environmental impacts in the tailings streams (Ritcey 1989).
