Management of the Flow and Processing of Mining Waste Streams

Abstract

Technological advancements in mineral processing have increased the feasibility of refining low-grade ores. Because of this progression and continual depletion of high-grade ore deposits, much larger volumes of waste material are produced. At the same time, increasing environmental legislation and cost competitiveness dictate that these wastes be disposed of in a manner that is both environmentally acceptable and economically viable. To achieve these criteria, many mineral processing industries are dewatering waste streams in order to reduce the volume of tailings and increase water and reagent recovery. The subsequent dry disposal of these highly concentrated mineral tailings requires a tho..
