    Descriptions of the use of a flotation process have been found in ancient Greek and Persian literature suggesting its antiquity. During the late 19th century, the process basics were discovered through a slow evolutionary phase. During the first decade of the 20th century, a more rapid investigation of oils, froths, and agitation led to proven work-place applications, especially at Broken Hill, Australia, that brought the technological innovation known as “froth flotation.” During the early 20th century, it dramatically revoluti

  • COAL FLOTATION Mineral Processing & Metallurgy
    Coal Flotation with non-ionic SurfactantsExperimental Materials and MethodsResults and DiscussionSummary and ConclusionsIn coal flotation, the most commonly used collectors are oily materials collectors such as diesel oil and kerosene. For higher rank coals, the reagent consumption in flotation is low because of the high natural hydrophobicity of the coal. However, for low-rank coals (containing a greater amount of oxygen), flotation performance with these oily collectors is poor and large amount of collectors are required in order to obtain acceptable coal recovery.Polyethoxylated nonyl phenols constitute a m...

    Due to growth in surface mining and improved mining technology, the amount of coal produced by one miner in one hour has more than tripled since 1978. Surface mining is used to produce most of the coal in the U.S. because it is less expensive than underground mining. Surface mining can be used when the coal is buried less than 200 feet underground.
