  • Graphite flotation

    The flotation rate depends on the size of the spherolites, the flotation distance on the travel speed and the time available for flotation, and time in turn is a function of wall thickness. In thick-walled castings made of hypereutectic nodular graphite cast iron large spherolites are formed which have plenty of time for flotation due to the long solidification periods.

  • Enhancement of flaky graphite cleaning by ultrasonic

    The flotation tests on graphite verified that the yield, carbon content and recovery of concentrates obtained through ultrasonic treatment flotation were much greater than those attained using conventional flotation. The carbon content of the flotation concentrates products reached 95% after only one flotation step under ultrasonic-assisted flotation. This revealed that, after ultrasonic

  • BENEFICIATION OF LOW GRADE GRAPHITE ORE OF EASTERN

    In froth flotation, graphite ores are often subjected to a suitable hydrocarbon oil treatment to alter their hydrophobicity, enhance recovery, and /or improve selectivity [13]. Conventionally, the collector used in most of the flotation circuit is diesel oil in combination with pine oil as frother. The dosage of collector and frother has significant effect on flotation performance [14]. The

    Graphite used for high tech products such as Lithium ion batteries or fuel cells demands higher purity than typically upgraded by flotation. The chemical purification technology should be considered for further purification of graphite concentrate to TGC 99.99%. A basic process is thermal treatment in the presence of caustic reagents to dissolve siliceous impurities such as quartz, feldspar or

  • Froth flotation Wikipedia

    Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the
