摘要：This graphite tailings belongs to graphite schist deposits, the main mineral component is feldspar, quartz, diopside, amphibole, followed by mica, chlorite, calcite, pyrite, etc. The average particle sizes of the mineral is0.14 mm, -200 for the purpose of 13.84 %, dominated by short grain, viscous grain level is low, all tailings in condition of the 2.52 % increase water, bulk density is 1.7 g/cm(3). After experimental evidence, the direct use of graphite mine tailings, ordinary cement, foamer and other materials for prepared foam concrete, and its performance fully meet the requirements of B08 density rate in JC/T 1062-2007 standard and the middle strength for the A3.5.
