• the physical properties of coal gangue

    the utilization of coal gangue is strictly limited. A few field projects that used coal gangue have not been reported. Because the property, composition, and quality of coal gangue are related to factors such as the coal’s location, process methods, and outer conditions, it is difficult to keep the chemical and physical properties of coal gangue

  • Separating coal and gangue using three-dimensional laser

    10-12-2017· Physical relationships of objects to be measured, as well as laser and measuring data planes are also presented, depending on principles of 3D laser scanning. A parameter selection method is presented to determine the appropriate photoelectric recognition dev to use for coal or gangue, while error due to voids between objects was measured, and transportation belts analyzed.

  • Study on the Parameter Optimization and Strength

    The results determined 7.5% as the optimum amount of emulsified asphalt in coal gangue emulsified asphalt mixture and recommended the best parameter combination of 7.5% emulsified asphalt, 6% coal gangue, and 5% water consumption.

  • Gangue Wikipedia

    In mining, gangue (/ ɡ æ ŋ /) is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. It is thus distinct from overburden,which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed, and from tailings,which is rock already stripped of valuable minerals.

  • Mineral processing Wikipedia

    There are a number of ways to increase the concentration of the wanted minerals: in any particular case, the method chosen will depend on the relative physical and surface chemical properties of the mineral and the gangue. Concentration is defined as the number of moles of a solute in a volume of the solution.

  • Gangue Mineral an overview ScienceDirect Topics

    The key gangue components in the ferrous materials include SiO 2, Al 2 O 3, CaO, MgO, S, and P along with trace elements like Mn, Cu, Na, K, and Zn in the form of complex oxides. The majority of these components are fluxed into the molten slag.

  • Mechanical and Acoustic Emission Behavior of Gangue

    The differences in AE behavior between gangue concrete and ordinary concrete were also analyzed. The mechanical test result shows that the compressive strength of gangue concrete can reach 35–40 MPa. Comparing with ordinary concrete, gangue concrete has larger initial porosity and abrupt rupture.

  • Mechanical and Acoustic Emission Behavior of Gangue

    The application of gangue concrete can be an effective method to solve the massive gangue heap and shortage of raw materials of concrete by replacing the gravel and river sand with crushed gangue. An Acoustic emission (AE) is one of the non-destructive testing methods that can be used for damage detection of the gangue concrete structure.

  • Separating coal and gangue using three-dimensional laser

    10-12-2017· In this , the physical properties of coal and gangue are compared and a separation method based on three-dimensional (3D) laser scanning is presented. The method presented here is based on measuring the volume of an object using 3D laser scanning, determining its weight via weigh-in-motion technology, and then calculating density.

    Emulsified asphalt mixture has the characteristics of convenient construction and durable performance, but its poor early strength and demulsification seriously restrict the popularization and application of this material. At present, the coal gangue produced by coal-fired power plants is generally discarded, resulting in serious environmental pollution.
