  A novel dry beneficiation process for coal: International …

  20191118 · More than two-thirds of coal in China is present in dry areas and cannot be separated by traditional wet coal preparation techniques. Dry coal beneficiation is an effective technique to realize coal separation and upgradation, as it does not consume water, has a low cost and is pollution-free. In this study, an air dense medium fluidized bed …

  Separation of methane from low concentration coal bed ...

  2019123 · Abstract Abstract: A method of separating and concentrating CH4 from coal bed methane (CBM) by hydrate formation was proposed. The separation experiments of CBM simulation gas (13.11vol% CH4+86.89vol% N2) were carried out by adding promoter solution of 5.8mol% Tetrahydrofuran (THF)?0.03mol% Sodium dodecyl sulfate (SDS). …

  Gravity Separation | SpringerLink

  2022228 · Gravity separation is a method in which materials/minerals are separated based upon the difference in particles density [ 1 ]. Water as a medium is an important factor in improving the differential movement between various particles during gravity separation and eventually sorting different particles [ 2 ]. When water is removed, and air plays ...
