    As a result of magnetic separation, magnetite is recovered into the tailings (Figures Figures4 4 and and5). 5). Along with closed intergrowths of magnetite, open intergrowths are visualized in the hematite matrix, which, upon magnetic separation, will precipitate into magnetite concentrates, which will lead to a decrease in the iron content in it.

    If coal were first converted into a clean gas (free of particulates) before it was burned in an MHD unit, the same problems would have to be overcome as when natural gas is the fuel. If coal were to be used directly as the fuel for MHD generation, all of these already difficult problems would be compounded.

  • Recycling - Wikipedia

    Recycling is the process of converting waste materials into new materials and objects. The recovery of energy from waste materials is often included in this concept. The recyclability of a material depends on its ability to reacquire the properties it had in its original state. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions.
