  • A review of stateoftheart processing operations in coal preparation

    While the fundamental goal of coal preparation is to improve the value of the raw material, the physical removal of waste material supports several complementary objectives. First, coal users often demand a specific particle size which supports downstream uses. Since the size of runofmine coal can vary widely, the size

    During the process of coal change, chemical reactions occur on the reactant surfaces and coal solid surfaces. Most of the surfaces are related to the pore structure, i.e., the diffusion of products and penetration of reaction media are related to the coal pore structure in most cases. The porosity also affects the physical and
