NOVELTY - System comprises: a fluid containing a population of suspended coal fines; an activator polymer added to the fluid to complex with the suspended coal fines to form activated coal fines; and an anchor particle complexed with a tethering agent to form tether-bearing anchor particles, where the tether-bearing anchor particles are capable of complexing with the activated coal fines to form complexes removable from the fluid, and the complexes removable from the fluid comprise a composite material comprising complexed coal fines and anchor particles.    USE - The system is useful for removing coal fines from a fluid (claimed), and forming a coal-on-coal composite particle and combustible coal pellets.    ADVANTAGE - The system and method provide combustible pellets that optimize combustion efficiency; and provide for disposal of both coal fines waste and biomass waste in a combustible pelletized product.    DETAILED DESCRIPTION - System, comprises: a fluid containing a population of suspended coal fines; an activator polymer added to the fluid to complex with the suspended coal fines to form activated coal fines; and an anchor particle complexed with a tethering agent to form tether-bearing anchor particles, where the activated coal fines residing within the fluid volume, the tether-bearing anchor particles are mixed with the fluid volume to contact the activated coal fines, the tether-bearing anchor particles are capable of complexing with the activated coal fines to form complexes removable from the fluid, and the complexes removable from the fluid comprise a composite material comprising complexed coal fines and anchor particles. INDEPENDENT CLAIMS are included for:    (1) removing coal fines from a fluid, comprising providing an activator polymer capable of interacting with a population of coal fines suspended in a fluid, adding the activator polymer to the population to form activated coal fines, providing an anchor particle, complexing the anchor particle with a tethering agent capable of complexing with the activated coal fines, thus forming tether-bearing anchor particles, mixing the tether-bearing anchor particles with the activated coal fines to form a complex removable from the fluid, where the complex comprises a composite material comprising coal fines and anchor particles and removing the composite material from the fluid; and    (2) an energy-bearing pellet comprising either a product produced by the method as above per se, or a composite material comprising activated coal fines complexed to combustible tether-bearing anchor particles, or a composite material comprising an energy-containing fine material and a combustible anchor particle in a complex, the complex further comprising an interacting pair of polyelectrolyte, where the first of the pair of polyelectrolytes is bound to the energy containing fine material and the second of the pair of polyelectrolytes is bound to the combustible anchor particle.
