Transfer of Ore and Major Components in Reduced Fluid: An Experimental Study

摘要

Problems associated with the possible transfer of major and ore components in anhydrous reduced fluid systems have consistently been discussed in the scientific literature. However, there have so far been no systematic experimental studies conducted in this field, with the exception of certain sporadic works (e.g.,). Various mechanisms of carbon precipitation from fluid are suggested in [6]. The possibility of the simultaneous transfer of major and ore components is suggested in [7-9]. In order to elucidate the ability of reduced fluids to both extract major and ore components from an alu-minosilicate matrix and provide their transfer and deposition by migration through a rather compact fine-porous rock, we carried out two series of isothermal experiments: (1) an aluminosilicate matrix (granitic glass) is combined with a carbonate cone, through which a reduced fluid migrates (pressure gradient at inlet and outlet reaches 1000 bar in the reduced carbon-bearing fluid); (2) the same model in the water-hydrogen fluid. The runs lasted 48-72 h.
