Mass transfer can be thought of as an additional rate process, which in combination with reaction kinetics, determines the rate of substrate consumption. Fig. 1 depicts the influence of the relative rates of diffusion, convection, and reaction on the substrate consumption by a binding reaction that follows Langmuir kinetics on the lower boundary.

For example, assume that raw ore is a two component system comprised of a valued mineral and host rock having relative densities of 6.30 and 2.65, respectively. The amount of valued mineral is 30% of the total ore.Total Solid Mass, M: Mineral + Host Rock – 30 + 70 = 100 Total Volume, Vs: Total Solid Relative Density

Fluid-aided mass transfer and subsequent mineral re-equilibration are the two defining features of metasomatism in silicate rocks and must be present in order for metamorphism to occur. Taking into account geological time scales, the amount of fluid required need not be great (considerably less than 0.01% of the total volume of the rock) …
