| Popis: | An earlier mathematical model, developed to describe oxidation of pyritic material in mine wastes and which assumed just one size for the particles composing the wastes, has been extended to take proper account of the range of particle sizes in the wastes. Comparison of the simpler model with the more realistic model shows that for practical purposes the simpler model is good enough to assess the magnitude and longevity of the environmental impact of pollutant generation in the wastes. It is, however, essential to include the particle size distribution to obtain accurate estimates of the heat source distribution profile and to a lesser extent the oxygen concentration profile, two parameters that can be measured and used to assess the applicability of the model to the real field situation. |
