Abstract

Mineral process simulation technology is consolidating more and more in the day by day of mineral process engineers, operation and planners, for the diagnosis of circuits, plants projects, equipment sizing, material balances, sensibility analysis and risk of iron ore treatment plants. The stationary simulation of mineral process can easily generated flowsheets with coherent and realistic mass balances through phenomenological mathematical models that represent the performances of the several existent unitary stages in an iron ore treatment plant. Using more complex mathematical models it is possible through retro-calculation to size the equipments and to estimate the investment cost. Using the static simulation it is possible to vary flowsheets and characteristics of the ore that feeds the plant accomplishing with extreme agility a sensibility analysis and risk for several flowsheets options. The dynamic simulation performed with a specialist system and mathematical models to represent the varies unitary options, enables to analyze the performance of the plant for a lifetime of the mine in a short space of time, obtaining precisely the global recoveries, the production of reject, etc.
