Dry ore beneficiation is an alternative approach to wet processing aimed at minimizing the energy expense. Ore fines fed onto a separator plate and subjected to a controlled blast of air issuing from its base can be separated based on their density values in proportion to their iron content. Particle-tracking simulations were carried out to characterize the ore separation degree as a function of various parameters, namely blast velocity, particle size, rate of iron ore feed and separator plate orientation. The economics of this process are assessed based on the optimal parameters.
