ABSTRACT OF THE DISCLOSURE The invention relates to a method of processing ore of the type which includes the steps of grinding the ore, classification of the ore and concentration of the ore, the classification step following the step of grinding by preceding the step of concentration. According to the invention, the step of classification is of the type of a method wherein ore particles are generally simultaneously classified into fractions different from each other with respect to both size and density of the particles. The advance in the art is in that valuable, relatively heavy particles can be brought to the step of concentration in a relatively coarse state to thus reduce the cost of said step of grinding, whereby the efficiency and economy of the overall method is improved.
