The invention discloses a mineral processing method of comprehensively recovering gold-iron oxidized minerals in a grouping and classifying manner. The mineral processing method comprises the following steps of grinding raw minerals, conditioning pulp with water, carrying out low intensity magnetic separation to obtain low-intensity magnetic separation concentrates and low-intensity magnetic separation tailings, carrying out high intensity magnetic separation on the low-intensity magnetic separation tailings to obtain high-intensity magnetic separation concentrates and non-magnetic products, then adding the low-intensity magnetic separation concentrates, the high-intensity magnetic separation concentrates and the non-magnetic products into a mixture respectively, and carrying out cyanide leaching to finally obtain magnetite concentrates, brown iron concentrates and golden liquid. According to the mineral processing method, the recovery rate is high, and the cost is low; the iron grade of the obtained magnetite concentrates is 60-63.21 percent, and the iron recovery rate is 30-33 percent; the iron grade of the brown iron concentrates is 50-52 percent, and the iron recovery rate is 55-58 percent; the gold recovery rate of the golden liquid is 90-92 percent; and the mineral processing method is suitable for comprehensively recovering valuable elements in the gold-iron oxidized minerals and has important popularization and application values.
