The invention discloses a method for high-value utilization of ordinary high-silicon iron ore concentrate, and relates to the technical field of ore dressing. The method for high-value utilization of ordinary high-silicon iron ore concentrate includes the following steps: S1, collect ordinary iron ore, and add it to a ball mill for ball milling operation; S2, add the iron ore obtained in step S1 to a tower mill Inside the tower mill operation. The high-value utilization method of ordinary high-silicon iron concentrate adopts the technological process of ball mill, tower mill combined grinding, coarse and fine classification, combined magnetic separation of drum magnetic separator and electromagnetic elutriation machine, and cationic reverse flotation desiliconization. Three products of super iron concentrate, high-grade iron concentrate and high-silicon building material raw materials are produced, with strong process adaptability, good sorting effect, low production energy consumption, no tail emissions, and can be used for large-scale industrial production of ordinary The method of high-value utilization of high-silicon iron concentrate solves the problems of low added value of ordinary iron concentrate products, high energy consumption and poor indicators of super iron concentrate production.

The invention discloses a combined beneficiation method for treating micro-fine grain disseminated iron ores. The combined beneficiation method comprises the following steps of (a) performing first-stage grinding and classification on the iron cores to obtain overflow ore pulp and classification sand setting ores and returning the classification sand setting ores to first-stage grinding and classification; (b) performing low-intensity magnetic separation on the overflow ore pulp obtained in the step (a) to obtain iron ore concentrate and low-intensity magnetic separation tailings; (c) performing strong magnetic separation on the low-intensity magnetic separation tailings to obtain first-stage high-intensity magnetic separation concentrate and high-intensity magnetic separation tailings; (d) performing second-stage grinding and classification on the first-stage high-intensity magnetic separation concentrate obtained in the step (c) to obtain overflow ore pulp and classification sand setting ores and returning the classification sand setting ores to second-stage grinding and classification; (e) performing strong magnetic separation on the overflow ore pulp obtained from the step (d) to obtain second-stage high-intensity magnetic separation concentrate and high-intensity magnetic separation tailings; and (f) performing separation on the second-stage high-intensity magnetic separation concentrate obtained in the step (e) by using a positive flotation technology to obtain flotation concentrate and flotation tailings. The micro-fine grain red iron ores are subjected to separation by the combined beneficiation method, the iron operation recycling rate is above 85%, and the iron grade of total concentrate is above 64%.
