    摘要: A method for producing the direct reduced iron pellets. The method includes pelletizing, iron oxide-containing material, internal reductant and binder to form green pellets. The binder includes a non-combustible fibrous material. The method also includes firing the green pellets to convert the green pellets into direct reduced iron pellets.

    摘要: A magnetic ore purification system for enriching magnetic ore concentration in a feed material. The system includes an elutriator, an alternating current magnet, and an ultrasonic separator. The elutriator has a feed port for introducing the feed material into the elutriator and an enriched material port for collecting an enriched material having a magnetic ore concentration that is greater than the feed material. The alternating current magnet generates a uniform low strength magnetic field within the elutriator. The ultrasonic transducer introduces ultrasonic energy into the elutriator.
