Method for strengthening pelletizing property of superfine magnetite concentrates

The invention discloses a method for strengthening the pelletizing property of superfine magnetite concentrates. The method comprises the following steps that after the superfine magnetite concentrates are dried, the partially dried superfine magnetite concentrates are uniformly mixed with an organic-inorganic composite binder for the first time, and a lime aqueous solution containing ferrite is sprayed into the mixed material in the primary uniform mixing process to adjust the moisture so as to obtain a primary mixed material; and then the remaining dried superfine magnetite concentrates are uniformly mixed with the primary mixed material for the second time, water is sprayed into the mixed material in the secondary mixing process to conduct adjusting to reach the pelletizing moisture, a secondary mixed material is obtained, and pelletizing is conducted on the secondary mixed material through a disc pelletizer. The method is easy to operate, low in production cost and environmentally friendly, the pelletizin
