Embodiment Construction
[0013] The method for reclaiming titano-magnetite in the mineral processing process of the present invention comprises the steps:
[0014] a. Classify the raw ore, the particle size of one type of raw ore is greater than 0.15mm, and the particle size of the other type of raw ore is less than 0.15mm;
[0015] b. Put the raw ore with a particle size larger than 0.15mm into the ball mill for fine grinding, so that the particle size of all the raw ore is less than 0.15mm;
[0016] c. Select titanomagnetite from all the raw ores with a particle size less than 0.15mm through a weak magnetic separation process, wherein the magnetic field strength of the weak magnetic separation process is 0.12T.
[0017] In step a, the raw ore includes vanadium-titanium-magnetite iron-dressing tailings, ilmenite iron-dressing tailings or both.
[0018] In order to improve the effect of particle size classification of raw ore, in step a, the raw ore is sorted through the cyclone and high-frequency fi...

Abstract
The invention relates to the technical field of beneficiation, in particular to a method for recycling titano-magnetite in the beneficiation process, which comprises the following steps: a, raw ores are classified, the particle size of one type of raw ores is greater than 0.15 mm, and the particle size of the other type of raw ores is less than 0.15 mm; b, the raw ore with the particle size largerthan 0.15 mm is added into a ball mill to be subjected to fine grinding treatment, and the particle size of all the raw ore is smaller than 0.15 mm; and c, all the raw ores with the particle size smaller than 0.15 mm are subjected to a low-intensity magnetic separation process, and titano-magnetite is separated out. The inventor obtains the product through a lot of practices and tests. Accordingto the method, high-quality titano-magnetite is separated from raw ores (vanadium titano-magnetite iron separation tailings and ilmenite iron separation tailings); the high-quality titano-magnetite isrecycled, the resource utilization rate is remarkably increased, the TFe grade of the raw ore can be controlled according to the requirement of the market for the quality of the titano-magnetite, therequirement for the TFe grade of the titano-magnetite is met, reasonable arrangement is conducted for recycling production, and the competitiveness of enterprises is improved.
Description
technical field [0001] The invention relates to the technical field of ore dressing, in particular to a method for recovering titanomagnetite in the ore dressing process. Background technique [0002] At present, in the beneficiation process, the vanadium-titanium magnetite is selected through a weak magnetic separation process to obtain the vanadium-titanium magnetite iron-separation tailings, and then the vanadium-titanium magnetite iron-separation tailings are subjected to strong magnetic separation. After the ilmenite is selected by the magnetic separation process, the ilmenite iron dressing tailings are obtained, and the ilmenite iron dressing tailings are treated as waste. Through the detection of vanadium-titanium-magnetite iron-dressing tailings and ilmenite iron-dressing tailings, both of them also contain some high-quality titano-magnetite, and the ilmenite iron-dressing tailings are directly treated as waste. The processing resulted in the waste of some high-qual...
