Problems solved by technology

[0003] 1. Combined re-election-flotation process: This process is difficult to control the fluctuation of the ilmenite grade entering the flotation operation, and the amount of ore is not stable, the operation is difficult for workers, and the recovery rate of ilmenite metal is generally low. The metal recovery rate of iron tailings is generally only 12-14%

Example Embodiment

[0019] See figure 1 , The process of the new method for ilmenite separation of the present invention is:

[0020] 1. Use the tailings of vanadium-titanium magnetite iron as raw materials (TFe10~13%, βTiO 2 11~13%), after a section of strong magnetic (Slonφ1750), the magnetic field strength is 1300A, after throwing the tail, titanium βTiO can be obtained 2 17~19% crude titanium concentrate;

[0021] 2. The crude titanium ore is subjected to a closed-circuit grinding process (1 φ2721 lattice ball mill and 2 high-frequency fine screens). The qualified products are scanned through weak magnetic field and enter the second section of strong magnetic (Slonφ1750). The magnetic field strength is 750A. Obtain βTiO 2 22~24% titanium concentrate;

[0022] 3. After the reverse flotation desulfurization operation (the main reagent is xanthate), the tailings of the desulfurization operation enter the full-size floating titanium operation, and the main reagent is R-2 (produced by Sichuan Chengdu ...

Abstract

The invention discloses a titaniciron ore floatation method at full grades, which uses the tail mineral after the selection of V-Ti-bearing iron ore as raw material, and after a strong magnetic throwing at the magnetic field intensity of 1300 A to attain the ª‰TiO2 rubble titanium finished ore of 17-19%; then milling the rubble titanium ore in closed circuit, the acceptable product can via the weak magnetic iron selection enter the two-stage strong magnetic field in the magnetic field intensity of 750 A, to attain the ª‰TiO2 titanium finished ore of 22-24%; at last processes the reverse-floatation and desulfurization, the tail mineral can enter the floatation process at full grade, while the metal recovery rate can reach 34-36%. The invention has short process, lower cost, higher metal recovery rate, controllable production, and excellent economic benefits.

Description

technical field [0001] The invention relates to a production process for recovering ilmenite from vanadium-titanium-magnetite iron dressing tailings, in particular to a full-grain grade ilmenite flotation method. Background technique [0002] In the prior art, the beneficiation of ilmenite mainly contains the following methods: [0003] 1. Combined re-election-flotation process: This process is difficult to control the fluctuation of the ilmenite grade entering the flotation operation, and the amount of ore is not stable, the operation is difficult for employees, and the recovery rate of ilmenite metal is generally low. The metal recovery rate of iron tailings is generally only 12-14%. [0004] 2. The current production process of Pangang Mining Co., Ltd.: the +0.10mm particle size will be separated by gravity-electric separation process; -0.10mm will be separated by a strong magnetic-flotation process. The metal recovery rate can only reach 20-22%, and the technological p...
