Embodiment 1

[0017] Embodiment 1, a kind of olivine inhibitor, this olivine inhibitor is aminodisuccinic acid or iminodisuccinate, and its structural formula is:

[0018] or

[0019] Where: M is Na + , K + or NH4 + One of.

[0020] The olivine inhibitor can be used as an olivine inhibitor in ilmenite flotation. The dosage is 10~200g / t raw ore. It is mainly used for the flotation of ilmenite to suppress olivine gangue, or the flotation of other olivine-containing minerals.

Embodiment 2

[0021] Embodiment 2, a method for using the olivine inhibitor in ilmenite as described in embodiment 1, its steps include: carrying out flotation desulfurization to ilmenite, adding acid after desulfurization to control the pH of the flotation system In 2, then add the aminodisuccinic acid as a mineral inhibitor, and then add a collector to carry out the floating titanium operation. The operation process of floating titanium is rough selection. The amount of mineral inhibitor added is 10g / t raw ore.

Embodiment 3

[0022] Embodiment 3, a method for using the olivine inhibitor in ilmenite as described in embodiment 1, its steps include: carrying out flotation desulfurization to ilmenite, adding acid after desulfurization to control the pH of the flotation system In 5, then add the potassium iminodisuccinate or potassium iminodisuccinate mineral inhibitor, add an appropriate amount of other inhibitors or not, and then add a collector to carry out the floating titanium operation. The floating titanium operation process is composed of rough selection and selection. The amount of added mineral inhibitor is 200g / t raw ore.

Abstract

The invention discloses an aminodisuccinic or iminodisuccinic succinate application. The application refers to that aminodisuccinic or iminodisuccinic succinate is used as an olivine inhibitor in mineral flotation. The invention further discloses a using method of the olivine inhibitor in ilmenite; after floatation desulphurization of the ilmenite, acid is added so that pH of a flotation system iscontrolled to be 2-5; and before a flotation collector is added, the olivine inhibitor is added. The olivine inhibitor is higher in chelating capability, and stronger in adsorption to olivine; the olivine inhibitor is applied to the refractory ilmenite flotation technology, and the selective inhibition on the olivine can be enhanced; and the grade and recovery rate of titanium concentrate are improved. Meanwhile, the olivine inhibitor is liable to degrade, and soil and water pollution is not caused; and the olivine inhibitor is an environmental friendly green chemical.

Description

technical field [0001] The invention belongs to the field of ore dressing agents, and specifically relates to a new use of aminodisuccinic acid or iminodisuccinate as a mineral inhibitor, and also relates to a method for using the olivine inhibitor in ilmenite. Background technique [0002] my country's ilmenite resources rank first in the world, and more than 85% of the resources are in the Panxi region, mainly including the four major mining areas of Panzhihua, Baima, Hongge and Taihe. The types of ilmenite can be divided into gabbro type and olivine pyroxenite type. After the gabbro type ore is ground, it is easier to obtain high-grade titanium concentrate through magnetic separation-flotation. The reason is that the gangue ore The magnetism of pyroxene and feldspar is relatively weak, most of pyroxene and feldspar can be discarded by magnetic separation, and high-grade titanium concentrate can be obtained through flotation, among which the ore in Panzhihua and Taihe mini...
