Problems solved by technology

[0006] The olivine-type vanadium-titanium magnetite iron-separation tailings after stage grinding stage iron selection iron-separation tailings contain a large amount of olivine, and olivine iron content ranges from 10% to 50%, its magnetic properties and Compared with ilmenite, most of them are equivalent, and some are stronger than ilmenite, so it cannot be thrown into the tailings by strong magnetic separation, and it is difficult to separate them even by gravity separation (to maintain a high recovery rate). Throwing into the tailings, a large amount of olivine and ilmenite enter the strong magnetic concentrate at the same time, resulting in the strong magnetic concentrate TiO 2 The grade is not high, and the grade of TFe is higher (relative to the gabbro type), which brings great difficulties to flotation separation

Abstract

The invention belongs to the ilmenite flotation technology, and particularly relates to a pyroxene peridotite type ilmenite depressing agent and a preparation method of the pyroxene peridotite type ilmenite depressing agent. The preparation method of the pyroxene peridotite type ilmenite depressing agent comprises the step of carrying out oscillation, stir and curing on a mixed solution formed by sodium silicate, ferric nitrate and sulfuric acid to obtain the pyroxene peridotite type ilmenite depressing agent, wherein oscillation, stir and curing are carried out for 30-40min. The obtained pyroxene peridotite type ilmenite depressing agent comprises, by weight, 5-15 parts of the sodium silicate, 5-15 parts of the ferric nitrate and 1-10 parts of the sulfuric acid. The pyroxene peridotite type ilmenite depressing agent obtained through the preparation method has a good selective depressing effect on olivine and pyroxene, and has extremely important significance in obtaining of good technical indexes of titanium flotation of pyroxene peridotite type ilmenite.

Description

technical field [0001] The invention belongs to ilmenite flotation technology, in particular to an olivine pyroxene type ilmenite flotation inhibitor and a preparation method thereof.
