Abstract
The invention discloses a titanium-containing concentrate recovery method. According to the invention, titanium-containing furnace slag is subjected to crushing, sieving and iron removing; the slag is subjected to acid dissolution with hydrochloric acid, such that metal elements expect silicon and titanium in the slag are dissolved in hydrochloric acid, and titanium oxide and silicon oxide can be separated in a form of solid precipitate; after filtering, the filter slag is added into a sodium hydroxide solution and is subjected to alkali dissolution, such that silicon is dissolved in the alkali solution, and titanium exists in a form of a precipitate metatitanic acid; and filtering and drying are carried out, such that the titanium-containing concentrate is obtained. With the method provided by the invention, titanium in titanium-containing furnace slag can be separated, and other valuable elements can be separated and extracted in subsequent processes. The recovery effect is good, and the resource is effectively utilized.

(2) acid-soluble: by above-mentioned treated slag with 20-35% hydrochloric acid carry out acid-soluble, acid-soluble temperature is 30-60 DEG C, the acid-soluble time is 10-60 minutes, and keep solution Ph value to be 2-5, the metal oxides such as the calcium magnesium-aluminum-iron in slag are all dissolved in hydrochloric acid, titanium then precipitates with the form of silicon-dioxide with metasilicic acid, silicon, then filters, by for subsequent use for titaniferous filter residue and drying;
(3) alkali is molten: the above-mentioned throw out through drying treatment being joined concentration is that to carry out alkali in the sodium hydroxide solution of 10-50% molten, alkali solubility temperature is 50-100 DEG C, the alkali molten time is 1-6 hours, and keep solution Ph value to be 8-10, make the silicon-dioxide in throw out fully be converted into Starso and enter into solution, filtration, drying, obtain titaniferous enriched substance metatitanic acid.
The recovery method of a kind of titaniferous enriched substance of the present invention, its most preferred technical scheme is:
(1) raw material: Ti-containing slag is first simply sorted removal of impurities process, then carries out fragmentation with Raymond mill, carries out sorting deironing with magnetic separator;
(2) acid-soluble: by above-mentioned treated slag with 20-35% hydrochloric acid carry out acid-soluble, acid-soluble temperature is 45 DEG C, the acid-soluble time is 30 minutes, and keep solution ph to be 3, the metal oxides such as the calcium magnesium-aluminum-iron in slag are all dissolved in hydrochloric acid, titanium then precipitates with the form of silicon-dioxide with metasilicic acid, silicon, then filters, by for subsequent use for titaniferous filter residue and drying;
(3) alkali is molten: the above-mentioned throw out through drying treatment being joined concentration is that to carry out alkali in the sodium hydroxide solution of 35% molten, alkali solubility temperature is 65 DEG C, the alkali molten time is 3 hours, and keep solution ph to be 9, make the silicon-dioxide in throw out fully be converted into Starso and enter into solution, filtration, drying, obtain titaniferous enriched substance metatitanic acid.
Compared with prior art, the titanium in Ti-containing slag not only can be separated by the present invention, and other valuable elements can also be carried out continuation separation and Extraction, its recovering effect is good, efficiently utilizes resource.
