Abstract
The invention discloses a method for titanium separation from high-titanium type blast furnace slag especially in the field of waste resource recycling. According to the method, other impurities and titanium dioxide in the high-titanium type blast furnace slag are effectively separated, so that the grade of the titanium dioxide is greatly improved, and the titanium dioxide in the high-titanium type blast furnace slag is reasonably used. The method includes the following steps that A, the high-titanium type blast furnace slag is put into a two-stage ball mill to be subjected to ball-milling treatment; B, the high-titanium type blast furnace slag subjected to ball-milling treatment is subjected to strong magnetism separation; and C, the high-titanium type blast furnace slag subjected to strong magnetism separation is subjected to flotation treatment. The processing steps of first magnetism separation and then flotation treatment are adopted, processing equipment is reasonably processed, the grade of the titanium dioxide is greatly improved, and the grade of the titanium dioxide is made to be larger than 45% of titanium powder.
Description
Technical field
The present invention relates to a kind of method selecting titanium in high-titanium blast furnace slag, in especially a kind of high-titanium blast furnace slag for waste resource recycling field, select the method for titanium.
Background technology
A large amount of slags can be produced in blast furnace ironmaking process, 2% can be about from the slag iron that wherein directly magnetic separation is reclaimed.Wherein dry slag (has another name called air cooling slag, hot splashing slag.Before blast furnace, build partition wall by laying bricks or stones from terrace to table height, form and sprinkle pit, slag flows in hole through slag runner after coming out of the stove, and sprawls into the thin layer of thick about 15 centimetres, water-spraying control, excavates and obtain after solidifying.) the slag iron of different grade can be obtained through techniques such as fragmentation, magnetic separation, ball millings, the slag after iron has been selected mainly to form slag sand, rubble, be mainly used in aggregate, but containing higher titanium in this part slag sand rubble, the content of titanium dioxide is about about 22%, current blast furnace slag is mainly used in the industries such as cement, but due to the content of titanium higher, significantly limit its utilization in gelling material.On the other hand, so high titanium is used for common concrete, belongs to significant wastage.In high-titanium blast furnace slag, titanium mainly exists with the form of titanium dioxide, also has the uhligite etc. of very small portion, but in slag main in dispersion, the thin feature such as real, common method is not easy to be sorted out.In addition, the titanium dioxide breeze selected will be the raw material producing the products such as titanium slag, acid sludge, titanium tetrachloride and titanium dioxide.But also there is no a kind of can effectively separation with titanium dioxide by other impurity in high-titanium blast furnace slag in prior art, thus significantly improve the grade of titanium dioxide, make the titanium dioxide in high-titanium blast furnace slag obtain selecting in the high-titanium blast furnace slag of Appropriate application the method for titanium.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of can effectively separation with titanium dioxide by other impurity in high-titanium blast furnace slag, thus significantly improve the grade of titanium dioxide, make the titanium dioxide in high-titanium blast furnace slag obtain selecting in the high-titanium blast furnace slag of Appropriate application the method for titanium.
