Embodiment 1

[0039] The experiment was carried out at 30 °C:

[0040] (1) Take three batches of 500g titanium extraction tailings X, Y, and Z into beakers, and use 500mL tap water S-1 to sequentially wash the titanium extraction tailings X, Y, and Z for 10 minutes, and vacuum Filter under the condition of 0.09Mpa to obtain filter residues X-1, Y-1, and Z-1. The obtained filtrate is recovered to be processed;

[0041] (2) Use 500mL tap water S-2 to stir and wash the filter residues X-1, Y-1, and Z-1 in sequence for 10 minutes respectively, and filter under the condition of a vacuum of 0.09Mpa to obtain the filter residues X-2, Y-2 , Z-2. The obtained filtrate and 500g titanium tailings Y 1 (The fourth batch of titanium extraction tailings) was stirred, washed and filtered to obtain the filter residue Y 1 -1, the obtained filtrate is recovered to be processed;

[0042] (3) Use 500mL tap water S-3 to filter residue X-2, Y-2, Z-2 and Y in sequence 1 -1 were stirred and washed for 10 minu...

Embodiment 2

[0046] (1) Take 1500g of titanium extraction tailings X into a beaker, stir and wash with 1500mL tap water for 10min and filter to obtain filter residue X-1. The obtained filtrate is recovered to be processed;

[0047] (2) The filter residue X-1 was stirred and washed with 1500 mL of tap water for 10 min and then filtered to obtain the filter residue X-2. The obtained filtrate is recovered to be processed;

[0048] (3) The above filter residue X-2 was stirred and washed with 1500 mL of tap water for 10 min and then filtered to obtain filter residue X-3. Wherein, after drying the filter residue X-3, a titanium extraction tailings product having a chlorine element content of 0.05% by weight is obtained.

[0049] (4) Combine the above filtrates and place them until the natural evaporation volume is about 1000 ml. Add milk of lime to the filtrate to be treated continuously and slowly under stirring to adjust the pH of the filtrate to 10. After stirring for 5 minutes, remove the ...

Abstract

The invention provides a processing method of titanium extraction tailings. The titanium extraction tailings contain a water soluble chloride; the method includes washing the titanium extraction tailings with water, so that the content of chlorine elements in the processed titanium extraction tailings is below 0.06 wt%. Through the processing method of the titanium extraction tailings, the titanium extraction tailings with the chlorine element content below 0.06% can be obtained.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of vanadium and titanium resources, in particular to a treatment method for titanium tailings. Background technique [0002] Titanium tetrachloride is an important intermediate raw material for producing sponge titanium and titanium dioxide. High titanium slag (TiO 2 The content is about 90%) mixed with carbon powder, and chlorination reaction with chlorine gas under high temperature (about 950 ℃) conditions to produce titanium tetrachloride. [0003] The slag (commonly known as "blast furnace slag") produced by Panzhihua Iron and Steel (Group) Company using vanadium-titanium magnetite for blast furnace smelting, in which TiO 2 The content is about 20%), and the blast furnace slag is smelted with carbon at high temperature to obtain carbide slag. Under normal circumstances, TiC, the main reaction component of carbide slag, can undergo chlorination (commonly known as "low temperature chlo...
