6501 is a non-ionic surfactant. When the anionic surfactant is acidic, the thickening effect is particularly obvious when it is compatible with it. It can be compatible with a variety of surfactants. It is mainly used in the manufacture of shampoos and liquid detergents. At present, there is no literature It is clearly recorded that 6501 is used as a foaming agent in zirconium-titanium flotation

Embodiment 1
[0024] The flotation of zirconium-titanium ore was carried out with 6501 (namely coconut oil fatty acid diethanolamide) as the foaming agent. The method of use is as follows:
[0025] Add water to minerals (mass ratio 1:1) to make slurry, add water glass, stir for 5 minutes, add soda ash, stir for 5 minutes, add caustic soda, stir for 5 minutes, then add oleic acid, stir for 3 minutes, and finally add 6501.
[0026] Among them, 400 grams of water glass, 200 grams of soda ash, 100 grams of caustic soda, 100 grams of oleic acid and 30 grams of 6501 are added to each ton of minerals.
Embodiment 2
[0028] The flotation of zirconium-titanium ore was carried out with 6501 as the foaming agent. The method of use is as follows:
[0029] Add mineral water (mass ratio 1:2) to make slurry, add water glass, stir for 10 minutes, then add soda ash, stir for 10 minutes, then add caustic soda, stir for 10 minutes, then add oleic acid, stir for 5 minutes, and finally add 6501.
[0030] Among them, 600 grams of water glass, 500 grams of soda ash, 300 grams of caustic soda, 300 grams of oleic acid and 50 grams of 6501 are added to each ton of minerals.
Embodiment 3
[0032] The difference from Example 2 is: 500 grams of water glass, 300 grams of soda ash, 100 grams of caustic soda, 200 grams of oleic acid and 50 grams of the flotation foaming agent are added to each ton of minerals.

Abstract
The invention discloses an application of an efficient environment-friendly flotation foaming agent. A 6501 surface active agent is used for uhligite flotation, on one hand, the foaming agent is poisonless, tasteless and free from the problem of environmental pollution, on the other hand, the effect of the foaming agent is superior to that of 2# oil, the surfaces of tank bottom minerals such as zircon sand and rutile can be cleaned, and the foaming agent is an ideal novel foaming agent for uhligite flotation. The 6501 surface active agent is used as the foaming agent to obtain bulk concentraterich in ZrO2 and TiO2, ZrO2 content is 31-37%, and TiO2 content is 50-60%. Compared with a raw ore, the foaming agent has the advantages that the recovery rates of ZrO2 and TiO2 reach 90-99%, and flotation effects are excellent.
Description
technical field [0001] The invention relates to the application of a flotation foaming agent and belongs to the technical field of mineral flotation. Background technique [0002] Flotation is a commonly used beneficiation method for metallic ore and non-metallic ore. In order to improve the product quality of zircon sand and rutile, it is a common method to treat zircon sand and rutile concentrate by reverse flotation. The flotation foaming agent is 2# oil, which is expensive and has an unpleasant smell, which has a negative impact on the environment of the concentrator. [0003] 6501, the chemical name is coconut oil fatty acid diethanol amide, the English name is Coconut Diethanol Amide, CDEA for short. 6501 is a non-ionic surfactant. When the anionic surfactant is acidic, the thickening effect is particularly obvious when it is compatible with it. It can be compatible with a variety of surfactants. It is mainly used in the manufacture of shampoos and liquid detergents. ...
