Embodiment 1
[0019] (1) Prepare raw materials according to the following mass percentages:
[0020] C12 fatty acid 25%, N-chlorosuccinimide 15%, alkyl ether amine 20%, octanol and dodecyl alcohol 15%, emulsifier (OP-10) 6%, diesel oil 8%, water is 11%;
[0021] (2) Put the C12 fatty acid and N-chlorosuccinimide in the step (1) into the reactor for chlorination reaction at a temperature of 120°C for 4 hours, then add ether amine, and React for 45 minutes, then add industrial fusel alcohol, and stir evenly, then add emulsifier and diesel oil, add water after stirring evenly, and obtain a microemulsion homogeneous viscous liquid, which is a cationic collector for phosphate rock flotation.
[0022] When the obtained phosphate rock flotation cationic collector is used, the cationic collector is first diluted with water into a collector solution with a mass concentration of 3%, and then the collector solution is used as iron removal for the phosphate rock in Haikou, Yunnan. , In the reverse fl...
Embodiment 2
[0025] (1) Prepare raw materials according to the following mass percentages:
[0026] C16 fatty acid 30%, N-chlorosuccinimide 5%, acyl ether amine 25%, n-butanol and myristyl alcohol 20%, emulsifier (Tween-80) 10%, diesel oil 5%, water 5%;
[0027] (2) Put the C16 fatty acid and N-chlorosuccinimide in the step (1) into the reactor for chlorination reaction at a temperature of 90°C for 3 hours, then add etheramine, and React for 30 minutes, then add industrial fusel alcohol, and stir evenly, then add emulsifier and diesel oil, add water after stirring evenly, and obtain a microemulsion homogeneous viscous liquid, which is a cationic collector for phosphate rock flotation.
[0028] When the obtained phosphate rock flotation cationic collector is used, the cationic collector is first diluted with water into a collector solution with a mass concentration of 2%, and then the collector solution is used as iron and aluminum removal for phosphate rock. In the reverse flotation proc...
Embodiment 3
[0031] (1) Prepare raw materials according to the following mass percentages:
[0032] C18 fatty acid 15%, N-chlorosuccinimide 8%, ether amine 50%, hexanol 5%, emulsifier (polyether) 2%, diesel oil 1%, water 19%;
[0033] Wherein, ether amine is alkyl ether amine and acyl ether amine;
[0034] (2) Put the C18 fatty acid and N-chlorosuccinimide in the step (1) into the reactor for chlorination reaction at a temperature of 100°C for 5 hours, then add etheramine, and React for 60 minutes, then add industrial fusel alcohol and stir evenly, then add emulsifier and diesel oil, add water after stirring evenly, and obtain a microemulsion homogeneous viscous liquid, which is a cationic collector for phosphate rock flotation.
[0035] When the obtained phosphate rock flotation cationic collector is used, the cationic collector is first diluted with water into a collector solution with a mass concentration of 5%, and then the collector solution is used as iron and aluminum removal for p...
