Embodiment 1

[0022] Get 10g of isopropanol and 30g of epichlorohydrin and put in a 150ml round bottom flask, stir and mix well, then add 0.10g of triethylbenzyl ammonium chloride and 12ml of sodium hydroxide solution with a mass concentration of 40%, and heat to 60 ~ 65 ° C, continue to stir for 3 hours, the reaction is completed and the reaction product is cooled to room temperature. Then place the reaction product in a rotary evaporator to distill off the unreacted epichlorohydrin under reduced pressure to obtain the product chlorinated fatty alcohol ether. Take 30 g of chlorinated fatty alcohol ether and put it in a 100 ml round bottom flask, stir and slowly add 5 g of 1.0 mol / L sodium hydroxide solution, stir and react at room temperature for 50 min to obtain fatty alcohol epoxy ether. Mix sodium sulfite and sodium bisulfite at a mass ratio of 5:1 to make a saturated solution. Take 10g of fatty alcohol epoxy ether, 20g of saturated sodium sulfite and sodium bisulfite solution and add ...

Abstract

The invention discloses a mineral floatation foaming agent and a preparation method thereof. The mineral flotation foaming agent is prepared from the raw materials of fatty alcohol with a branch chain and epoxy chloropropane by epoxidation and sulfonation. One end of the foaming agent has polar groups of -OH and -SO3H, and the other end of the foaming agent has fatty alcohol sulfonate with straight chain alkyls or branch chain alkyls of different carbon atoms. The raw materials of the mineral flotation foaming agent are widely available and cheap, the synthesis process is simple, the synthesis conditions are mild, the reaction is easy to control, and the industrialization is easy to realize. The foaming agent has good aerophily and hydrophily as well as excellent foaming performance. The degradation speed of the foaming agent is higher than that of the terpineol with an annular structure, thereby being favorable for environmental protection. Compared with the existing product, the mineral recovery rate is increased by 0.5-2%, and the using cost is lowered by 10-20%.

Description

technical field [0001] The invention belongs to the technical field of ore flotation, and in particular relates to a foaming agent for mineral flotation. At the same time, the invention also relates to a preparation method of the foaming agent. Background technique [0002] Frothing agent is one of the main reagents for ore flotation. The foaming agent currently used in mines in my country is terpineol, and companies generally do not have more varieties to choose from. Therefore, when considering improving or improving the sorting index from the perspective of chemicals, people often focus on collectors, regulators, etc. Aspects of work, while ignoring the active role of the foaming agent. Long-term studies have shown that the performance of the foaming agent has a significant impact on the flotation index. Foaming agents are generally heteropolar surface active substances. The molecular structure contains polar groups, such as hydroxyl-OH, and the other end of the molecu...
