Abstract
The authors investigate the structural and colloid properties of a collector represented by amine hydrochloride treated by ultrasound and included in sylvinite flotation. Using the viscosity–temperature dependences, the Gibbs free energy is calculated for amine hydrochloride with and without treatment by ultrasound. It is found that ultrasound-treated amine added in salt-fat solutions are more stable to coagulation. From the synchronous thermal analysis, IR spectroscopy and X-ray phase analysis, it is inferred that ultrasonic treatment of amine hydrochloride slightly increases crystallinity of amine. The research findings improve understanding of the ultrasound effect on the change in the structural and colloid properties of the collector, which are important to optimizing output, sustainability and efficiency of potassium chloride production by flotation.
摘要 作者研究了以盐酸胺为代表的捕收剂经超声波处理后在锡石浮选中的结构和胶体特性。利用粘度-温度相关性，计算了经超声处理和未经超声处理的盐酸胺的吉布斯自由能。结果发现，添加到盐脂溶液中的经过超声处理的胺对凝结更稳定。通过同步热分析、红外光谱和 X 射线相分析，可以推断出经超声波处理的胺盐酸盐会略微增加胺的结晶度。这些研究成果加深了人们对超声波影响捕收剂结构和胶体性质变化的理解，这对优化浮选法生产氯化钾的产量、可持续性和效率非常重要。
