摘要
阴离子捕收剂MG-2是以某脂肪酸为原料合成的一种带过氧羟基的新型捕收剂。通过单矿物浮选试验研究了MG-2对石英的捕收性能,并与原脂肪酸进行了比较。试验结果显示,MG-2对石英的捕收能力优于原脂肪酸,并且其捕收能力随过氧化值P提高而增强,同时其耐低温性能较原脂肪酸有了明显的提高。红外光谱分析表明,MG-2在石英表面的吸附为化学吸附。
Modified anionic collector MG-2 is a new peroxide hydroxyl collector which is synthesized with fatty acids as raw material. In the flotation tests on single mineral, the collecting performance of MG-2 on quartz is investigated, which are compared with the original fatty acids. The test results show that the collecting performance of MG-2 is superior to the original fatty acids. And its collecting ability is increased with the increase of oxidation value P and meanwhile its low temperature resistance performance is greatly improved, compared with the original fatty acids. The infrared spectrum analysis shows that MG-2 has a chemical adsorption in quartz surface.
