摘要:
采用酰化法合成了N-乙酰基苯胲（简称APA）和N-丁酰基苯胲（简称BPA）捕收剂，研究了两种捕收剂对孔雀石的浮选行为及作用机理。浮选试验结果表明，在APA浓度为200 mg/L、pH=7的条件下，孔雀石的回收率可达80%；在BPA浓度为150 mg/L、pH=7的条件下，孔雀石的回收率可达85%，均优于苯甲羟肟酸。采用Zeta电位测试、XPS分析和红外光谱分析等研究了两种捕收剂与矿物表面的作用机理，结果表明，两种捕收剂与孔雀石表面的吸附主要为化学吸附。
Abstract:N-acetyl benzodiamide (APA) and N-butyl benzodiamide (BPA) collectors were synthesized by acylation method. The flotation behavior and mechanism of the two collectors on malachite were studied. Flotation experiments showed that the malachite can be obtained with 80% recovery at APA concentration of 200 mg/L and pH=7, and 85% at BPA concentration of 150 mg/L and pH=7, which were superior to benzohydroxamic acid. Zeta potential test, XPS analysis and infrared spectroscopy were used to investigate the interaction mechanism between the two collectors and mineral surface. The results showed that the adsorption of the two collectors on malachite surface was mainly chemical adsorption.
