前言选别低品位矿石时更需要确切地了解浮选现象。因此就需要探索几种新的用于研究固一液界面特性的分析测试技术。目前,只有电位滴定法、pH测定、以及耗氧量测定等方法,常用于硫化矿浮选过程的现场控制[2,3,4,5]。如分析化学用电子光谱、俄歇光谱等这样一些方法常需严格的制样处理,因而就会改变被研究界面的性质[6、7、8]。另外的几种方法(如量热法、红外光谱法和测定电动电位等),虽然制样处理不太严格,但没法在生产现场使
Preface Selects the low grade ore even more needs to know the flotation phenomenon definitely. Therefore, it is necessary to explore several new analytical techniques for the study of solid-liquid interface properties. At present, only potentiometric titration, pH measurement, and oxygen consumption determination methods are commonly used in on-site control of sulfide flotation process [2,3,4,5]. Analytical chemistry such as electron spectroscopy, Auger spectroscopy and other such methods often require rigorous sample preparation, which will change the nature of the interface being studied [6,7,8]. Several other methods (such as calorimetry, infrared spectroscopy and determination of motor potential, etc.), although the sample preparation is less stringent, but not in the production site to make
