Electrochemical flotation control in recent years, a major progress in sulfide ore flotation technology. The main content is to reveal the essence of the flotation process by electrochemical principle and to establish the function relationship between dosage and electrochemical parameters of each operation point in the process. In the flotation process, various electrochemical parameters such as pH and potential are continuously measured online. According to the established mathematical model to adjust the dosage, optimize the pharmaceutical system, in order to improve the dressing index. Ion-selective electrodes are required for the laboratory research and flotation process of electrochemically controlled flotation. At home and abroad, the research and production of ion-selective electrodes are very important. The varieties of ion-selective electrodes commercially available in the United States are characterized by variety, stable quality, response time, repeatability and service life. Unfortunately, the high price of 300-600 US dollars each. This article compiled the following information on the United States has commercialized ion-selective electrode for the development or selection of ion-selective electrode reference.
