一、概况高电压分离(high tension separation)也叫做高电压选矿法,是从静电选矿法发展出来的选矿法之一,适用于成分复杂的重矿物的选矿。最近在日本对它的工业应用受到人们的注意。众所周知,静电选矿法是在粒状混合物中的某些物质进入静电场以前或者在进入静电场的时候使共表面负有电荷,根据共电荷符号, I. Overview High tension separation (high tension separation), also called high voltage dressing method, is one of the beneficiation methods developed from the electrostatic separation method and is suitable for the processing of complex heavy minerals. Recently, its industrial application in Japan has drawn people’s attention. As we all know, electrostatic beneficiation method is in the granular mixture of some substances into the electrostatic field before or when entering the electrostatic field so that the total surface negative charge, according to the common charge sign,
