大型塔式磨机在金精矿氰化细磨中的应用

塔式磨机是一种垂直安装、筒体固定及内带螺旋搅拌装置的搅拌型细磨设备。由于金精矿中金、银颗粒比较细，金、银矿物大多以连生体和包裹体形式与黄铁矿共存，需要对金精矿进行充分研磨，提高磨矿细度，使金、银颗粒充分裸露，达到单体解离的效果。在金精矿氰化过程中，解离度的大幅提高，可使金、银浸出彻底，氰化回收率随之提高。塔式磨机具有能耗低、磨矿粒度细、噪音低、占用空间少、易维护、便于安装及磨矿效率高等优点，因此是金精矿氰化细磨的理想磨机。

Application of Large Tower Mill in Cyanide Fine Grinding of Gold Concentrate

Tower mill is a type of fine grinding equipment with vertical fixed installation,cylinder fixed and helical mixing device.Because gold and silver particles is fine in gold concentrate,and most of gold and silver minerals with even had body and inclusions form coexist with pyrite,fully grinding of gold concentrate is necessary in order to improve grinding fineness,make gold and silver particles fully naked,and achieve the effect of monomer dissociation.During the process of cyanide gold concentrate,due to the large increase in degree of dissociation,gold and silver are leached thoroughly,thus cyanide recovery.Tower grinding machine has the advantage of low energy consumption,grinding fine granularity,low noise,occupies less space,easy maintenance, easy installation and high grinding efficiency,therefore,it is ideal fine grinding mill in cyanide fine grinding.
