矿物型稀土矿的选矿工艺研究进展

Research Progress of Beneficiation Technology for Mineral-type Rare Earth Ore

为了促进稀土选矿技术的进步,便于从业人员系统了解稀土选矿方法,从矿物组成和矿石性质角度出发,分别介绍了磁选—浮选、磁选—重选、重选—浮选、磁选—重选—浮选以及单一浮选等稀土矿常见选矿方法的研究与应用情况,认为分析掌握原矿的矿物组成及矿石性质对选择稀土选矿工艺至关重要。

In order to promote the progress of rare earth mineral processing technology and make it easy for the practitioners to understand the rare earth mineral processing methods systematically,the com⁃mon methods of rare earth mineral processing are summarized from the aspects of mineral composition and ore properties,including magnetic separation-floatation,magnetic separation-gravity separation,gravity separation-floatation,magnetic separation-gravity separation-floatation,and single floatation process.The research and application of these methods show that it is very important to analyze and master the mineral composition and ore properties of raw ore for selecting rare earth mineral processing technology.
