Abstract

The characterization of textural properties of minerals is closely related to the process of their respective liberation. Measurements of mineral liberation, related to grinded ore, can be performed using optical ore microscope, by conventional, classical methods – point counting, linear intercepts method or planimetric measurements method (2D). Modern automatic devices and sophisticated measurement techniques (QEMSCAN/MLA) imply recording free surfaces area of mineral grains on polished sections samples in order to determine mineral degree of liberation. Value of mineral liberation obtained over free surfaces area can be of interest to flotation concentration, although not for gravity separation or, for example, magnetic separation. The prediction accuracy for behavior of one feed ore during the concentration process depends on the method of measuring/recording mineral liberation. Considering raw materials with complex textural characteristics it is crucial which method will be applied for determination of mineral liberation respecting whether for concentration process is crucial physical or chemical method.

量化矿物释放——一种传统和新的自动化复杂技术方法

矿物的结构性质表征与其各自的解离过程密切相关。与磨矿有关的矿物解离测量可以使用光学矿石显微镜，通过传统的经典方法-点计数，线性截距法或平面测量法(2D)进行。现代自动设备和复杂的测量技术(QEMSCAN/MLA)意味着记录矿物颗粒的自由表面面积在抛光切片样品，以确定矿物的解放程度。在自由表面上获得的矿物解离值可能对浮选浓缩有兴趣，但对重力分离或磁选等没有兴趣。在选矿过程中对某一进料矿石行为的预测精度取决于测量/记录矿物解离的方法。考虑到具有复杂结构特性的原料，采用何种方法测定矿物的解离性，对于富集过程是采用物理方法还是化学方法至关重要。
