摘要
近年来,基于扫描电镜的矿物自动分析仪如QEMSCAN(Quantitative Evaluation of Minerals by Scanning Electronic Microscopy)、MLA(Mineral Liberation Analyser)和AMICS(Advanced Mineral Identification and Characterization System)已经广泛应用于矿物的自动识别与测量;激光剥蚀等离子质谱仪(LA-ICP-MS)由于其在痕量上的检测优势,使元素赋存状态的研究更加准确与深入;飞行时间二次离子质谱仪(TOF-SIMS)的应用为研究矿物表面特性及其变化提供了便利和可靠的方法。部分大型矿山企业在地质勘查阶段就对不同区段的样品进行工艺矿物学研究,关注矿石性质的空间变化给选矿工艺及指标带来的影响,为及时优化改进工艺流程提供依据和指导。就目前研究成果而言,矿物自动测量与分析技术的不断完善,建立数学模型预测选矿指标以及矿物三维数据表征技术在工艺矿物学研究中的应用是其持续发展的新趋势和方向。
In recent years,automated mineral analyzer based on SEM such as QEMSCAN,MLA,AMICS have been widely used in mineral automatic identification and measurement. Because of its advantages in trace detection,laser ablation plasma mass spectrometry（ LA-ICP-MS） has made the study of the occurrence state of elements more accurate and thorough. Time of flight secondary ion mass spectrometry（ TOF-SIMS） provides a convenient and reliable method for the study of the surface characteristics and change. In the geological exploration stage,based on the process mineralogy research of the sample in different sections,some large mining enterprises pay attention to the influence of the changes in the ore properties on the beneficiation process and indicators. In terms of the present research results,continuous improvement on automatic measurement and intelligent mineral analysis technology,mathematical model to forecast the index of mineral processing,and mineral 3D characterization technology in process mineralogy are the new trends of sustainable development and direction.
