摘要
半自磨工艺具有流程简单,生产管理方便;厂房占地面积小,土建费用低;易于实现生产自动化、智能化、高效化、准确化;对高含泥含水矿石适应性强;选择性碎磨特性有利于实现有用矿物与脉石的分离;易于实现大规模生产等优点,但目前该工艺尚未在锂云母矿石选矿中应用,为了推动该工艺在锂云母矿石选矿中的应用,以江西宜春地区某代表性锂云母矿石(含泥多、风化矿多、易泥化、目标矿物嵌布粒度粗、易过磨、矿石易碎难磨)为对象,从理论、投资及运营成本上分析了此类矿石采用半自磨工艺的可行性。结果表明,二者的结合不仅理论上可行,而且从投资及运营成本上看具有一定的优势。今后业界应加大二者合理、高效融合的研究和论证,进而推动半自磨工艺在宜春地区以及类似锂云母矿石选矿中的应用。
Semi autogenous grinding process has the advantages of simple process flow and convenient production management,small occupation and low civil construction cost,easy to realize production automation,intelligence,efficiency and accuracy,strong adaptability to ore with high mud and water content,conducive to the separation of useful minerals and gangue because of the selective crushing and grinding characteristics,and easy to realize large-scale production.While the process has not been applied in the beneficiation of lepidolite ore at present.In order to promote the application of the process in the beneficiation of lepidolite ore,a representative lepidolite ore(high mud content,more weathered ore,easy to mud and over grind,which target mineral has the coarse embedded particle size,and is fragile and difficult to grind)in Yichun,Jiangxi Province is taken as the object to study about application of semi autogenous grinding process and is analyzed in terms of theory,investment and operation cost.The study results showed that the combination of the two is not only theoretically feasible,but also has certain advantages in terms of investment and operating costs.In the future,it should be increased about the research and demonstration of the reasonable and efficient integration of the two,so as to promote the application of semi autogenous grinding technology in Yichun area and similar lepidolite ore processing.
