中文摘要

低品位铁矿粉曾经主要被认为是废弃物。然而，随着对高级铁矿石需求的不断增加和铁品位的逐渐降低，目前铁矿石行业正把重点放在低品位铁矿粉的选矿上。此外，由于许多矿点缺水和各国政府新的节水政策，必须研究适当的干式选矿路线。本文评估了干式分级装置（VSK分离机）在提高两种低品位印度铁矿粉（样品1和样品2）铁含量方面的效果。矿物学研究（包括扫描电子显微镜和X射线衍射）表明，样品1是一个低品位的蓝色粉尘样品（51.2wt% Fe），样品2（53.3wt% Fe）中除赤铁矿和石英外，还含有针铁矿。采用Box–Benkhen统计设计进行了试验，结果表明，风机转速是VSK分离器中对产品质量影响最大的运行参数，其次是进料速率。在最佳操作因子水平下，样品1可得到含~55wt%铁的细粒产品，产率为~40%，而样品2可在产率为~85%的情况下升级为~56wt%铁。结果表明，VSK分选机可作为选矿回路中一种有效的中间单元操作，提高铁矿粉的含铁量。

Abstract

Abstract

With gradually diminishing Fe grade in tandem with the ever-increasing demand for high-grade iron ores, iron ore industries are now focusing on the beneficiation of low-grade iron ore fines, mainly considered waste. Besides, the scarcity of water at many of the mines’ sites and the new water conservation policies of the governments have necessitated research on suitable dry beneficiation routes. In this context, an effort has been made to evaluate the efficacy of a dry classification unit, such as the VSK separator, in upgrading the iron values of two low-grade Indian iron ore fines, named Sample 1 and Sample 2. The mineralogical studies, involving scanning electron microscopy and X-ray diffraction, suggest that Sample 1 is a low-grade blue dust sample (51.2wt% Fe) containing hematite and quartz as the major minerals, while Sample 2 (53.3wt% Fe) shows the presence of goethite in addition to hematite and quartz. The experiments, carried out using Box–Benkhen statistical design, indicate that blower speed, followed by feed rate, is the most influencing operating parameter in obtaining a good product in the VSK separator. At optimum levels of the operating factors, a fines product with ~55wt% Fe at a yield of ~40% can be obtained from Sample 1, while Sample 2 can be upgraded to ~56wt% Fe at a yield of ~85%. The results suggest that the VSK separator can be employed as an efficient intermediate unit operation in a processing circuit to upgrade the iron contents of iron ore fines.
