浮选工艺指标的变化受着许多因素的影响。其中矿石性质起着决定性的作用。因此,如何掌握矿石性质变化规律以及选择相适应的技术操作条件,是当前浮选生产中急待解决的问题。本文根据本矿有关生产资料的分析,重点探讨如何改善浮选工艺指标的问题。一、赤矿石的性质 (一)矿物组成与物理化学性质: 东鞍山铁矿床属前震旦纪变质沉积岩。矿物成分简单,主要是假象赤铁矿及少量的褐铁矿、磁铁矿和镜铁矿等。脉石以石英为主,含有少量的硅酸盐等矿物。主要矿
Flotation process changes in the index subject to many factors. The nature of the ore plays a decisive role. Therefore, how to grasp the changing law of ore properties and the technical operating conditions that are suitable for the selection is an urgent problem to be solved in the production of flotation. Based on the analysis of relevant production materials in this mine, this paper focuses on how to improve the flotation process indicators. First, the nature of red ore (a) mineral composition and physico-chemical properties: the East Anshan iron ore deposit is pre-Sinian metamorphic sedimentary rocks. Simple mineral composition, mainly illusion hematite and a small amount of limonite, magnetite and specular iron ore and so on. Quartz gangue-based, with a small amount of silicate and other minerals. The main mine
