§1 引言铝土矿石是冶炼铝的主要原料,还可以用于制造研磨材料、耐火材料和高铝水泥等,在化学工业上也有重要用途。铁在铝土矿中是有害的杂质,它的含量会严重影响矿石的使用价值。河南省新安县贾沟铝土矿中的高铁矿石在豫西几乎到处可见,颇具代表性。因此,研究这类矿石中的铁的赋存状态对提供除铁方法、开发铝土矿的矿产资源有实际意义。按矿石的成因和矿物的组合划分,贾沟铝土矿的矿石可分为以下两类:1、风化淋滤型,矿石呈土黄色、疏松易碎、具砂土状结构。肉眼观察矿块呈白色豆状,多系迪开石和水
§1 Introduction Bauxite is the main raw material for smelting aluminum and can also be used in the manufacture of abrasives, refractories and aluminous cements, and is also of significant use in the chemical industry. Iron is a harmful impurity in bauxite, its content will seriously affect the value of the ore. Xin’an County, Henan Province Jiagou bauxite in the high-speed iron ore in the West can be seen almost everywhere, quite representative. Therefore, studying the occurrence of iron in such ores has practical significance for providing iron removal methods and developing mineral resources of bauxite. According to the cause of the ore and the combination of mineral division, Jiagou bauxite ore can be divided into the following two categories: 1, weathered leaching type, the ore was khaki, loose and fragile, sandy soil structure. The naked eye was observed white bean-shaped ore, and more Dikai stone and water
