非金属矿物原料是除金属和燃料矿产以外所有的岩石和矿物及其他天然矿产的物质,但是这并未包括全部非金属矿产,比如:(1)一部分主要作为金属原料开采的矿物像菱镁矿、铝土矿、铬铁矿、锰矿石等等。(2)某些经过加工的产品如水泥、石灰等等。(3)天然和人造产品的混合物。非金属矿物大致可分为五大类即土建原料、硅酸盐原料、化学工业原料、轻金属原料。作者列表说明了其具体内容。一、非金属矿物的广泛应用非金属矿物种类繁多,但现在广泛使用
Non-metallic mineral raw materials are all rock and mineral and other natural minerals other than metal and fuel minerals, but this does not include all non-metallic minerals, such as: (1) A part of the minerals that are mainly mined as metal raw materials like magnesite , Bauxite, chromite, manganese ore and the like. (2) Some processed products such as cement, lime and so on. (3) Mixtures of natural and man-made products. Non-metallic minerals can be broadly divided into five categories that is civil engineering materials, silicate materials, chemical industry raw materials, light metal raw materials. The list of authors explains what they are. A wide range of non-metallic minerals Non-metallic minerals a wide range, but now widely used
