由于科学技术和现代工农业的发展,非金属矿产的新类型和新用途正在不断发现和扩大,日益增多的矿物、岩石进入工业领域。现将当前国内外概况简介于后。一、用于具有隔热、隔音、防火、防震等特性的轻质建筑材料的矿产迅速发展目前,用于轻质骨料和板材的天然矿物和岩石多达20余种,如:珍珠岩、沸石岩、浮石、凝灰岩、火山渣、膨胀粘土、页岩、板岩、半石墨、蛭石、硅藻土、煤矸石、石棉及石膏等。它们的产量年增长率达5～15%。
Due to the development of science and technology and modern industry and agriculture, the new types and new uses of non-metallic minerals are constantly being discovered and expanded, and an increasing number of minerals and rocks have entered the industrial field. Now introduce the current situation at home and abroad. 1. Rapid development of minerals for light building materials with properties such as heat insulation, sound insulation, fire prevention, and shock proofing. At present, there are more than 20 natural minerals and rocks used for lightweight aggregates and plates, such as perlite, Zeolite, pumice, tuff, volcanic slag, expanded clay, shale, slate, semi-graphite, vermiculite, diatomaceous earth, gangue, asbestos and gypsum. Their annual growth rate of production is 5 to 15%.
