Non metallic mineral is how to produce? Qingzhou Guancheng company told you
非金属矿产的成因多种多样，但以岩浆型、变质型、沉积型和风化型最为重要，另外海底喷流作用也很重要，如硫铁矿主要属于这一成因。
Cause a variety of non-metallic mineral variety, but the magmatic, metamorphic type, sedimentary type and weathering type was the most important, in addition to submarine exhalation role is also very important, such as pyrite mainly belongs to the cause of.
1、岩浆作用：岩浆上侵形成侵入岩体或喷出地表后形成的火山熔岩、火山灰等，均可以形成非金属矿产资源。侵入岩体如灰长岩、花岗岩等均可做优质的建筑材料，我国著名的“将军口”花岗岩地板和产于印度的“印度红”花岗石均为钾长花岗岩；喷出地表形成的浮岩、珍珠岩都是不可缺少的工业原材料，火山灰也可以做农业用肥。还有两种特殊的岩浆岩即金伯利岩和钾镁煌斑岩，其内部含有较为丰富的金刚石。世界上大部分钻石就产于这两种岩石中。
1, magmatic intrusion of magma formation: invasion and the formation of rock or emitted from the surface after the volcano volcano lava, ash, can form a non metallic mineral resources. Intrusive rock, such as the long gray granite can do high quality building materials, China's famous "general opening" granite floors and produced in India, "India red" granite are K-feldspar granite; emitted from the surface formation of pumice, perlite are industrial raw materials indispensable, volcano ash can also do agriculture use of fertilizer. There are two kinds of magmatite special Kimberley rock and LAMPROITE, its interior contains abundant diamond. Most of the world diamond production in the two types of rocks.
2、变质作用：岩石在基本上处于固体状态下，受到温度、压力及化学活动性流体的作用，发生了矿物成分、化学组成、岩石结构与构造的变化，形成非金属矿床。工业和日常生活中常用的有石墨、石棉、蓝晶石、红柱石、滑石、云母等。山东南墅石墨矿、河南、陕西的金红石、石棉矿都是国内有名的产地。
2, metamorphism: the rock is in solid state under basically, is affected by temperature, pressure and chemically active fluid, changed the mineral composition, chemical composition, rock structure and tectonics, the formation of nonmetallic deposits. Industrial and commonly used in daily life, asbestos, graphite kyanite, andalusite, talc, mica etc.. Shandong Nanshu Graphite Deposit, Henan, Shaanxi Jin Hongshi, asbestos are domestic famous origin.
3、沉积作用：暴露于地表的岩石、矿体，在大气、水流长期作用下，发生侵蚀、搬运、分异、沉积，最终形成非金属矿产资源，也可以通过化学沉淀作用、生物化学作用直接形成非金属矿产层。主要分成三大类：（1）砂矿，主要由水流、冰川、风力等作用分选形成，如金刚石、金红石、锆石、独居石等稀有矿物均可通过这种机械分异过程，富集成矿；（2）生物化学作用，诸如磷矿就可以由鸟类的粪便直接堆积形成，硅藻土矿是由硅藻遗体堆积而成，另外还有与火山喷发有关的硫矿产等；（3）化学作用形成的盐矿，人类不可缺少的食盐、工业用的石膏、硝石，农业用的钾盐，医药用的泻利盐等均为盐湖蒸发过程中化学结晶沉淀成因。
3, sedimentation: exposure to the surface of the rock, ore, in the atmosphere, water under the long-term action, erosion, transportation, deposition, differentiation, eventually forming a non metallic mineral resources, also by chemical precipitation, biological chemistry direct formation of non-metallic mineral layer. Divided into three main categories: (1) the placer, mainly formed by water, ice, wind, sorting, such as diamond, Jin Hongshi, zircon, monazite rare mineral can be differentiation process, through the mechanical enrichment and mineralization; (2) biological chemistry, such as phosphate rock can be formed by the bird feces deposited directly, diatomite ore by diatom remains accumulation, there are also related to volcano sulfur mineral resources; (3) the chemical role in the formation of salt, the salt industry indispensable to human beings, gypsum, potassium nitrate, potassium salt for agriculture, medical use of epsom salt are the crystallization of chemical precipitation evaporation process causes the Saline Lake in the.
4、风化作用：暴露在地表的岩石或矿体，经过漫长的降雨、光照、氧化、生物作用过程，而使表层物质的化学组成、矿物面貌改变，从而形成可供利用的非金属材料。日常生活及工业中不可缺少的粘土类矿物多为这一成因，如高岭土、膨润土等均为岩石风化而成，正是这一作用为人类提供了制作陶瓷、化妆品、环境治理用品、药品、油漆等物质的原材料。扩大一点看，连万物赖以生存的土壤也是风化作用形成的非金属资源。
4, the weathering of rock or ore bodies: the exposed surface, after a long rain, light, oxidation, biological process, and chemical surface composition, mineral appearance change, thus forming a non metal material available. Daily life and industry in the clay minerals are the causes, such as kaolin, bentonite are rock weathering, it is this function provides raw material for making ceramics, cosmetics, environmental governance activities, pharmaceuticals, paints and other substances for human. Expand the point of view, even formed all things for the survival of the soil and weathering and nonmetal resources.
