Describe the formation of kaolin on kaolin Hill
The kaolin deposits as foundation, according to the difference of geological and geographical conditions, deposit size, morphology and occurrence characteristics of ore bodies, ore material composition embodied different mineralization, geological exploration "standards" will be divided into kaolin ore kaolin deposits China into three types and six sub types.1, weathering type: can be divided into weathering residue subtype and weathering drench accumulation subtype;2. Hydrothermal alteration: they are divided into hydrothermal alteration subtype and modern hot spring alteration subtype;3, sedimentary type: divided into sedimentary and sedimentary weathering sub - type and coal bearing strata, kaolinite, clay rock subtype
Kaolin is a kind of clay mineral is very important in nature, and is in the acidic medium lack of alkali metal and alkaline earth metal, formed by igneous and metamorphic rocks in the feldspar or other silicate minerals by weathering.Soil classificationThe minerals contained in kaolin in nature are mainly divided into clay minerals and non clay minerals. The clay mineral mainly contains kaolinite group minerals and a small amount of montmorillonite, mica and chlorite; non clay minerals include feldspar, quartz and the hydrate, and some iron minerals such as hematite, siderite, limonite, titanium minerals such as Jin Hongshi and organic matter such as plant fiber etc.. Clay minerals are the main minerals that determine the properties of kaolin.
Its pure kaolin is white, fine and soft, and it has good plasticity and fire resistance. The mineral composition is mainly composed of mineral kaolinite, halloysite, illite, illite, montmorillonite and quartz, feldspar etc.. Kaolin is widely used, mainly used for papermaking, ceramics and refractories, secondly used in coating, rubber filler, enamel glaze and white cement raw materials, a small amount of paint, paint, plastic, used for grinding wheel, pencil, soap, cosmetics, pesticide, medicine, textile, petroleum, chemical industry, building materials, defense and other industrial sectors.
Kaolin is a nonmetallic mineral, a kind of clay and clay rock mainly composed of kaolinite group clay minerals. Because of the white and delicate, also known as "white cloud soil.". [name] because of kaolin village, Jiangxi, Jingdezhen province.
