Known at home and abroad sepiolite clay deposits can be divided into cream product? Hydrothermal and sedimentary two categories. Sedimentary sepiolite sepiolite clay mineral deposits are the main type of industry. It also sub-continental sedimentary deposits and marine sedimentary deposits of two subtypes. (1) cream product? Hydrothermal ore deposit types of sepiolite clay This type of sepiolite mostly white or gray fiber assembly, the fiber length is generally greater than 10 m, with a silk luster, Mohs hardness of 2 or so, and has high flexibility, quality more Pure, very strong water absorption. This type of ore deposit in general were compact block, color lighter, with a composition containing high quality than those of sedimentary so good. However, this type of deposit tend to be small, sepiolite are also often local enrichment, generally can not form industrial deposits, some for local small-scale mining. Main ore types are fibrous minerals (sepiolite ore plant in Anhui Quanjiao Ma), according to components are divided into: (1) fibrous sepiolite minerals. These minerals formed almost by a single sepiolite, sepiolite content is as high as 90%. (2) Opal? Sepiolite fibrous minerals. Mainly by sepiolite, opal composed of sepiolite content is 30 ~ 80%. (B) of the sedimentary deposits of the ore type sepiolite Generally compact block, earthy mineral, clay mineral particles smaller, difficult to identify visually. Sepiolite mineral dispersed content greater accumulation in up to 50 ~ 80%. Often associated with carbonate minerals, magnesium montmorillonite, attapulgite, talc, sulfate minerals, and halides such as symbiotic or associated. Deposit scale, up to large and medium. Continental sedimentary sepiolite deposits are generally higher than the formation of a new era, are more complex mineral paragenesis. Sepiolite content of high and low, large changes in chemical composition. Marine sedimentary deposits containing more than seam occurs in Sui limestone, marl, chert and other marine strata, the ore sepiolite content is higher, the larger the deposit, is currently China's industrial economic significance of the largest sepiolite deposit types. Weathered rocks by calcium and magnesium levels can be divided into different ore types: clay-type sepiolite clay and sepiolite original rock type two (Hunan Liuyang county Yonghe sepiolite deposit). 1. The original rock type sepiolite clay The type of calcium and magnesium from the shale, marl, and rock composition of sepiolite clay, and weathered a major sepiolite clay minerals are similar, the difference is that the original rock type in the calcite content higher, and there a small amount of quartz, talc and dolomite, celestite. 2. Sepiolite clay type This type is made of the original rock type, weathering, was gray, light gray, dark brown, Zi Hui and other colors, as the earthy, with weak silk gloss, Zhixi Ni, adhesive strength, good plasticity, low density ( 1.68g/cm3 so), highly fragmented, loose structure, poor cementation, easy hydrolysis. Major minerals sepiolite, quartz, talc, calcite, a small amount of montmorillonite, kaolinite, chlorite, and organic matter. Such ores has better mud performance and bleaching performance, and other physical and chemical properties, is the only application which can provide a sepiolite ore types.
