Neutral refractory ore deposit classification and distribution of China's domestic reserves of mineral resources neutral refractories, refractory materials are also widely distributed, but less worthy of exploitation. According genesis neutral refractories, refractory generally neutral neutral refractory ore deposit into schist type deposits (Chuzhou neutral refractory ore), porphyry alteration type neutral refractory deposits (Jingdezhen Willow Bay porcelain quarry), alteration of volcanic deposits in Neutral Refractories (southern Zhejiang, Fujian Nanan neutral refractories quartz rock, etc.), secondary quartzite neutral refractories illite deposits (eastern Zhejiang pyroclastic alteration neutral refractory ore type illite), clay, rock type neutral refractories illite deposits (Beijing Huairou, Southern illite clay minerals, etc.), in which the refractory ore schist Neutral exploitation maximum value, because the class feature neutral refractories refractory ore is most obvious. Exploitation of siliceous following problems compared with foreign: A, narrow the scope of application of the limitations in the vast majority of applications siliceous refractory building materials sales, the other in agriculture, there is a small amount of mechanical and electrical, chemical and environmental applications. In addition to these four foreign industrial sector, but also used in machinery, electronics, metallurgy industry, and its apparent broad application areas. B, less product variety for a particular application area, the variety of siliceous patented product is significantly less than that of foreign species refractory to agricultural applications, for example, China's only medium soilless cultivation of flowers, fruit and vegetable fertilizer and three type of patented products. And foreign siliceous patented products, including animal washers, soil improvement, many bacteria culture carrier material, pesticides carrier, feed additives and other species, more fully utilize siliceous adsorption, cation exchange properties. Gap in building materials, petroleum chemical industry is also great. C, simple processing method for the direct use of general of siliceous ore and calcined use expansion after use, simple processing method. Abroad is often used for different applications in different processing methods to produce specific grain size, density or expanded to meet the needs of different multiples of siliceous products, their method is relatively advanced processing technology, innovative, diverse refractories Which is good, but also to promote appropriate the widening and development of new products in the field of its use. D, fine-grained siliceous low utilization rate of the coarse-grained siliceous application has a good foundation, but fine (-0.3mm) silicon utilization is low, resulting in a waste of resources.
