The rock texture , mineral occurence feature , ore electronmagnetic milling and applied possibilities in ceramics and glass of the jadeite metamorphic aegirine - augite nepheline syenite in suizhou , hubei were studied . the results show that the ore deposit combines the advantages of mining and milling , and the finished ore by single electronmagnetic milling may be fully utilized as the raw materials for ceramics and glasses . meanwhile , another important fact is that the compositon with 90 percent raw ore may be manufactured into the wall and floor tiles with glaze , which was affirmed by a lot of experiment research 隨州硬玉質變霓霞正長巖的巖石組織結構、礦物賦存狀態、礦石可選性和玻璃陶瓷原料應用試驗研究表明:該資源具有易采易選兩大優點,礦石經單一磁選的精礦可作玻璃和陶瓷的原料;同時已反復試驗證實該資源可燒成原礦用量達90的釉面墻地磚。

Abstract : syenite is an important raw material in glass and ceramic industry . we got the bottle glass and construction ceramics using yaoan syenite and others . the technological flowsheet of production and the mineralogical composition and property of the glass and ceramic materials were studied in this paper 文摘:本研究擬開發利用云南姚安及其周邊地區正長巖、石英砂、粘土等非金屬礦產資源,將其作為制備陶瓷或玻璃的主要原料,經過一定的加工和制備工藝,得到建筑陶瓷制品或玻璃,確定采用本地區的非金屬礦產資源原料制備建筑陶瓷制品或玻璃的工藝參數。
