Study on Mineral Processing of Bameng Cryptocrystalline Magnesite Ore;

巴盟隱晶質菱鎂礦選礦試驗研究

On the basis of studying the mineral composition of altered mylonite in zhushanxia uranium deposit,a new type of altered mylonite uranium deposit (U-W coexisting) has been found,and uranium exists as uraninite.

對竹山下鈾礦床中蝕變糜棱巖的礦物成分進行了研究，發現了一種新型Ｕ－Ｗ共生的蝕變糜棱巖型鈾礦床，鈾礦物主要是晶質鈾礦；指出相應的成礦作用為燕山早期（１６５×１０６ａ±）氣熱高溫熱液鈾成礦作用。

Among other things, exposed uraninite-rich granite is rich in silica (SiO2>70%), rich in alkalis (K2O+Na2≈8%) with K>Na (K2O:Na2≈5:3) and rich in uranium.

產鈾花崗巖出露面積大,其中有硅高(SiO2>70％),富堿(K2O+Na2O約為896),鉀大于鈉(K2O:Na2O 約=5:3),鈾含量高,含晶質鈾礦的富鈾花崗巖出露。
