In this paper, the general classification of sedimentary type uranium ores in China and their relationship to leaching characteristics is studied. It has been found through tests that five distinct characteristic types of minerals belonging to sedimentary type uraniferous ore i.e., carbonates minerals,clay minerals, sulphides minerals, fossile organic matter and apatite are of major technological and economical significance to the selection of leaching method and technological parameters. Hence, the division...

In this paper, the general classification of sedimentary type uranium ores in China and their relationship to leaching characteristics is studied. It has been found through tests that five distinct characteristic types of minerals belonging to sedimentary type uraniferous ore i.e., carbonates minerals,clay minerals, sulphides minerals, fossile organic matter and apatite are of major technological and economical significance to the selection of leaching method and technological parameters. Hence, the division of sedimentary type uraniferous ores into eight classses is proposed as follows: ( 1 ) uranium ore amenable to acid leaching with low contents of the above minerals;

Titanophlogopite megacrysts occur in alkali basalts in Mt. Fushan, Dangtu County, Anhul Province. Inclusions of spinel-lherzolite and megacrysts of augite, garnet and anorthoclase are recognized in the rocks as well.Optical, minerochemical and wave-spectroscopic data on the Ti-phlogopite are presented in this paper. Chemically it is characterized as being Ti- and Fe~*-rich. Its refractive index is obviously higher than that of phlogopites of various occurrences. X-ray diffraction pattern features strong reflection on the odd basement layers and weak one on the even basement layers. Polytype is 3T. These characteristics show that the titanophlogopite was formed under high pressure condition.

钛金云母巨晶产于安徽当涂釜山的碱性玄武岩中,在该岩石中还含有尖晶石二辉橄榄岩包体和辉石、石榴石和歪长石巨晶。 本文提供了钛金云母的光性特征、矿物化学和波谱学等方面的资料。其化学特征是富钛和铁。其折光率显著高于各种产状的金云母。X射线衍射谱的特征是基底奇数层反射强,而偶数层反射不明显。多型为3T型。这些反映了钛金云母在高压条件形成。
