摘要
通过电子显微镜、人工重砂鉴定、X-射线衍射分析、电子探针分析技术等方法,对塘湾铀矿床进行工艺矿物学研究。查明铀矿石类型主要为硅酸盐类型矿石。铀元素主要赋存于独立铀矿物中,其中铀矿物主要为沥青铀矿,含少量晶质铀矿。脉石矿物主要为石英、长石、方解石、黄铁矿等。铀矿石结构构造以脉状、浸染状为主,铀矿物与石英、方解石、黄铁矿等矿物密切共生。其中矿石中有害组分是方解石和黄铁矿,质量分数均较高,应去除后再浸取,减少酸的消耗量。
The study on process mineralogy was carried out in Tangwan uranium deposit by means of electron microscope、identification of artificial placer, X-ray diffraction analysis and electron probe analysis methods. The types of uranium ore were primarily silicate type ore. Uranium mainly occurs in independent uranium minerals, which consisted of mainly pitchblende and a small amount of uraninite. The gangue minerals were mainly divided into silicate minerals such as quartz、feldspar, zeolite and carbonate minerals such as calcite and apatite. Uranium ore structure was given priority to vein and disseminated. Uranium minerals had a symbiotic relationship with quartz, calcite, pyrite and other minerals. The harmful compositions in the ore were calcite and pyrite with higher contents and should be leached after removing for reducing the consumption of acid.
