Study on thermal decomposition kinetics of bastnaesite 氟碳铈矿热分解动力学研究
2.
Most of them take the lead on some subjects . the company is based on science and technologhy and develops continuously new products and new processes . they researched and developed a new precess " producing mixing rare earth metal directly from bastnaesite " which has advanced stage in the world and has applied for china patent 公司以科研和技术开发为基础，不断开发新产品和新工艺，研制开发了“氟碳铈矿直接电解生产混合稀土金属”这项具有国际先进水平的新工艺，并申请了专利。

The wall rock of ore - bodies is the siliceous dolostone and alkaline volcanic rock ( trachy andesite ) in the yinachang deposit . based on the shape of ore - bodies and the structure and texture of ores , the deposit was identificed as synsedimentary with wall rocks . there occurred ree minerals , such as bastnaesite , monazite and allanite , associated with apatite and fluorite with ree contents to a certain extent 矿体产出形态和矿石的结构构造等均显示矿体与赋矿地层同沉积特征；出现独立矿物氟碳铈矿、独居石及褐帘石，磷灰石、萤石、菱铁矿等矿物中也含有一定量的稀土，沿矿体走向和垂向稀土元素变化不大。
