Preparation of ultrafine silica from potash feldspar using sodium carbonate roasting technologyJia-nan Liu1,Xiao-yi Shen1,Yan Wu1,Jun Zhang1,Yu-chun Zhai1,21. School of Metallurgy, Northeastern... residue. The leaching solution was then carbonated to yield ultrafine silica. The optimized reaction conditions in the roasting process were as follows: an Na2CO3-to-potash feldspar molar ratio......
Upgrading and dephosphorization of Western Australian iron ore using reduction roasting by adding sodium carbonateDe-qing Zhu1,Tie-jun Chun1,Jian Pan1,Li-ming Lu2,Zhen He11. School of Minerals... microscopy and scanning electron microscopy. It is found that phosphorus exists within limonite in the form of solid solution, which cannot be removed through traditional ways. During reduction roasting......

of Aeronautics and Astronautics, Nanjing 210016, China) Abstract: With reference to the foreign two-stage variable speed transmission configuration, a two-stage variable speed helicopter transmission..., and the low-speed path of the two-stage planetary gears has better load sharing characteristics. At the same time, the dynamic characteristics of the system can be improved by increasing the input......
. Aluminosilicates disperse or symmetrically immerse inside goethite. The existential relation between iron and aluminium in the ore is very complex. Magnetic separation and magnetization roasting-magnetic separation are unable to remove aluminum effectively because they are unable to destroy the isomorphous structure of the ore. However, most of aluminum can be removed by sodium-salt-added roasting......
