  Decomposition of bastnasite and monazite mixed rare earth …

  201221 · The leaching solution was analyzed after the calcined ore was washed, filtered and dissolved with acid. The decomposing ratio of rare earth is shown in Table 2. Compared with the ore calcined at 500 ºC without alkali, it is obvious that the decomposing ratio of the rare earth concentrate without al- kali is only 37.16%, which is relatively low.

  The silicothermic reduction of magnesium in flowing

  202091 · The calcined dolomite, ferrosilicon and fluorite were sieved with 100 mesh, respectively. With Si/2MgO mol ratios of 1.2 and CaF 2 mass fraction of 3%, all powders were evenly mixed and moulded with the forming pressure of 150 MPa. The briquette with a thickness of 0.72 mm was divided into small masses to test.

  HIGH-TEMPERATURE STUDIES OF METALLURGICAL …

  2024530 · The rate of reaction (a) has been studied over the temperature range 1140–1460 °C, by following the loss in weight of the reactants in high vacuum.The loss in weight of the reactants was found to be greater than that which can be accounted for by the above reaction. The excess weight loss was found to be due to a brownish, glassy …
