摘要（英）：

The invention discloses a method for continuously measuring rare earth oxide, calcium oxide, magnesium oxide and barium oxide in a rare earth ore concentrate, and belongs to the technical field of metallurgical analysis methods. The invention aims at providing a method for continuously measuring rare earth oxide, calcium oxide, magnesium oxide and barium oxide in the rare earth ore concentrate with short analysis time, accurate measurement result, and low detection cost. The method disclosed by the invention comprises the following steps: 1, preparing a sample; 2, implementing primary sedimentation; 3, implementing secondary sedimentation; 4, preparing measurement; 5, measuring the content of calcium oxide; 6, measuring the total content of calcium oxide and magnesium oxide; 7, measuring the content of rare earth oxide; 8, measuring the content of barium oxide; 9, calculating the contents of rare earth oxide, calcium oxide, magnesium oxide and barium oxide. The method is easy to master, is high in result accuracy, and can be popularized in and applied to production. The method is suitable for rapid continuous measurement of rare earth oxide, calcium oxide, magnesium oxide and barium oxide in the rare earth ore concentrate.
