بيت /separation of calcium oxide by magnetic field
Calcium hydride is commonly used as a strong reducing agent and is used to produce hydrogen when working in the field. Preparation method: metal calcium is charged into an iron pot, heated to about 300 ° C with electric heat or oil, and reacted with hydrogen to prepare calcium hydride.

Magnetic separation technique was preferred due to its suitability for magnetic ore and simplicity. The magnetic separation was performed in two stages. At the first stage 8 different samples were ground to different fineness in centrifuge ball mill and concentrated by the Davis tube (Fig. 1). The applied magnetic field of the Davis tube was T.
