The present invention provides a magnesia-spinel refractory in which corrosion resistance and slag penetration resistance are significantly improved. The magnesia-spinel refractory is obtained by mixing magnesia granulated powder having a particle diameter of 10 to 150 µm and alumina powder having a particle diameter of 0.1 to 5 µm, molding the resultant mixture, and then burning the molded product to form a dense and strong combined structure of periclase and spinel. The mixture of magnesia and alumina contains powders of both components, or a powder of one of the components and a granulated powder of the other component. It is preferable to use a spray dryer method as granulating means, and a hydrostatic pressing method as molding means. These mixtures are used for producing magnesia-spinel protecting tube and crucible, bricks for copper smelting and converting furnaces, and magnesia-spinel protecting tube and crucible for copper smelting and converting furnace slag. In this case, the hydrostatic pressing method is used.
