The invention discloses a method for efficiently extracting uranium and molybdenum from wrapped type uranium-molybdenum ores in a boiling roasting mode and belongs to the chemical industry field and the metallurgy field. The technology comprises the following steps that (1) crushing is conducted, specifically, the wrapped type uranium-molybdenum ores are crushed and ground; (2) boiling roasting isconducted, specifically, boiling roasting treatment is conducted through a boiling furnace; and (3) leaching is conducted, specifically roasted ores are subjected to sulfuric acid leaching after being cooled. According to the method for efficiently extracting uranium and molybdenum from the wrapped type uranium-molybdenum ores in the boiling roasting mode, boiling roasting is conducted through the boiling furnace, materials exchange heat with hot air in the boiling furnace in a boiling state, the temperature of the materials rises rapidly, the heating efficiency is high, the surface structures of difficultly-soluble
