The invention discloses a decomposition recovery and utilization process for magnesium residues. According to the technical scheme, the decomposition recovery and utilization process is characterized by comprising the following steps that (1), feeding is performed; (2), water injection and soaking are performed; (3), stirring and hydration are performed; (4), water injection is stopped, and the magnesium residues are removed; (5), a liquid fusing agent stands still, and precipitation is performed; (6), after precipitation is completed, the liquid fusing agent is layered, clear water on the upper layer is pumped to a workshop by a water suction pump and is used for a cooling water pool, sediment precipitated on the lower layer is fished out and air-dried, sampling and analysis are conducted after air-drying, and qualified products are marked with batch numbers. By the adoption of the decomposition recovery and utilization process, the technical problems existing in the prior art are solved, a lot of magnesium
