Summary:The invention provides a manufacturing process of unfired ceramsite with red mud as a raw material, belongs to the technical field of unfired ceramsite manufacturing processes, and solves the technical problem that existing red mud causes serious pollution to the environment. Comprising the following steps: S1, removing impurities from red mud, grinding, drying, sieving with a 100-mesh sieve, adding slag and silica fume, and mixing in proportion to form a red mud-slag-silica fume three-phase raw material mixture; s2, adding cement and a CaO adhesive dry material into the three-phase raw material mixture, and uniformly mixing and stirring; s3, pouring a proper amount of Na2SiO3 solution, and forming the Na2SiO3 solution into plastic colloidal viscous mud pies; s4, taking out part of the colloidal mud pies, putting the colloidal mud pies into a cake pressing groove, and pressing the colloidal mud pies into cakes; s5, the cake-shaped object is evenly cut into jelly-shaped object long strips through a cutter; s6,
