The invention provides a process for producing mass colouration float glass by furnace slag powder, which comprises the following steps of: A, weighing the following raw materials in percentage by weight: 3 to 6 percent of furnace slag powder, 50 to 60 percent of silica sand, 16 to 20 percent of soda, 9 to 13 percent of dolomite, 3 to 6 percent of limestone, 3 to 6 percent of feldspar, 0.3 to 0.8 percent of mirabilite and 0.01 to 0.05 percent of carbon powder; B, sequentially adding the raw materials into a mixer according to the sequence and uniformly mixing the raw materials to obtain a mixture; and C, melting, forming and annealing the mixture at a high temperature of 1,600 DEG C by a melting furnace to obtain the mass colouration float glass. In the process provided by the invention, furnace slags discharged as the waste in the metallurgical industry are utilized; after being processed, the furnace slags are applied to a production line of the mass colouration float glass as a colouring additive; and othe
