Claim Text:
1. A method for manufacturing a reconstituted stone raw material by using a molten slag, comprising steps performed sequentially: introducing the molten slag into a pool for preserving heat; maintaining a temperature of the molten slag in the pool at 1450-1600° C.; adjusting a composition and/or a color of the molten slag in the pool according to requirements of a resulting product by adding color modifier; wherein the molten slag is directly discharged from a metallurgy reactor or is a remelted slag, wherein the molten slag includes 10-40 wt % of Al controlling a temperature of the molten slag at 1400° C.-1500° C. while performing a cast-molding process with the molten slag thereby producing a cast-molded slag; and maintaining the cast-molded slag at a temperature of 800° C.-1000° C. for 1-5 hours in a non-reducing atmosphere, and then; gradually cooling the cast-molded slag to a room temperature within 2-5 hours to obtain the reconstituted stone raw material.
