Abstract

A raw material for a silicate fertilizer comprising a slag recovered in a pre-treatment process for a blast furnace hot-metal which contains silicates as oxides of silicon in the hot-metal and contains acid-soluble silicic acid in an amount of 10 mass % or more; and a method for producing the raw material which comprises adding an oxygen source to the hot-metal in the pre-treatment process for a blast furnace hot-metal to effect the oxidation of silicon, and recovering a slag containing silicates formed by the above reaction, followed by solidification, to thereby produce a slag containing acid-soluble silicic acid in an amount of 10 mass % or more. The raw material for a silicate fertilizer has a high content of acid-soluble silicic acid and exhibits low contents of alkali components and, in some cases, Al2O3, and it can be produced at a markedly reduced cost since the slag recovered in a pre-treatment process for a hot-metal can be used as it is.
