PURPOSE:To prepare a composition, stabilized for a long time and of practical fluidity by using iron sand, water and a dispersant stabilizer as constituting components and using carboxymethylcellulose as the dispersant stabilizer. CONSTITUTION:An iron sand dispersion stabilized slurry-like composition is prepared by containing iron sand, water and methylcellulose as a dispersant stabilizer. The viscosity of 1% solution of carboxymethylcellulose to be used at 25 deg.C is preferably 1,000cps or more. The blend ratio of said composition is preferably in the range of 55-85pt.wt. of iron sand, 45-15pt.wt. of water, and 0.05-1.0pt.wt. of dispersant stabilizer. The composition thus prepared is uniform and stabilized for a long time and of practical fluidity.
