Abstract: A binder for agglomerating an ore in the presence of water, contains 10% to 90% of a water-soluble sodium carboxymethylhydroxyethylcellulose and 10% to 90% of sodium carbonate. A process comprises mixing a binder composition containing cellulose and sodium carbonate, water, and the ore, agglomerating the mixture into wet balls, drying the wet balls, and heating the resultant dry balls at a temperature of at least about 1204.degree. C. A preferred ore is taconite.
