A briquet consists essentially of metallized iron fines, formed by direct reduction of iron oxide, granulated or fine silica, a carbon source such as coke breeze, and less than 3.5 percent of other components, or impurities. The briquet product has a density of from 2.0 to 6.0 g/cc, and is particularly well suited for steelmaking operations. The method for making the briquet is also disclosed.
