  • Briquetting of mill scale
    Patent number: 8444746
    Abstract: The invention relates to a method for the agglomeration of iron-oxide-containing residual materials, in particular scale and mill scale, wherein the residual materials and paper sludge are dried and ground and agglomerates are produced, by hot briquetting, from a mixture of the residual materials and paper sludge so processed. In this manner, it is possible to produce mill scale briquettes of high strength and density. These briquettes can then be charged into an electric arc steelmaking furnace for the purpose of recycling the iron contained in the residual materials.
