115,441. Giesecke, C. Oct. 4, 1916. Briquetting and agglomerating processes.-Fine ores, flue dust, purple ore, iron filings, and the like are mixed with coal washings or colliery slimes, the mixture is formed into briquettes or lumps, and these are sintered in a shaft furnace with finely divided fuel distributed in the interstices between the briquettes or lumps. The slimes may contain a large amount of clay, and some finely divided fuel together with the slimes may be mixed with the ores, &c. By working so as to heat and cool the charge quickly, a sintered crust is obtained on the briquettes or lumps.
