Energy conservation and pollution abatement at phosphorus furnaces
A process and product of waste recovery at phosphorus furnaces is disclosed wherein small sized discrete particles of carbonaceous material or beneficiated phosphate ore are mixed with a mineral acid, an alkaline fluid and water, and the reacted mixture is tumbled in a horizontal cylinder at a temperature below that at which the carbonaceous material oxidizes to form agglomerates which are then indurated to discrete particulate size as desired for a charge component; the agglomerates are fed to a phosphorus smelting furnace together with other materials needed to make elemental phosphorus, furnace gases are cooled with recirculating water, a side stream of the water is taken off , treated, and used as feedstock in fluid fertilizers. Apparatus is disclosed for agglomerating coke and phosphate and; further, for measuring the abrasion and shatter resistance of agglomerates.
