摘要

A strong, calcined phosphate agglomerate useful as a phosphorous furnace feed is produced by crushing mine run western phosphate shale ore to substantially -1/2 inch, agglomerating the crushed shale with sufficient water to produce phosphate agglomerates having a moisture content of between about 9 to about 12% (preferably 10 to 11.5%), placing the phosphate agglomerates on a non-agitated, perforate carrier to form a feed bed, passing the feed bed on the non-agitated, perforate carrier through a calcining zone, calcining the feed bed for at least about 15 minutes at a temperature in the range of 2,000 to 2,500 DEG F, cooling the feed bed, and recovering calcined agglomerates.
