phosphate deposits contain more uranium oxide than other domestic phosphate rock; therefore, the wet-process phosphoric acid made from this phosphate rock is an attractive source of uranium oxide. The Uranium Recovery Corp. (URC) completed in 1976 an $8 million complex at Mulberry, Florida, to extract uranium using its own solvent extraction

Land-pebble phosphate, hard-rock phosphate, and river-pebble phosphate are the three types of phosphatic rock found in Florida. This report is concerned primarily with the land-pebble deposits, the only type which contains a significant amount of uranium. The most productive part of the land-pebble district is in Polk and Hillsborough Counties, in the west-central part of the Florida peninsula.

The Bureau of Mines investigated the recovery of vanadium, uranium, and phosphorus from low-grade phosphorite ores and concentrate by leaching with h2so4. Samples containing 0.12 to 0.23 pct v2o5, 0.009 to 0.012 pct u3o8, and 18 to 30 pct p2o5 were treated by batch- agitation leaching, roasting followed by acid leaching, salt- roasting followed ...
