In the early 1970s they were dissolving Florida in sulfuric acid to make superphosphoric acid for the USSR. They also had a nifty process to reduce phosphate rock to elemental phosphorus vapor and then ignite that in the presence of oxygen and steam to make pure phosphoric acid. I had the personal pleasure of seeing the machined reaction head for the pilot plant. You wouldn't think something the size of a cauliflower could embarrass so many high-ranking people so thoroughly. -- Alan "Uncle Al" Schwartz UncleAl0@ix.netcom.com ("zero" before @) http://www.ultra.net.au/~wisby/uncleal.htm (Toxic URL!
