The new - process has been worked out on an approximately commercial basis at the department's experimental plant! at Arlington, Va. Comes Largely from Florida The phosphate used for fertilizer In the United.States comes lvirgely from the deposits of rock in Florida. There are also large deposits in Tennessee e and a number of beds in South Caro lina, where the rock was first exploit ed for this purpose. The established method for producing soluble phos phate has consisted in treating the rock with sulphuric acid. In practie, a quantity of sulphuric acid equal to the quantity of rock is used, and the resulting product, which is known as acid phosphate,' contains only one-half the percentage of phosphoric acid con tained hi the rock from which it was derived. Commercial acid phosphate, for instance, made from a 32 per cent rock contains only 16 per cent of phos phoric acid. The elaborate washing and screening process now used in preparing phosphate rock for treat ment with sulphuric acid often results in the loss of two-thirds of the rock, and it was with a view to saving this Immense waste of phosphate that the new process was evolved. The United States Department of Agriculture has been experimenting for some time along the lines of free ing the phosphoric acid by means of/ a high degree of heat. It was the first to adapt the Cottrell precipitator to the collection of phosphoric acid, the apparatus having been previously de vised by Dr. Cottrell to abate, the smoke nuisance and to recover sul phuric acid from smelting operations. The first work was done in an electric furnace which was though to be re-' quired to generate the high degree of heat necessary, about 1,600 C. or 2,- I 900 F. At this temperature mixtures of phosphate rock, sand, and coke were reduced to a molten slag which was tapped off at intervals, the phosphoric acid escaping in the form of fumes which were afterwards collected in a liquid or solid form. It soon became evident that this I process would be prohibitively expen sive with an electric furnace, except in localities where electric power could be obtained at a ver ylow cost, about 0 $25 per horsepower a year ,and the de partment thercfore turned its atten tion to the possibilities of using crude oil, the cheapest fuel obtainable in the~ vicinity of the large phosphate-rock dleposits ot F'loridla. The efforts have recently met with success, and figures kept on the experimen'tal runs at Ar lington indicate that phosphoric acid can be extracted more cheaply in an oil-burning furnace than by the old i One p~hroblem wich department scientists have wvorkedl out is that of keeping the fuel in dlirect contact with the rock material until the reaction is wellstated.Forthis purpose, and terial is briqueted with coke and sand. Briqueting- keeps the coke fuel with-I in the mass and retains it until the r eaction is wvell started. Sand or sili (a is necessary to bring about the chemical reactions and this sand is *largely present as an impurity in the F'loida p~hosphate deposits, togetherI with a claycy ingredient which acts as an excellent binder in making the *briquettes. Thus the very impurities which make rock objectionable under *the old pr~ocess are turned into an as Eset. - U The practical value of the new de-I velopment is indicated by the fact that Uin the experimental runs at ArlingtonI the depairtment chemists wvere able to recover a 64 per cent phosphoric acid (17 pcr cnt P. 0.) as against the 16 Upe r cent prodluct ordinlaril yobtainedl byv the sulphuric-acidl process.
