| <P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a new potassium phosphate compound fertilizer capable of validating a phosphoric acid component contained in incinerated ashes of poultry dung by improving its solubility and at the same time having a powdery form with good handling that is obtained by neutralizing an alkali derived from a lime component, and a new potassium phosphate compound fertilizer. <P>SOLUTION: The problem can be solved by adding an alkaline earth metal compound to incinerated ash powder of poultry dung, adding a mineral acid to this so as to cause a neutralization reaction between the added alkaline earth metal compound powder and the added mineral acid, raising the temperature of the reaction system by utilizing the heat build-up at the neutralization reaction, accelerating a reaction between the mineral acid and a lime component or the like contained in the incinerated ash of poultry dung, converting a phosphoric acid component to a citric acid-soluble phosphate, and at the same time keeping the product in a neutral or weakly acidic range. <P>COPYRIGHT: (C)2007,JPO&INPIT | ||||||

| In particular to improve the physico-mechanical properties of granular fertilisers and in order to increase the efficiency of the application of alkaline, alkaline earth-elements and group IV elements, the invention provides a method for producing granular fertilisers comprising at least one structural compound based on at least one salt with the steps of disposing of at least one salt comprising nitrogen, humidifying the at least one salt, mixing the at least one humidified salt with at least one substance comprising at least one alkaline and/or alkaline-earth element and/or at least one element of the forth period of group IV, producing a granular fertiliser by granulation of the mixture, and cooling the granular fertiliser. The invention further provides a granular fertiliser comprising nitrogen and having a ph in the range of 3 = pH = 7. The granular fertiliser shows a strength σ of σ = 3 Mpa and an entire amount csc of at least one structural compound with csc = 50 wt. -%. | ||||||

| PHOSPHATE ROCK IS DECOMPOSED BY TREATMENT WITH SOLUTION OF ACID SELECTED FROM THE GROUP OF ACIDS NAMED IN THE SPECIFICATION, USING A PROPORTION OF ACID SUFFICIENT TO SUBSTANTIALLY COMPLETE THE DECOMPOSITION OF THE CALCIUM FLUOPHOSPHATE OF THE USED PORTION OF THE PHOSPHATE ROCK. THERE IS PROVIDED AND USED IN THE ACID TREATMENT OF THE PHOSPHATE ROCK A REACTING COMPOUND OF ALUMINUM USED IN THE PROPORTION STATED IN THE SPECIFICATION, WITH THE RESULT THAT THE FLUORINE OF THE TREATED PHOSPHATE ROCK CHEMICALLY REACTS AND COMBINES WITH ALUMINUM OF THE USED COMPOUND OF ALUMINUM TO FORM A COMPOUND OF ALUMINUM AND FLUORINE. SEPARATE COMPOUNDS OF (1) SUBSTANTIALLY FLUORINE-FREE ARTIFICIAL PHOSPHATE AND (2) OF ALUMINUM-FLUORINE COMPOUND OF RESULT, WHICH MAY BE RECOVERED SEPARATELY IN AN ARIFICIAL PHOSPHATE PRODUCT AND A SOLID FLUOALUMINATE PRODUCT. SULPHUROUS ACID FORMED WHEN A STREAM OF GAS FROM COMBUSTION OF A SULPHUR-CONTAINING SUBSTANCE IS BROUGHT INTO AN AQUEOUS SOLUTION, MAY BE USED AS THE ACID OF TREATMENT OF PHOSPHATE ROCK, MYSELF HAVING DISCOVERED THAT WHILE PHOSPHATE ROCK IS REFRACTORY TOWARD SO-OBTAINED SULPHUROUS ACID, PHOSPHATE ROCK IS CHEMICALLY DECOMPOSABLE BY SUCH SOLUTION OF SULPHUROUS ACID CONTAINING A REACTABLE ALUMINUM COMPOUND. AS A RESULT OF MY DISCOVERY THE RECOVERY AND UTILIZATION OF SULPHUR DIOXIDE FROM GAS STREAMS RESULTING FROM THE BURNING OF SULPHUR-CONTAINING SUBSTANCES IS MADE PRACTICAL AND USEFUL. NEW AND USEFUL PHOSPHATE PRODUCTS RESULT FROM THE USE OF MY SAID DISCOVERY.
