Description

Verfahren zur gleichzeitigen Herstellung von Eisenphosphid und Schmelzzement. Es ist bekannt, daß bei der Verarbeitung von Phosphaten im elektrischen oder Schachtofen eine entsprechende Menge Phosphor sich an das Eisen als Eisenphosphid lagert. Bekannt sind FeBP bis Fe.P mit einem technischen Gehalt an Phosphor von etwa 16 bis 23 Prozent P.Process for the simultaneous production of iron phosphide and molten cement. It is known that when phosphates are processed in electric or shaft furnaces, a corresponding amount of phosphorus is deposited on the iron as iron phosphide. FeBP to Fe.P are known with a technical content of phosphorus of about 16 to 23 percent P.

Es ist ferner- bekannt, der Reduktionsschmelze so viel Eisenerz usw. zuzugeben, daß sämtlicher Phosphor an Eisen gebunden bleibt. Wenn man nun über diese Menge an eisenhaltigen Zuschlägen hinausgeht und außerdem, je nach der Zusammensetzung des zu verschmelzenden Rohphosphates, noch weitere Zuschläge in Form von Aluminium-, Calcium- :oder Si;licii;umoxvden oder von allen zusammen hinzugibt, so äaß einerseits sämtlicher Phosphor an Eisen als Eisenphosphid gebunden wird und ferner die Zusammensetzung der Schlacke derjenigen eines hoch-Zvertigen Schmelzzementes entspricht, so erhält man neben Eisenphosphid, welches Phosphorsäure sowie andere Phosphorverbindungen ergeben kann oder als solches eine Marktware darstellt, außerdem noch Schmelzzement als wertvolles Nebenprodukt.It is also known to add so much iron ore, etc. admit that all of the phosphorus remains bound to iron. Now when you come across this Amount of ferrous supplements goes beyond and moreover, depending on the composition of the rock phosphate to be fused, further surcharges in the form of aluminum, Calcium: or Si; licii; umoxvden or all of them added together, so ate on the one hand all phosphorus is bound to iron as iron phosphide and also the composition the slag corresponds to that of a high-strength molten cement one next to iron phosphide, which is phosphoric acid and other phosphorus compounds can result or represents a market commodity as such, as well as molten cement as a valuable by-product.

Dieses Verfahren hat dank der Tatsache, daß durch das Eisen sämtlicher Phosphor gebunden wird und infolgedessen keinerlei Spuren von Phosphoroxyden ungünstig auf die Schlacke wirken können, noch den Vorzug, daß man es ohne weiteres in der Hand hat, dem Schmelzzement von vornherein diejenige Menge an Eisenoxyd hinzuzugeben, die für eine gute Qualität desselben notwendig ist.This method has thanks to the fact that through the iron all Phosphorus is bound and as a result no traces of phosphorus oxides are unfavorable can act on the slag, nor the advantage that it can be easily found in the Hand has to add the amount of iron oxide to the molten cement from the outset that which is necessary for a good quality of the same.

Geht man von vornherein von Aluminatphosphaten als Rohstoff aus, so braucht man außer dem Eisenzuschlag nur noch Kalk und Kieselsäure zuzusetzen.If one assumes from the outset that aluminate phosphates are the raw material, then In addition to the iron addition, you only need to add lime and silica.
