Description

Verfahren zum Aufschluß von Titanerzen mit Salzsäure In der deutschen Patentschrift 1083 244 ist ein Verfahren zum Aufschluß von Ilmenit mit wäßriger Salzsäure, deren Salzsäurekonzentration mehr als 32 Gewichtsprozent beträgt, bei Temperaturen oberhalb 90° C beschrieben. Dieser Aufschluß wird zur Vermeidung der Hydrolyse des gelösten Titantetrachlorids unter hoher Durchmischungsintensität der Reaktionspartner durchgeführt, so daß ein hoher Ausbeutegrad des Erzes gewährleistet ist. Bei höheren Temperaturen als 100° C ist bei diesem Verfahren zur Vermeidung der Hydrolyse die Anwesenheit von Phosphorpentoxyd in Form von Phosphorsäure oder deren Salzen erforderlich.Process for the digestion of titanium ores with hydrochloric acid In the German Patent specification 1083 244 is a process for the digestion of ilmenite with aqueous Hydrochloric acid, the hydrochloric acid concentration of which is more than 32 percent by weight Described temperatures above 90 ° C. This revelation is used to avoid the Hydrolysis of the dissolved titanium tetrachloride with high mixing intensity of the Reactants carried out, so that a high degree of yield of the ore ensured is. This process should be avoided at temperatures higher than 100 ° C the presence of phosphorus pentoxide in the form of phosphoric acid or of hydrolysis their salts required.

Es wurde nun gefunden, daß der gleiche Effekt auch erreicht wird, wenn man die Salzsäure, die eine Salzsäurekonzentration von über 32"/o besitzt, durch ein Bett aus lose geschüttetem Erz, das beispielsweise Sandform besitzt, hindurchleitet. Durch diese Maßnahme wird die nach Patent 1083 244 erstrebte hohe Durchmischungsintensität des Erzes mit der Salzsäure besser erreicht, da die jeweils durch die Erzschüttung geleitete Salzsäure stets mit einem überschuß an Erz in Berührung steht. Infolgedessen ist die Geschwindigkeit der Bildung des Titantetrachlorids in Lösung wesentlich höher als nach der Arbeitsweise des Hauptpatentes.It has now been found that the same effect is also achieved if you use hydrochloric acid, which has a hydrochloric acid concentration of over 32 "/ o, through a bed of loosely poured ore, for example in the form of a sand. This measure achieves the high mixing intensity sought after in patent 1,083,244 of the ore is better achieved with the hydrochloric acid, since each is achieved by the ore bulk hydrochloric acid is always in contact with an excess of ore. Consequently the rate of formation of titanium tetrachloride in solution is essential higher than according to the working method of the main patent.

Ein weiterer Fortschritt des Verfahrens besteht darin, daß man es kontinuierlich durchführen kann, entweder in der Form, daß man die Schüttung, die von unten kontinuierlich durchströmt wird, von oben kontinuierlich ergänzt und gleichzeitig das ausgelaugte Erz unten abzieht, oder in der Form, daß man mehrere Kästen mit der Erzschüttung hintereinander von der Säure in Batterieschaltung im Gegenstrom durchströmen läßt.Another advance of the process is that you can do it can be carried out continuously, either in the form that you get the bulk that is continuously flowed through from below, continuously replenished from above and simultaneously the leached ore is withdrawn from below, or in the form of several boxes with the ore pouring one after the other from the acid in battery circuit in countercurrent can flow through.

Ein weiterer Vorteil des Verfahrens, wenn es auf die soeben beschriebene Weise kontinuierlich durchgeführt wird, besteht darin, daß man auch basische Lösungen erzielen kann, nämlich solche Lösungen, die weniger Chlorionen enthalten, als den neutralen Salzen FeCl2, FeC13 und TiC14 entspricht.Another advantage of the method when it comes to the one just described Way is carried out continuously, is that one also basic solutions can achieve, namely those solutions that contain fewer chlorine ions than the corresponds to the neutral salts FeCl2, FeC13 and TiC14.
