Description
In dem Hauptpatent ist ein Verfahren zur Gewinnung von Molybdän, Wolfram, Titan, Vanadin und anderen seltenen Metallen aus Ausgangsstoffen beschrieben, in denen sie neben größeren Mengen anderer, im Wege des Steinschmelzens gewinnbarer Metalle in geringen Mengen enthalten sind. Das Verfahren beruht darauf, daß den Stoffen beim Steinschmelzen Eisen oder Gemische, aus denen sich Eisen bilden kann, zugesetzt werden. The main patent describes a process for the extraction of molybdenum, tungsten, titanium, Vanadium and other rare metals are described from starting materials in which they are in addition to larger quantities of other metals that can be extracted by stone melting in small amounts are included. The method is based on the fact that the substances at Iron or mixtures from which iron can form can be added to stone melts.
Es hat sich nun gezeigt, daß man bei diesen Verfahren das Eisen oder die Gemische, aus denen sich Eisen bildet, durch andere zur Eisengruppe gehörige Metalle, wie z. B. Nikkei, oder durch Legierungen solcher Metalle mit Eisen oder endlich durch Gemische ersetzen kann, aus denen im Prozesse selbst solche Metalle oder Legierungen erzeugt werden. It has now been shown that in this process, the iron or the mixtures from which iron is formed by other metals belonging to the iron group, such as. B. Nikkei, or by alloys of such metals with iron or finally by mixtures from which such metals or alloys are produced in the process itself.
