Method to determine the contents of economically interesting metals in manganese nodules
Description
Metals which are economically important (as copper, nickel) can be determined in manganese nodules by analysing the activating gamma spectra which are measured after neutron irradiation of the samples. Irradiating the samples with fast neutrons and analysing the activity thus reduced with the help of a gamma detector is expected to improve the method. This serves to obtain the ratio of the radiation intensities of two main components (Mu, Fe) and using this, the percental metal content can be determined through known geo-chemical correlation tables and curves. The method is described in detail. (RB)

Wirtschaftlich interessante Metalle (wie Kupfer, Nickel) lassen sich in Manganknollen durch Analyse der Aktivierungs-Gammaspektren bestimmen, die nach einer Neutronenbestrahlung der Proben gemessen werden. Eine Verbesserung dieses Verfahrens wird vorgeschlagen, indem man die Probe mit schnellen Neutronen bestrahlt und die so induzierte Aktivitaet mit Hilfe eines Gammadetektors analysiert. Man erhaelt so das Verhaeltnis der Strahlungsintensitaeten zweier Hauptbestandteile (Mu, Fe) und daraus ueber bekannte geochemische Korrelationsdaten-Tabellen und Kurven den gesuchten prozentualen Metallgehalt. Einzelheiten des Verfahrens sind beschrieben. (RB)Files
