System and method for real-time isotope identification

An embodiment of a method for real time material identification is described that comprises determining an approximate mass value for an unknown material from spectral information derived from mass spectral analysis of the unknown material; retrieving profile models that correspond to a known material from a data structure using the approximate mass value; fitting a sample profile for the unknown material from the spectral information to the profile models to generate a fit score for each fit, wherein the lowest fit score corresponds to the best fit; calculating a mass value from the best fitting profile model and the sample profile.

ENCODING INFORMATION IN CHEMICAL CONCENTRATIONS

A method of extracting information encoded in a product includes: determining a concentration of a non-functional amount of a chemical in a product, where the concentration corresponds to one of a plurality of possible concentration ranges, where each of the plurality of possible concentration ranges indicates different non-composition manufacturing information about the product.

Sorting materials using pattern recognition, such as upgrading nickel laterite ores through electromagnetic sensor-based methods

A system and method of sorting mineral streams, for example laterite mineral ores, into appropriately classified valuable and waste streams for maximum recovery of value from the mineral stream, e.g., a stream of minerals includes receiving response data indicating reflected, absorbed or backscattered energy from a mineral sample exposed to a sensor, where the mineral sample is irradiated with electromagnetic energy. The system determines spectral characteristics of the mineral sample by performing spectral analysis on the response data of the mineral sample and identifies a composition of the mineral sample by comparing the spectral characteristics of the mineral sample to previously developed spectral characteristics of samples of known composition. The system then generates a sort decision for the mineral sample based on the comparison, where the sort decision is used in diverting the mineral sample to a desired destination e.g. pyrometallurgical treatment stages, or to a waste stream.

10101192 · 2018-10-16 · ·

Radiometric measuring arrangement for measuring and/or monitoring a measured variable, especially a fill level or a density, of a fill substance located in a container and a method executable therewith for detection of accretion formation in the container. The variable to be measured is measured by means of a measuring system, which during operation sends radioactive radiation along a measuring path through the container, and measures radiation intensity emerging from the container along the measuring path, and by means of a comparison measuring system, which sends radioactive radiation along a comparison path through the container and measures radiation intensity emerging from the container along the comparison path. The comparison path extends in such a manner through the container that in the case of the presence of an accretion layer on the inner walls of the container a ratio of a sum of the two segments of the measuring path extending through the accretion layer to the length of an additional segment of the measuring path (A, A) extending between these two segments is different from the ratio formed in the same manner for the comparison path, and an accretion formation occurring in ongoing operation is detected based on deviations ascertained in ongoing operation between the measurement results of the measuring system and the measurement results of the comparison measuring system.

Scanning method

A scanning method, which is a method of identifying a change in the density of an object, includes arranging a source of ionizing radiation and an array of radiation detectors Dn, where n is an integer from 1 to N, capable of detecting the radiation in such a way that radiation counts are counted by the detectors as the source and detectors are rotated around the object. Detectors are arranged in conjugate pairs so that missing data due to a malfunctioning detector may be filled in from its conjugate.
