Title
(EN) DETERMINING ORE CHARACTERISTICS
(FR) DÉTERMINATION DE CARACTÉRISTIQUES DE MINERAI
Abstract
(EN)
Techniques for processing ore include the steps of causing an imaging capture system to record a plurality of images of a stream of ore fragments en route from a first location in an ore processing facility to a second location in the ore processing facility; correlating the plurality of images of the stream of ore fragments with at least one or more characteristics of the ore fragments using a machine learning model that includes a plurality of ore parameter measurements associated with the one or more characteristics of the ore fragments; determining, based on the correlation, at least one of the one or more characteristics of the ore fragments; and generating, for display on a user computing device, data indicating the one or more characteristics of the ore fragments or data indicating an action or decision based on the one or more characteristics of the ore fragments.

L'invention concerne des techniques de traitement de minerai comprenant les étapes consistant à amener un système de capture d'imagerie à enregistrer une pluralité d'images d'un flux de fragments de minerai en route d'un premier emplacement dans une installation de traitement de minerai à un second emplacement dans l'installation de traitement de minerai ; corréler la pluralité d'images du flux de fragments de minerai avec au moins une ou plusieurs caractéristiques des fragments de minerai à l'aide d'un modèle d'apprentissage automatique qui comprend une pluralité de mesures de paramètres de minerai associées à la ou aux caractéristiques des fragments de minerai ; déterminer, sur la base de la corrélation, au moins une caractéristique parmi la ou les caractéristiques des fragments de minerai ; et générer, pour un affichage sur un dispositif informatique d'utilisateur, des données indiquant la ou les caractéristiques des fragments de minerai ou des données indiquant une action ou une décision sur la base de la ou des caractéristiques des fragments de minerai.
