Title
(EN) MICROFLUIDIC DEVICE AND METHOD FOR ANALYSIS OF A PARTICULATE SAMPLE
(FR) DISPOSITIF MICROFLUIDIQUE ET PROCÉDÉ D'ANALYSE D'UN ÉCHANTILLON PARTICULAIRE
Abstract
(EN) The present invention relates generally to devices able to manipulate, process, treat, sort, measure and/or analyse samples at a micro level, commonly referred to as microfluidic devices. In particular, the present invention relates to a microfluidic device that can be used for the analysis of particulate samples, such as by the leaching at a micro level of a crushed rock particulate sample from a mineral ore body and the subsequent analysis of the leachate. The present invention also relates to a method for the use of a microfluidic device for the analysis of a particulate sample.
(FR) La présente invention concerne d'une manière générale des dispositifs aptes à manipuler, traiter, examiner, trier, mesurer et/ou analyser des échantillons à un niveau micrométrique, communément appelés dispositifs microfluidiques. En particulier, la présente invention concerne un dispositif microfluidique qui peut être utilisé pour l'analyse d'échantillons particulaires, par exemple par lixiviation à un niveau micrométrique d'un échantillon particulaire de roche broyée à partir d'un corps de minerai minéral et l'analyse ultérieure du lixiviat. La présente invention concerne également un procédé d'utilisation d'un dispositif microfluidique pour l'analyse d'un échantillon particulaire.
