Patent

CA 2414524

The invention provides a method of assaying a mineral sample for determining the concentration of selected metals in a sample comprising the steps of providing a comminuted mineral sample; mixing such sample with a flux; preheating a reaction vessel to a temperature which approximates the melting point of the flux; introducing the mixture of the mineral sample and flux into the crucible, whereby the mixture is transformed to a molten state to capture the metal to be assayed in a collector material; and separating slag from the collector material.

L'invention concerne un procédé servant à analyser un échantillon minéral afin de déterminer la concentration de métaux sélectionnés, ce qui consiste à utiliser un échantillon minéral broyé, à mélanger cet échantillon avec un flux, à préréchauffer un réservoir de réaction à une température s'approchant du point de fusion du flux, à introduire le mélange constitué par l'échantillon minéral et le flux dans le creuset, ce qui permet de transformer ce mélange jusqu'à son état de fusion afin d'extraire le métal à analyser dans un matériau collecteur puis à séparer les scories de ce matériau collecteur.
