  • equipment used for fire assay ore sample

    A commonly used procedure to isolate metals from the ore is fireassay, which leaves a matrixfree "button" of the metal. This button is then dissolved in the appropriate acids and analyzed. By knowing the amount of sample used in the sample preparation and the analytical results, the concentration of the metals in the ground can be determined.
