Fire Assay in the mining process
Fire assay is a method used to determine the concentration of precious metals in ores. The workflow involves sample preparation, fusion, cupellation, and measurement. Supplies required for fire assay include fluxes, crucibles, tongs, scorifiers, and furnaces. The method is accurate and widely used in the mining industry. The fire assay workflow and supplies can vary depending on the type of sample being analyzed and the desired level of sensitivity.
