    Assaying Ores to determine gold content Nevada Outback

    A century ago, the fire assay and a few other methods were the only ones used. Today advanced equipment analyzes a variety of samples not just by fire assay, but by atomic absorption, mass spectroscopy and other specialized techniques. When you are doing anything with hard rock materials, sampling and assaying are the key concepts.
