PRECIOUS METAL ANALYSIS Accurate and precise precious metal analysis can be performed by using fire assay, cyanide leach, aqua regia or INAA. Precious metal analysis is usually determined by using either a lead or nickel sulphide fire assay pre-concentration step prior to analysis. This is required to separate the precious metals from the matrix
