    It allows for the use of relatively large quantities of ore sample from which trace quantities of noble metals are concentrated. The fire assay with lead as the collector is one such procedure, where preconcentration of the noble metals allows for direct analysis of the noble metals in lead The samples may be prepared by pyrochemically treating the ore sample with a litharge-based flux.
