ABSTRACT:
An apron for use by persons working with precious metals, particles of which are dispersed as work is performed, comprises a sheet of combustible material having particle-trapping capabilities and means for fastening the sheet of material to the upper body of a person whereby particles dispersed come into contact with the sheet of material and are trapped. A method for recovery of precious metal particles produced by persons working with precious metal alloys comprises the steps of trapping the precious metal particles on the sheet of combustible material worn by the person working with the precious metal alloys, burning the sheet of combustible material containing the entrapped metal particles to produce an incinerated mass and refining the incinerated mass to separate and purify the constituents of the precious metal alloys.
