The precious metal containing products and materials submitted into the refining process are generally called: "precious metal scrap" (<xr id="fig:Examples_of_precious_metal_scrap"/><!--(Fig. 11.2)-->). They are usually classified into three categories which differ by the refining processes (<xr id="fig:Processes_for_the_refining_of_precious_metal_scrap"/>) employed and by the cost-to-value ratio.
