Silver processing The metal and its alloys Britannica

2020-8-15  Silver processing Silver processing The metal and its alloys: Even silver that has been fully work-hardened, either by rolling or forging, gradually recrystallizes, even at room temperature. This greatly softens the metal, making it susceptible to scratching and marring. To maintain hardness, therefore, other metals are added to form alloys that are harder, stronger, and less prone to fatigue.

Processing of High-Silver Gold Ores ScienceDirect

2016-1-1  As silver elutes ahead of gold, it would be expected to have little effect on the design of the elution circuit. However, the data in Table 45.2 indicate enhanced silver recoveries at higher elution temperatures for the Anglo-American Research Laboratories (AARL) elution process. The base data from which this table is constructed were derived at the AARL in Johannesburg and are therefore
