The Silver Extraction Process

The silver that remained at the bottom of the cupel was run-off and solidified into blocks. Since lead was also valuable, it was recovered by placing the litharge lead oxide remaining from the cupellation process into yet a third furnace and heated to 250 degC and air was blown through it. The lead was run-off and formed into rods.

Silver Processing The Metal And Its Alloys Britannica

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.

Mercury mining has ceased altogether in Spain, which until 1989 was the worlds largest producer. In the United States, mercury mining has also stopped, although small quantities of mercury are recovered as part of the gold refining process to avoid environmental contamination.

Strip Mining An Overview Sciencedirect Topics

Andrew P. Schissler, in Encyclopedia of Energy, 2004 2.3 Strip Mining. Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling.
