WebLead is extracted from ores dug from under-ground mines. Lead is also found in conjunction with other metals such as silver and zinc. Lead materials are mined as a by- product of these other more valuable metals. Extracting the lead materials from the ore is a tedious process. First the lead ore is ground into small salt-like particles. WebThe patio process is a process for extracting silver from ore. Smelting, or refining, is most often necessary because silver does not very frequently occur in the nature by itself as a native element mineral like some metals nobler than the redox couple 2 H + + 2 e − ⇌ H 2 (gold, mercury, ...).Instead, it is made up of a larger ore body. Thus, smelting, or refining, …

WebExtracting silver from argentiferous lead in ancient times required oxidising the lead to litharge by heating the molten lead to temperatures of about 1000°C under a stream of air (Craddock 1995, 205-33; L'Heritier et al. 2015). With a melting point of 888°C, litharge is molten and oxidises base metals readily, which dissolve in it.
