How is Silver Mined - APMEX
Silver also occurs alongside lead, copper and zinc ores, which is why nearly 50% of mined Silver today is obtained when processing other kinds of ore. Silver is separated from this ore using a chemical process known as smelting. To begin a new Silver mine, a system of multi-layered crosscuts are made.
Lead and Zinc - Energy
6.1.2.3 Lead Ore Processing Lead ore beneficiating includes milling, concentration, and sintering. After sintering, the ore is smelted in a blast furnace to produce rough lead bullion. Rough lead bullion still contains many impurities. Therefore, the rough lead bullion is refined to remove and recover other metals.

Gold: History of Use, Mining, Prospecting, Assay ... - Geology
The degree of purity of native gold, bullion (bars or ingots of unrefined gold), and refined gold is stated in terms of gold content. "Fineness" defines gold content in parts per thousand. For example, a gold nugget containing 885 parts of pure gold and 115 parts of other metals, such as silver and copper, would be considered 885-fine.

The electronic waste gold contents vary from 80 to more than 800 parts-per-million (ppm), and silver contents range from 250–350 ppm; no gold or silver is observed in the automotive waste material. Consequently, the metal value of these waste materials is highly variable and can reach up to US$30,000 per tonne.

gold processing - Mining and concentrating | Britannica
Elemental gold (and silver as well) is soluble in mercury, so that, when particles of the metal are brought into contact with a fresh mercury surface, they are wetted and dissolved, forming an alloy called amalgam. This phenomenon is exploited for the recovery and concentration of fine particulate gold or silver.
