Silver
The greatest period of activity was before the Civil War. In 1925, 3,118 troy ounces of silver were reported recovered from processing of galena concentrates. The silver was valued at $2,194. In 1926, mining activity recovered 70 short tons of silver-bearing lead concentrates, valued at about $6,000 (combined silver and lead value).
Recovery of gold as by-product from the base-metals industries
The association of silver with lead minerals, in particular galena [PbS], is well known and documented, but gold is also frequently found in lead concentrates, and its recovery follows closely that of silver.
Silver processing | Refining, Mining & Uses | Britannica
A process routinely employed in the fire assaying of gold ores is the addition of silver prior to fusion of the ore in order to ensure that the silver content of the final bead is high enough to dissolve. This is called inquartation, and the separating of silver and gold by leaching with nitric acid is referred to as parting.
