Gold extraction – Wikipedia
Gold extraction or recovery from its ores may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.

It contains an even greater depth of industrial information, focussing on how copper metal is extracted from ore and scrap, and how this extraction could be made more efficient. Leaching, solvent extraction and electrowinning are evaluated together with their impact upon optimizing mineral resource utilization.
Hydrometallurgical processing of impurity streams generated during the pyrometallurgy of copper – Patent – 5616168 – PatentGenius
Hallmark features of the various embodiments of this invention include the water leach of flue dust, a controlled acid leach stage in which metal species are solubilized, the extraction of copper as a sulfide, and the ability to operate the various process stages at essentially ambient pressure.
SciELO South Africa – Journal of the Southern African Institute of Mining and Metallurgy – Gas-phase extraction of lead and …
The extractions of iron or lead from their minerals both follow pyrometallurgical routes. A few examples include iodine (titanium, zirconium), carbon monoxide (nickel), and hydrogen chloride (tin, copper, and iron). Pyrometallurgical extraction makes it difficult to extract these metals from low-grade sources.

OSHA – Secondary Lead Smelter eTool – Lead – Definitions
Dross refers to the lead oxides, copper, antimony, and other elements that float to the top of the molten lead. It is a substance used to aid in the extraction of a furnace charge because of its ability to fuse with undesired matter (impurities/contaminants) in forming a more liquid slag.
