Tellurium
Domestic Production and Use: Tellurium is primarily recovered as a byproduct of the electrolytic refining of copper, where it accumulates in the residues of copper anodes. In 2022, two electrolytic copper refineries operated in the United States, one in Texas and one in Utah, and produced copper telluride from tellurium-bearing anode slimes.

Gold: History of Use, Mining, Prospecting, Assay & Production
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.

gold is a byproduct of copper production
In essentially all producing countries, the primary source of silver is its recovery as a byproduct of copper, gold, lead, or zinc production. During the 1980's, domestic mine production of silver increased to its highest level in nearly 50 years, and was due, in part, to a number of factors. أكمل القراءة

Copper Production: How Is Copper Made?
The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.
