In Ancient Mexico, copper was not only the predominant metal but also the most extensively used base material. Between ca. A.D. 650 and 1200 or 1300, indigenous metalworkers from Michoacan, Jalisco, Colima, northwest Guerrero, and the southern parts of the state of Mexico, appear to have worked almost exclusively with native copper …

About 100 tons of ore a day were hauled to the smelter by tractor. Also, 13,000 tons of slag from earlier operations was being treated, which averaged from 2 to 10 percent copper. 147 The copper matte was hauled 25 miles to Cima (by 1916 the California Eastern had ceased operations to Ivanpah) and shipped to the smelter at Garfield, Utah.
It is generally considered that the smelting slag with an iron content of about 30%–45% and copper content of less than 1% belongs to the range of lean copper ore; a copper content with 1%–2% belongs to the range of medium copper ore; a copper content greater than 2% belongs to the range of rich copper ore (Zhou et al., 2014).
30% copper, but also contains high grade gold and silver. The gold content varies between 20 - 70 ppm, while silver is about 60 - 100 ... The melting mixture is called slag (ore slag). Reagents in the ux contain various chemical compositions such as Na 2 CO 3;PbO;SiO 2;Na 2 B 4 O 7; and CaF 2. 2.2.3 Fusion (Consolidation)
The Argaka slag heap is located in the Argaka region on the coastal plain very close to the Limni Pier, which in the 20 th century CE was used for the exportation of the ore extracted from the nearby copper mines. The slag heap was recorded, studied or sampled for chemical analysis by Zwicker, 1986, Raber, 1987, Koucky and Steinberg, …

One layer is a waste containing iron and silica compounds and is discarded as slag slagByproduct left after a desired metal is thermally separated from its raw ore.. Approximately 75 percent of the copper concentrate ends up as slag. The other layer, called "matte copper," consists of copper, iron sulfide and other metals.
Typical copper electrolyte solution produced from leaching of copper ore, contains 25–60 g/L of copper and 0.1–10 g/L of iron in the electrowinning stage (Evans, 2003; Habashi, 1998).
