Copper processing Ores Britannica

Copper processing Copper processing Ores: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.

The role of incremental magma chamber growth on ore

1. Introduction. Porphyry copper systems form in volcanic arcs above subduction zones at convergent plate boundaries by hydrothermal fluids expelled from hydrous magmatic intrusions within the upper crust (Richards, 2009; Sillitoe, 2010).They provide most of the world's Cu and half of its Mo reserves and are important sources for Au, Ag, Re, Pb and Zn (Arndt et al., 2017).

Metal-Selective Processing from the Los Sulfatos Porphyry

Sulfides extracted from porphyry-type deposits can contain a number of metals critical for the global energy transition, e.g., Co and precious metals such as Au and Re. These metals are currently determined on composite mineral samples, which commonly results in their dilution. Thus, it is possible that some metals of interest are overlooked during metallurgical processing and are subsequently

Porphyry copper deposit Wikipedia

Porphyry copper deposits are copper ore bodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself. Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name. In later stages, circulating meteoric fluids may interact with the magmatic
