Summary:
u, Au, and Mo deposits, such as the Miami-Inspiration and the Cu Resolution.
The area is built of igneous, metamorphic and sedimentary rocks of various ages from the early Proterozoic to the Tertiary.
The Carlota deposit is formed by the surface mineralization of copper oxides in the proterozoic Pinal Schist. Chrysocolla is a dominant ore mineral and usually occurs as coatings, crusts and filling in fractures and heavily desintegrated rock masses.

Beneficiation
- Sulfuric acid (reagent)
- Heap leach
- Solvent Extraction & Electrowinning
Summary:
he pregnant leach solution (PLS) is pumped out of the heap and after the initial mechanical cleaning is subjected to the SX process, followed by the EW electrowinning process. The end product is electrolytic copper in the form of cathodes.
Summary:
r. Rainwater that has been in contact with the mine is captured and then used in technological processes.
