Copper porphyry deposits exhibit geological, mineralogical, and textural heterogeneity that affects mining and processing performance. This paper proposes a conceptual prescriptive geometallurgy framework that integrates Geology, Mining, Metallurgy, and Environmental Engineering. Geology defines domains with differentiated behavior; Mining translates them into feasible feed scenarios through sequencing, stockpiling and blending; and Metallurgy forms the core of the framework by determining the most suitable processing route and the conditions under which it should be operated. 

Flotation, conventional leaching, advanced leaching and deferred processing are considered together with variables such as P80, liberation, reagents, agglomeration, percolation and acid consumption. SIRO Minco, Jetti, Nuton and Cuprochlor-T are reviewed as technological precedents.  

The environmental component then incorporates water use, residual streams and value recovery under a circular-economy approach. Rather than establishing universal parameters, the framework establishes technical criteria to guide future evaluations of copper porphyries, particularly in the Peruvian context.
