MAXIMIZING VALUE IN COPPER DEPOSITS BY APPLYING SORTING TECHNOLOGY *J.C Quispe1 1Digital Innovation & Studies Superintendent, Antamina Mining Company, Av. El Derby 055, Tower 1, Lima, Peru (*Presenting Author: jquispel@antamina.com) ABSTRACT The growing demand for minerals, together with declining ore grades in traditional deposits, has driven the search for innovative technologies that optimize efficiency in the extraction and processing of mineral resources. In this context, ore sorting technology has proven to be a key tool for improving the profitability and sustainability of mining operations. This process enables the early classification of minerals using advanced sensors that detect differences in physical or chemical properties, such as density, color, radioactivity, or metal content, allowing the separation of ore from waste prior to the grinding and concentration stages. The application of ore sorting significantly contributes to increasing mineral reserves by upgrading the feed grade delivered to the processing plant, thereby making previously marginal or uneconomic low-grade materials economically viable. Furthermore, it helps extend mine life by optimizing resource recovery and reducing the need for additional exploration.

INTRODUCTION Copper has become established as a strategic resource for global economic and technological development, particularly in the context of large-scale electrification and energy transition. Its physical and metallurgical properties, high electrical and thermal conductivity, durability, and recyclability make it an essential material for power grids, renewable energy systems, electric mobility, energy storage systems, advanced manufacturing, and industrial digitalization. These structural trends point to a profound transformation in global copper demand by 2050, with estimates indicating a cumulative
