Chile Copper Refining Industrial Infrastructure Development Feasibility Study with Mining Supply Chain Outlook

Executive Viability Abstract

This feasibility study evaluates the establishment of a state-of-the-art copper refining complex in Chile. By transitioning from the export of raw concentrates to high-purity Grade A copper cathodes, the project aims to capture higher margins, leverage the country's massive reserve base, and align with the global surge in demand for electrification materials. The study integrates a supply chain outlook considering logistical bottlenecks and renewable energy integration.

## Market Analysis Chile currently accounts for approximately 28% of global copper production, yet a significant portion is exported as concentrate. The global shift toward electric vehicles (EVs) and renewable energy grids is projected to increase copper demand by 40% by 2030. There is a specific market gap for 'Green Copper'—refined copper produced with low carbon footprints, which this facility will address using Chile's solar and wind resources. ## Technical Feasibility The facility will utilize a combination of flash smelting technology and permanent cathode electro-refining. Infrastructure requirements include a dedicated desalinated water pipeline to mitigate local water scarcity and a direct connection to the SEN (National Electrical System) to utilize the high percentage of renewable energy available in the Atacama region. ## Supply Chain Outlook The project will act as a centralized hub for multiple medium-scale mines that currently lack refining capabilities. By reducing the volume of material transported internationally (refining concentrate locally reduces mass by ~70%), the project significantly lowers freight costs and carbon emissions per ton of copper sold. ## Regulatory and Environmental Context Compliance with Chilean environmental standards (SEA) and local community agreements is critical. The design includes sulfuric acid capture (99.9% efficiency) for use in local leaching operations, creating a circular economy loop within the Chilean mining ecosystem.
