2010年至2024年间智利采矿能耗增长54%

Core Insights - Chile's copper production is projected to increase only by 1.6% from 2010 to 2024, while mining energy consumption is expected to rise significantly by 54% during the same period [1] Industry Overview - The primary reason for the disparity between copper production and energy consumption is the aging of mines, leading to a decline in ore grades, which necessitates the processing of more rock and longer transportation distances [1] - Open-pit mining energy consumption has surged by 79%, and energy consumption in the beneficiation process has increased by 89% [1] Energy Consumption Projections - By 2024, total energy consumption in Chile's mining sector is anticipated to reach 199,000 terajoules, with electricity and fuel consumption nearly equal [1] - The industry is accelerating its transition to green energy, with 78% of copper mining's electricity consumption expected to come from renewable sources in 2024; this figure is even higher for large mining companies at 96%, and medium-sized companies have increased from 57% in 2023 to 84% [1] Future Outlook - Experts predict that by 2034, the industry's electricity demand will continue to grow, reaching 32.5 terawatt-hours [1] - With the expansion of seawater desalination facilities and the electrification of beneficiation processes, electricity consumption from seawater is expected to increase by 145%, while fuel consumption is projected to gradually decline between 2030 and 2035 based on the decarbonization roadmaps set by mining companies [1]
