Group 1 - In 2024, global copper production is projected to reach 23 million tons, representing a year-on-year increase of 1.77%, primarily driven by contributions from the Democratic Republic of the Congo and Indonesia [1] - Global electrolytic aluminum production is expected to grow by 2.86% to 72 million tons in 2024, with China being the largest producer at 43 million tons, accounting for 59.72% of the total, an increase of 140,000 tons from 2023 [1] - Global lead ore production is forecasted to decline by 1.60% to 4.3 million tons in 2024, with China's lead ore production at 1.9 million tons, representing 44.19% of the global total [1] Group 2 - Zinc production is anticipated to continue its downward trend, decreasing by 0.83% to 12 million tons in 2024, with China contributing 33.33% of global zinc production [4] - Despite a general growth trend in global nickel production, it is expected to slightly decline by 1.33% to 3.7 million tons in 2024 due to the impact of low-cost nickel products from Indonesia, leading to production cuts in Australia and the Philippines [4] - Global tin production is projected to decrease by 1.64% to 300,000 tons in 2024, with major production concentrated in China, Indonesia, Peru, and Myanmar [4] Group 3 - China's copper, aluminum, lead, and zinc reserve-to-production ratios are significantly lower than the global average, with China's copper reserve-to-production ratio at approximately 22.78 years, compared to the global average of 42.61 years [7] - China's copper reserves account for only 4.18% of global reserves, totaling 41 million tons, with challenges including small ore bodies, low grades, and high extraction costs [7] - The aging of mines and declining ore grades are expected to impact China's copper production, which is projected to decrease by 1.1% to 1.8 million tons in 2024 [7]
