中美俄铁矿石储量对比：美115亿吨，俄290亿吨，中国是多少

Group 1: Iron Ore Reserves Comparison - The United States has iron ore reserves of 11.5 billion tons, but the iron content is low at around 33%, which is significantly below the standard for high-grade ore [3] - Russia's iron ore reserves total 29 billion tons, with over 60% being high-quality ore, allowing for direct use in steel production [5] - China's iron ore reserves are 16.2 billion tons, but the iron content is also low at approximately 34%, necessitating additional processing [7] Group 2: Iron Ore Consumption and Production - The U.S. consumes about 120 million tons of iron ore annually but can only produce 40 million tons domestically, leading to a reliance on imports from allies like Canada and Brazil [3] - China has an annual iron ore consumption of over 130 million tons, with a production capacity of nearly 1 billion tons of raw ore, but still imports significant amounts from Australia and Russia [7][9] - The global iron ore production capacity is heavily dominated by Australia and Brazil, which together account for half of the total supply [7]
