What do you mean by copper requirements?

Simply put, the grade of mineral resources refers to the proportion of mineral content in ore. The higher the proportion, the less impurities, the lower the smelting difficulty, the higher the smelting output and the more mining value.

Due to the requirements of industrialization, the whole set of smelting equipment is designed according to a certain taste of ore, that is to say, if the taste of ore can not reach the height required by the equipment, it can not be smelted, so the deposit with low taste is of no mining value, which is the taste requirement of the deposit.

The correlation is as follows

One of the metal mineral resources. Refers to the copper reserves, reserves base and resources. According to the annual assessment of world mineral resources, the world refined copper consumption in 2002 was 65,438+04,957,000 tons, of which construction accounted for 44%, electrical and electronic industries accounted for 25%, machinery manufacturing accounted for 65,438+00%, transportation equipment accounted for 65,438+065,438+0%, and daily consumption accounted for. In the same year, the world refined copper output was 6.5438+0.534 million tons, and 5.575 million tons of waste copper was recovered, accounting for 36.3% of the total refined copper output. The world copper production is 13525600 tons.

Supply exceeds demand in the world market. In 2003, the world's proven copper reserves were 470 million tons, including Chile1600,000 tons, the United States 35 million tons, Peru 35 million tons, Poland 31000,000 tons, Indonesia 28 million tons, Mexico 27 million tons, China 26 million tons and Russia 2 138.

The reserve base is 940 million tons (63 million tons in China, 360 million tons in Chile, 70 million tons in the United States, 60 million tons in Peru, 43 million tons in Australia, 38 million tons in Indonesia and 35 million tons in Zambia). There are more than 50 super-large copper mines in the world with copper reserves exceeding 5 million tons.
