Non-ferrous metals industry achieved remarkable results in energy saving

  In 2010, China's 10 kinds of common non-ferrous metal production reached 31.35 million tons, ranking first in the world for eight consecutive years. Production of 30 million tons of alumina, aluminum 16 million tons, accounting for 38% of world production and 40%. Copper was consuming more than 3 million tons of aluminum consumption exceeds 500 million tons. Non-ferrous metal industry is energy-intensive industries, energy saving heavy task. 
With advances in technology, in support of national authorities and their own efforts, non-ferrous metals industry technology and equipment levels were significantly increased, some of the equipment has reached the world advanced level. Advanced flash smelting, oxygen-enriched bath smelting, hydrometallurgy technology, copper, nickel, zinc smelting dominant; innovation of the "oxygen bottom-blowing - a new lead smelting blast furnace reduction process" is to promote the application; with intellectual property rights of a mineral diaspore Bayer, high-grade ore to strengthen the sintering technology, sandy alumina production technology and other successful applications, greatly improving the technological level of China's alumina production. 350 kA, 400 kA and other large aluminum tank into use, the energy consumption of China's electrolytic aluminum greatly reduced. 
In 2010, integrated AC power consumption of aluminum ingot 13,979 kwh / ton, the "Eleventh Five-Year" early fall 718 kwh / ton; alumina overall energy consumption of 632.4 kilograms of standard coal / ton, the "Eleventh Five-Year" early fall 21.2%; overall energy consumption for the smelting of copper 360.3 kilograms of standard coal / ton, the "Eleventh Five-Year" initial down 39.4%; lead smelting comprehensive energy consumption for the 453.5 kilograms of standard coal / ton, the "Eleventh Five-Year" early fall 16.4% ; overall energy consumption of electrolytic zinc 946.6 kilograms of standard coal / ton, than the "Eleventh Five-Year" initially decreased by 24.1%. Remarkable energy saving.
