各种铜基合金废料,是生产铜合金和金属铜的主要原料之一。随着我国工业建设和工业技术的迅速发展,对各类铜合金的需要量必然将逐年增多,所以今后我国再生铜的产量,将会大大地增加。美国1936年炼得再生铜(利用含铜废料生产铜合金或金属铜称为再生铜)440,500吨,为从矿石生产铜合金和金属铜的81％;波兰再生铜的产量占铜产量的40～50％。我局各杂铜冶炼厂都是以各种铜基合金废料做为原料生产电解铜;而苏联、波兰及其他国家,大部分的铜基合金废料都是用来直接生产铜某合金,只有一小部分和杂质较高的杂铜才用来生产电解铜。因此与其他国家相比,我国生产再生铜的方法是极不合理和不经济的,主要缺点是:①杂钢废料
A variety of copper-based alloy scrap, is the production of copper and copper metal one of the main raw materials. With the rapid development of industrial construction and industrial technology in our country, the demand for various types of copper alloys is bound to increase year by year, so the output of recycled copper in our country will increase greatly in the future. United States 440,500 tonnes of reclaimed copper (copper copper or copper produced from copper-containing scrap, known as recycled copper) was produced in 1936 to produce 81% of the copper alloy and metallic copper from the ore; Poland’s recycled copper production accounted for 40% 50%. All of our copper smelters use copper-based alloy scrap as raw material to produce electrolytic copper. In the Soviet Union, Poland and other countries, most of the copper-based alloy scrap is used to directly produce copper alloy, only one A small portion of the impurities and the higher copper used to produce electrolytic copper. Therefore, compared with other countries, China’s method of producing recycled copper is extremely unreasonable and uneconomical, the main drawbacks are: ① miscellaneous steel scrap
