「城市矿山」资源化率突破60%｜多金属工业固废再生利用调查报告

Group 1 - The article emphasizes the high recycling value of industrial waste materials, including raw ores, slag, and mining powder, which contain valuable metal elements such as gold, silver, copper, lead, zinc, nickel, and tin [1][2] - Modern mineral processing technologies can extract valuable metals from slag and mining powder, which were previously considered waste, thus promoting resource reuse and reducing environmental impact [1][2] - The recycling of metal-containing materials not only lowers the cost of acquiring raw materials for companies but also minimizes environmental damage caused by new mining activities, aligning with sustainable development principles [2] Group 2 - Electronic waste, often referred to as "urban mines," contains precious metals like gold and copper, which can be extracted through specialized processing [2] - Chemical production waste may also contain essential metals such as nickel and tin, which are crucial for industries like stainless steel manufacturing and electronic welding [2] - Companies are encouraged to contact professional recycling organizations to ensure that these waste materials are properly processed, creating economic benefits while contributing to environmental protection [2]
