Description
Various types of copper-containing waste applicable to this process include scrap copper pipes, rods, wires, and recycled copper obtained from dismantling. Copper waste with high impurity content, such as smelting slag, is not suitable for this process. The smelting process primarily uses electricity and natural gas as energy sources, while charcoal is mainly used as an oxygen barrier agent. The project's water consumption mainly consists of make-up water for recirculating cooling; wastewater is not discharged externally. Domestic water and irrigation water are not included in this dataset. The exhaust gases generated during production originate from melting furnace and casting emissions, primarily consisting of particulate matter, sulfur dioxide, and nitrogen oxides, which are released into the atmosphere after treatment. The waste materials generated during the production process mainly include waste wire sheathing, plastics, etc., which are centrally collected and sold off for disposal; scrap edges are collected and reused by remelting; the slag mainly consists of metal impurities and cuprous oxide, classified as general industrial waste, and is collected for comprehensive utilization as building materials.
Activity Description
This dataset represents the process of producing recycled copper through high-temperature smelting of waste copper materials. It includes the energy and auxiliary materials input, as well as the emissions of air pollutants and generation of solid waste in the recycled copper production process.
