copper tailings

copper tailings Wires and Scraps - Alibaba

copper tailings come in the form of pre-made wires that are ready to use. Others come in sheets that can easily be cut down to the ideal size for your needs. Certain brands sell scrap products that are suitable for recycling and can be repurposed to save costs and prevent waste. Most feature very high levels of purity to ensure quality results.
