Scope

This standard specifies the processing requirements for producing crude copper powder from physically crushed waste circuit boards, and is applicable to such physical processing scenarios. It requires that the site be located far from residential areas, with a reasonable layout, and equipped with crushing machines, sorting machines, and other equipment. The operators must be trained and certified to work on the job, and the raw materials must be inspected and stored in accordance with the norms. After three-stage crushing, the materials are refined to 0.2-0.8mm, and then copper powder is separated from non-metals by air separation and electrostatic sorting. The finished products are divided into three grades, with copper content of ≥80%, 65%, and 50% respectively, and the powder and particles are evenly distributed. At the same time, it requires that the treatment of waste gas, wastewater, and solid waste, as well as noise control, meet the standards, and that a safety production system be established, with protective and explosion-proof facilities provided.
