In South Korea, the manufacturing system from chalcopyrite (CuFeS₂) to Cu products is divided into two parts: electrolytic Cu manufacturing and Cu product manufacturing (CPM). Most of the CPM waste is deposited in landfills unlike the waste generated in electrolytic Cu manufacturing that has a good recycling ability. Therefore, in this study, a method to improve the utilization of CPM waste was proposed as a case study for South Korea. Furthermore, the CPM was investigated and classified into five types in terms of the raw materials, major products, additives, main processes, and characteristics of the CPM waste (waste type, particle size, and chemical composition). Next, the CPM waste was environmentally assessed via leaching toxicity tests using the Korean standard official method, ES 06150. In addition, the amount of specific heavy metals (Pb, Cu, Cd, As, Hg, and Cr⁶⁺) was determined to confirm the presence of substances labeled as hazardous waste. Based on these results, a pretreatment method with grinding (under 0.1 mm), screening (0.15 mm grid), magnetic separation (1.0 T), and alkali leaching (30°C–90°C and 1–5 mol/dm³) was proposed. The final materials can be categorized into groups, such as fine-particle groups with high Zn and Fe contents, leachate groups with high Cu and Zn concentrations, and metal-scrap groups. Moreover, material flow analysis of all CPM waste streams in the designed pretreatment method was conducted in South Korea in 2019.

在韩国，黄铜矿（CuFeS ₂）将铜制品分为两部分：电解铜制造和铜制品制造（CPM）。与电解铜生产中产生的废物具有良好的回收能力不同，大多数CPM废物都沉积在垃圾填埋场中。因此，在本研究中，提出了一种提高CPM废物利用率的方法，作为韩国的案例研究。此外，对CPM进行了调查，并根据其原料，主要产品，添加剂，主要工艺和CPM废物的特性（废物类型，粒度和化学成分）将其分为五种类型。接下来，使用韩国标准官方方法ES 06150通过浸出毒性测试对CPM废物进行了环境评估。此外，特定重金属（Pb，Cu，Cd，As，Hg和Cr ⁶⁺已确定）以确认是否存在标记为危险废物的物质。根据这些结果，采用了研磨（0.1  mm以下），筛分（0.15  mm网格），磁选（1.0  T）和碱浸（30°C–90°C和1-5  mol / dm ³）的预处理方法。被提出。最终材料可以分为几类，例如具有高Zn和Fe含量的细颗粒组，具有高Cu和Zn浓度的渗滤液组和金属废料组。此外，2019年在韩国对采用设计的预处理方法的所有CPM废物流进行了物料流分析。
