China should develop a more efficient copper recycling system to ease the demand for limited copper supplies. In 2018, the Chinese secondary copper production capacity exceeded 4 million tons, but due to a shortage of raw materials, the output was only 3.25 million tons (Yangtze non ferrous metal network, 2019). The lack of scrap …

Global copper slag (CS) emissions reached 57.2 million tons in 2021. Despite the increasing reuse of CS, the treatment of CS is still dominated by landfill so far, which not only occupies land resources but also causes damage to the environment. The application of CS to cement-based materials (CBMs) is one of the main approaches to its …

The copper slag in this research was sampled from Yunnan Province, China. According to the results in Table 1 and Fig. 1 (b), the copper slag included 40.12 wt% Fe, 29.05 wt% SiO 2, and 8.59 wt% (CaO+ MgO) and was primarily composed of the Fe 2 SiO 4 and Fe 3 O 4 phases. It also contained 0.61 wt% Cu, 0.21 wt% Pb, and 0.58 wt% Zn, …

is Asia, the continent with the largest production of copper slag in the world through producing 7.26 million tons of copper slag per annum [22,23]. Therefore, there is a need for utilization of this generated copper slag. North America, Europe, South America, Africa and Oceania produced 5.90, 5.56, 4.18, 1.23 and 0.45 million tons of copper ...
