The copper slag used in this study was obtained from China Minmetals Corporation. The copper slag was first crushed and ground into −200 mesh powder before the experiment. XRF-1800 X-ray Fluorescence spectrometry (XRF) (Shimadzu, Japan) was used for chemical analysis of the sample, and the result is shown in Table 1.

ample, hot stage processing of slags for materials as well as heat recovery techniques has been widely applied in steel plants with good results. However, increasing the utilization ratio of basic oxygen furnace slags remains a major challenge. Technological innovations in slag recycling are crucial for the steel industries in Japan and China.

Abstract. Steel slag is the main waste product in the steelmaking process. Because of its chemical composition and technical properties, it can be reused as raw material in steel plants and can serve as a substitute for aggregates in civil engineering. In this paper, we reviewed steel slag treatment, recycling, and management in China.

Of the approximately 5.6 Mta of steelworks slags, 36 % were recovered in 2017 and 23 % were recycled within the steel industry. The recovered quantities went almost entirely to road construction. Unfortunately, the Steel Institute has no information on the number of granulation plants for blast furnace slag in Brazil.

Newswise — Copper smelting is a major source of copper production, generating significant amounts of slag. In 2022, China produced over 11,000 kilotons of refined copper, leading to 2.2 to 3 ...

A sustainable waste utilisation, including metallurgical recycling and refined cleaning of the copper slag is considered a more preferred option than dumping or disposing it untreated in view of its potential economic and environmental benefits. The authors, in this study, have reviewed the generation mechanism, chemical/physical.

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 …
