Abstract: Focusing on environmental issues caused by gold mining and ecological restoration technology,this study analyzes the severe environmental impacts of gold mining,emphasizing the necessity of ecological restoration.Pollution statuses and composite pollution as well as its treatment challenges at various stages of gold mining are detailed.Based on the cases of ecological restoration projects in several gold mines,the study made an in-depth analysis of the stopes,heap leaching sites,and tailings ponds,highlighting the environmental issues and restoration technologies.Prospects of ecological restoration of gold mines emphasize multidisciplinary integration,enhanced research quality,and integration of modern technology with scientific management.The importance of technological innovation and comprehensive application of restoration technology is stressed to achieve high-quality development of gold mines and a win-win scenario for the economy and the environment.
