Research Progress on Comprehensive Utilization of Iron Ore Barren Rock

With the continuous exploitation of China's iron ore resources, it is inevitable to produce a large number of waste rocks. As the concept of a green mine is deeply rooted in the hearts of the people, the treatment and utilization of these iron ore waste rocks have always been a hot and difficult issue for mining enterprises. At present, the treatment methods for waste rock in iron ore mainly include goaf backfilling, engineering application, recovery of iron ore and preparation of sand and gravel aggregate. Based on the introduction of the basic situation of iron ore waste resources in China, this paper summarized the research progress of comprehensive utilization of iron ore waste resources in China and other countries in recent years, in order to provide a reference for solving the problem of waste rock storage in China in the future.
