Abstract
Acid mine drainage (AMD) is one of the most important research subjects of mine environmental treatment and remediation. In recent years, quite a little scholars, at home and abroad, have studied the types, characteristics, formation sequence and assemblages of a majority of secondary mineral resources in acid mine drainage, and so on. And on this basis the secondary minerals, such as jarosite and schwertmannite, were experimentally tested, and the adsorption and passivation ability of several main secondary minerals to heavy metal ion was tested as well. In this paper, the types of secondary minerals found in the acid mine drainage which formed in different environments were summarized systematically and elaborately. In the past a dozen years, the formation sequence and assemblages of these secondary minerals were made a preliminary study. The formation conditions, chemical synthesis methods and conditions of jarosite and schwertmannite, Basaluminite, goethite, hematite, and other main secondary minerals which may have the application value were elaborately discussed and analyzed. And furthermore, the adsorption capacity and passivation of heavy metal ions was analyzed. In the end, the application prospects and application ways of these typical main secondary minerals in acid mine drainage were summed up.
