Abstract: Acid mine drainage is recognized as a serious environmental issue at mine sites world wide. While sulphate and metal concentrations in acidic drainage can reach exceptionally high levels, these can also be elevated and of concern in neutral drainage from waste rock and tailings. “Neutral mine drainage” (NMD) has not yet received as widespread attention as acid mine drainage (AMD). The oxidation of sulphide minerals and the production of either acidic or neutral contaminated drainage is affected by many factors. This paper examines the specific factors that result in the production of “neutral mine drainage” from mine wastes. Several case studies are presented which involve predictive geochemical modelling to illustrate the possible time frame and magnitude of contaminated neutral drainage.

Abstract: The `ferrite process' is an excellent method for treating waste water containing iron and arsenic, but cannot be directly applied to mine drainage where silicon and aluminum ions are present, because they strongly inhibit ferrite formation. As a result of the development of related technologies such as the elimination of silicon, the concentration of iron, and the oxidation of ferrous ions using iron-oxidation bacteria, a new ferrite formation process has been developed and applied to the mine drainage of the Matsuo Mine. The paper discusses the application of the ferrite sludge to magnetic marking materials, magnetic fluid for metal separation and recovery, and the semiactive magnetic damper is described. The related technologies which will be expected to play an important role in solving the environmental problems are also described. These technologies will change the ferrite sludge to beneficial materials, which can be used for carbon dioxide decomposing catalysts, reuse of dry batteries, fish gathering blocks, and cement tracer for ground improvement
