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 |

Abstract |
A simulation model is developed of the efficiency and economics of an application of ecotechnology – using a created wetland to receive and treat coal mine drainage. The model examines the role of loading rates of iron on treatment efficiencies and the economic costs of wetland versus conventional treatment of mine drainage. It is calibrated with data from an Ohio wetland site and verified from multi-site data from Tennessee and Alabama. The model predicts that iron removal is closely tied to loading rates and that the cost of wetland treatment is less than that of conventional for iron loading rates of approximately 20-25 g Fe m “SUP -2” day “SUP -1” and removal efficiencies less than 85%. A wetland to achieve these conditions would cost approximately US$50 000 per year according to the model. When higher loading rates exist and higher efficiencies are needed, wetland systems are more costly than conventional treatment. -Authors |

Abstract |
One of the serious problem faced by the mining industry is the disposal of acid mine drainage in view of it's harmful effects on receiving water bodies.Studies were conducted at Churcha underground mines of Colleries of South Eastern Coal Fields (CoalIndia Ltd) on the acidic mine waters with a view to evolve effective treatment system. The results of treatability studies alongwith viable treatment options are discussed in the paper. |
