Up to date, the greater part of precipitates formed during the neutralization of mine drainage has been discharged into tailing dams. This fact is causing a serious problem concerning the life of dam, by the reason of that the precipitate is very voluminous and requires considerable space.
Accordingly, it can be said that the most effective solution for above-mentioned problem is to accelerate the utilization of precipitate.
In order to offer a technical information to various trials concerned with utilization of the precipitate, in the present paper, this research committee has reviewed about the following subjects of the material.
1) Physical and chemical properties.
2) Properties related to mineral processing such as handling property, fl oatability and property of agglomeration in water.
3) Practical examples of utilization and usability.
