| Abstract |
The disposal of pollutants in mine drainage is difficult because they are diluted with so much water. Sale of extracted pollutants is not economical. Acid can be neutralized but sulfates are left in solution. Iron can be precipitated but the precipitate is one of the most difficult to dewater. Ultimate disposal of solids will be to the land, either in dumps or spread thinly on pasture or woodland. Brines too strong to be accepted in surface waters must go to permanent storage or to the ocean. The paper has reviewed available processes for dealing with mine drainage and points out difficulties and advantages associated with them. (Author) |
