At this flow each pond will have a detention time of 24 hours and will each contain 2,050 tons of limestone, inches in depth of organic compost consisting of mushroom compost and wood chips, and a ponded water layer of 4 ft. The ponds will discharge into a settling pond that will be 100' x 24' x 10'.
More than 5 X 106 tons of solid waste are produced annually from the processing of bauxite and approximately 90 X 106 tons have been accumulated in settling ponds . Red muds comprise about 90% of this tonnage.
The fly ash pond was created by construction of a 40m high earthen dam in an existing stream valley and then sluicing of fly ash into the pond. Appr oximately 40 hectares (100 acres) of the fly ash was covered with a 3 m layer of sands tone and shale blastro ck. The remaining area is open water up to 10 m deep.
Results indicate that the mixture of tailings sand and clay mix could be dewatered to 50% solids or more in minutes. The solids content of the mixture of overburden, sand, and clay discharged from the pilot plant averaged 67% solids. A sample of the mixture placed in .

Sediment control during construction includes ditching, silt fencing and construction of temporary settling ponds to reduce the temporary loads of sediment associated with the movement of large volumes of material. These measures will be temporary during the construction period, and may be decommissioned once construction is complete.
mine closure sta e. Our Mining operation is restricted above the ground water table. Now the lowest working depth of our existing mine pit is around m RL, whereas the presence of ground water table has been estimated to be around 100150 m RL. Therefore, there is no probability of any GW Intersection or exploitation of GW there .

were washed and pumped into settling ponds. The production of hydrogen fluoride began in 1956 with fluorspar as the raw material. An estimated amount of 400,000 metric tons of gypsum wastes were produced until 1982 in this process. These wastes were pumped along with alum muds into settling ponds on the island.

(BCC 2001). Sedimentation basins are stormwater detention systems that promote settling of sediments through the reduction of flow velocities and temporary detention. Key elements include purpose designed inlet and outlet structures, settling pond, and high flow, overflow structures.
31. Settling Pond. A manmade enclosure or natural impoundment structure constructed and used for the purpose of treating mine process water and/or runoff water from adjacent disturbed areas by the removal or settling of sediment particles. Several types of settling ponds or a series of smaller ponds may be used in water management.
