Name the method of sedimentation is used for the separation of this type of mixture

Answer 1

Answer:

Threshing: Threshing is used for separating seeds from the harvested stalks.

Manual Threshing: When the quantity is small, threshing is done manually. Small bundles of the harvested stalks are thrashed on a hard surface. This helps in separating the grains.

Threshing by Animals: For larger quantities, threshing is done in the traditional way; by using animals. For this, stalks are spread around a pole. Several bullocks are tied to the pole and are made to walk over the harvested stalks. Trampling by hooves of the animals helps in separating grains.

Threshing Machine: Now-a-days, threshing machines are used for the purpose. It can be powered by either a diesel engine or an electric motor. It helps in saving time and labour.
