Which separation method is used to separate metals ? Which are the separation methods used in agriculture ?

1. Liquation (metals)

Liquation is a metallurgical method for separating metals from an  ore or alloy. The material must be heated until one of the metals starts to melt and drain away from the other and can be collected.

2. Threshing and winnowing ( agriculture )

Wind winnowing is an agricultural method developed by ancient cultures for separating grain from chaff. It is also used to remove weevils or other pests from stored grain.

Threshing, the loosening of grain or seeds from the husks and straw, is the step in the chaff-removal process that comes before winnowing.

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary
