Answer:
Filtration
Step-by-step explanation:
Filtration is a separation technique used in the laboratories to separate two elements or compounds by using a filter paper and a beaker.
Drierite is also know as calcium sulphate and silicon is made up of silica.
The filtration equipment are taken to separate these two components. The separation method is used in the second beaker by pouring the mixture through a filtering funnel and using a filter paper. The solid remaining of silicon remains on the filter paper separating the two.
