Answer:
Electrostatic Separation would be best for this occasion.
Step-by-step explanation:
While limestone is a crucial component of many products and services, it has to meet a certain grade quality in order to be used in the creation of these products. When mining, limestone is taken from underground quarries and loaded into trucks to be transported to a processing plant. These deposits are then processed to increase the content (increasing the grade of limestone) while reducing the gangue (unusable substances) in ore minerals. This process is known as electrostatic separation.
