Simply, in this context, screening involves separating particles of an ore ac- cording to size and, often, geometry. This is the primary reason why screening is performed. The screening process typically follows after comminution processes such as primary crushing and secondary crushing. There are different types of screens available.Simply, in this context, screening involves separating particles of an ore ac- cording to size and, often, geometry.

The main steps include crushing, screening, grinding, classification, separation ( gravity separation, flotation separation, and magnetic separation), water removing (concentration, filtration, and drying).I was an extractive metallurgist. Extractive metallurgy is 60 or 70 percent materials handling--crushing, grinding, conveying, pumping, handling materials. Almost anyplace I would go in any of these plants, I could find places that I could save the company a lot of money on the materials handling--like screening and crushing and so on.
