What are the main methods of mining? | American .

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

Mechanical screening - Wikipedia

Mechanical screening - Wikipedia

Mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size.. This practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling. [A method of separating solid particles according to size alone is called screening]
