The number of crushing stages necessary to reduce ore to the proper size varies with the type of ore. Hard ores like gold, iron, and molybdenum ores, may require as much as a tertiary crushing. To design a good crushing plant one has to follow these three steps: crusher selection, crusher layout and process design. 2.4 Crushers

Underground mining methods mostly produce a feed that is finer than in a typical open pit mine, resulting in higher capacity through the plant. 3. Scalping. Scalping is usually recommended before a jaw crusher – gyratory crushers can handle excavated ore. Primary gyratory crushers are not as sensitive to fines.
