1. Crushing stage:
The mined ore is usually large and needs to be broken into smaller particles by a crusher. Primary crushing usually uses equipment such as jaw crushers and gyratory crushers to crush the rock gold ore to coarser particle size; cone crushers, impact crushers, etc., are used for further fine crushing.
2. Grinding and classification:
It is mainly used to grind the crushed ore further to a particle size suitable for subsequent mineral processing. The grinding process is usually carried out using equipment such as ball mills, rod mills, wet mills, spiral classifiers, etc. Classification aims to separate the fine particles that have been ground from the coarse particles that have not been ground, ensuring that the grinding product reaches the required particle size distribution.
