Preparation process before separation
Including copper ore crushing, screening, grinding, grading and
other processes. The purpose of this process is to separate useful
minerals from gangue mineral monomers, and to dissociate various
useful minerals from each other.
1. Crushing process
The copper ore that needs to be processed must first go through the
crushing process. The vibrating feeder is fed through the silo, and
the vibrating feeder is evenly sent to the jaw crusher for primary
crushing, and the large raw ore is broken into small pieces of ore.
After the coarse crushed copper ore is screened, it is sent to the
cone crusher by the belt conveyor for
intermediate crushing and fine crushing, and the ore is broken into
smaller ore particles.
2. Grinding process
The copper ore processed into granules is screened by a vibrating
sieve and sent to a ball mill for grinding and crushing. Here also
need to use an auxiliary equipment – classifier. It can classify
and screen copper ore and release copper ore powder that meets the
requirements.
3. Screening and classification
According to the size of the sieve surface, the material is divided
into different particle size grades, which is often used to process
materials with coarser particle size. According to the different
settling speeds of particles in the medium (usually water), the
materials are divided into different equal-fall grades, called
classification, which is used for materials with smaller particle
sizes. Screening and grading are to separate the materials with
suitable particle size during the crushing process, or to divide
the materials into different particle size grades and select them
separately.
4. Ore washing process:
Ore washing is required to prevent the mud in the mud-containing
mineral raw materials from clogging the
crushing and screening equipment. If the raw materials contain
soluble useful or harmful components, they should also be washed.
Washing can be done as well as in screening and grading equipment.
