Gold mining as a global important mineral resources development field. The efficiency of gold ore crushing process directly affects the economic benefits of the mine and the level of environmental protection.  With the continuous iteration and upgrading of crushing equipment, but in the face of the characteristics of gold ore such as high hardness, fine embedded particle size, high mud content . We should choose the equipment scientifically and configure the gold ore crushing line reasonably.

The following is a comprehensive programme design of gold ore crushing equipment, combining process flow, equipment selection and innovative technology application, applicable to different scale and characteristics of gold ore crushing needs:

Core crushing equipment selection

Coarse Crushing Stage

Jaw crusher

Jaw crusher: preferred as primary crushing, handling large ore (maximum feed size ≤1500mm).  With compressive strength up to 320MPa, featuring simple structure and low maintenance cost.

Middle and fine crushing stage

Impact crusher

Impact crusher: suitable for medium hardness ores. But need to pay attention to the wear and tear caused by high hardness ores.

Fine crushing and grinding

Roll Crusher

Roll Crusher: Discharge size can be adjusted to millimetre level, which is suitable for gold ore crusher and can reduce production energy consumption.Discharge size can be adjusted to millimetre level, suitable for small and medium-sized processing plants, reducing energy consumption.

High-pressure roller mill

High-pressure roller mill: grinding materials to 0-5mm, reducing the grinding load, in line with the principle of ‘more crushing and less grinding’.

Auxiliary equipment

Vibrating screen: high frequency fine screen to achieve accurate classification, reduce the amount of returned material.

Crushing Process

Flow: Jaw Crusher (coarse crushing) → Impact Crusher (medium crushing) → Roll Crusher (fine crushing) → High Pressure Roller Mill (grinding), simplifying the crushing process.

The selection of gold ore crushing equipment is by no means a simple stack, but requires comprehensive consideration of geological conditions, product demand, capital investment and other multi-dimensional factors. It is recommended that users conduct laboratory tests to clarify the dissociation characteristics of the ore before purchasing, and combine with the simulation analysis of professional engineers to customise a ‘one-mineral-one-policy’ solution.
