Gold ore processing plant

Step 1: Crushing
Due to the raw ore size is large, it is necessary to be crushed into suitable particles. The loader sends raw ore into vibrating feeder, which feed material evenly to jaw crusher for primary crushing process. In ore benefication plant, one important rule is to crush more and grind less. If nessary, cone crusher or hammer crusher could added as second crushing process to get suitable particles.
Machine list: hopper, vibrating feeder, jaw crusher, cone crusher or hammer crusher(optional)

Step 2:Grinding
After crushing, the material goes into ball mill via feeder for fine size, such as 325mesh. Ball mill and spiral classifier is a closed-loop circle. The material after ball mill grinding comes into classifier for classification. Qualified fine ore into next process and unqualified coarse ore return back to ball mill for grinding again. In this grinding process, we must first make clear the requirements for each ore particle standards.
Machine list: electromagnetic vibrating feeder or similar, ball mill, sprial classifier

Step 3: Selecting
In the production process,not all the ore powder are in line with the standard.The usful ore powder needs to be selected via professional equipment, such as mixing tank, flotation machine, shaking table, spiral chute etc. Then the qualified concentrate powder from ore is stocked in settling pond.
Machine list: mixing tank, flotation machine, magnetic separator, centrifugal gold machine, shaking table etc.

Remarks: Due to various constraints, there are always some residual moisture in the ore powder, concentrate dehydration process could be added. This step could meet the requirements of transportation and smelting etc.
The machines, such as box pressure filter, rotary dryer etc is optional.
