Gold ore processing plant

Process Introduction

With the rising gold prices in recent years, the rapid development of the gold industry has been further stimulated. With the reduction of high-grade gold reserves, gold ore gold beneficiation process has gradually become the mainstream trend of global gold beneficiation. The content of gold in gold ore is very low, gold beneficiation process must be crushing, grinding and sorting of ore, gravity separation and flotation are more widely used. Gravity separation plays a very important role in alluvial gold production. Flotation is a widely used beneficiation method in rock and gold ores.

Gold ore processing plant workflow

Step 1:Crushing

The loader feeds the raw ore into the vibrating feeder, and the vibrating feeder feeds the material evenly into the jaw crusher for the preliminary crushing process. If necessary, cone crusher or hammer crusher can be added as a second crushing process to obtain suitable particles.
Required equipment; vibrating feeder, jaw crusher, cone crusher or hammer crusher

Step 2:Grinding

The crushed material passes through the vibrating screen into the ball mill, through the mill for fine treatment
Required equipment: ball mill, sprial classifier

Step 3:Separation

Gold ore gravity separation: gravity separation process is to rely on the medium fluid and a variety of mechanical force of the combined effect, through the creation of suitable loose layer and separation conditions, to obtain different density and size of the particles. The method is only applicable to single dissociated gold ore.
Gold Ore Flotation: The slurry is fed into the flotation machine, and the chemicals are added and stirred thoroughly to select the useful ore powder. Aerated by stirring, so that the mineral particles selectively fixed in the air bubbles; floating to the surface of the slurry is scraped out to form a foam product, the rest of the slurry is retained in the slurry, in order to achieve the purpose of separating the minerals
Required equipment: flotation machine, magnetic separator, shaking table

Step 4: Drying

the obtained gold powder is fed into the desiccant for drying to get the required material.

The selection and combination of these equipments depends on the nature of gold ore, beneficiation process and production scale and other factors. In practical application, the selection and configuration of equipment are usually carried out according to the specific situation to achieve the best beneficiation effect and economic benefits.
