Commonly used gold mining equipment gold ore processing plant process

Stage 1: Crushing + Screening Process  

1. Gold ore crushing equipment (jaw crusher / cone crusher): crushing large ore into smaller particles, so that the particle size of the ore reaches 25mm or less, which is convenient for subsequent processing.

2. Classifier(Vibrating Screen / Trommel Screen): Screens and classifies the ore slurry after milling, classifying it into particles of different sizes.

Stage 2: Grinding Process 

3. Ball Mill: Used for further fine grinding of the ore to powder, according to the need to grind the ore size to 74μm (-200 mesh) 50% ~ 80% of the best, in order to subsequent beneficiation operations.

Stage 3: Beneficiation Process

4. Jig & Shaking Table: Used to carry out reclassification operations on ores to achieve separation and beneficiation based on the difference in particle densities.

5. Flotation Machine: Separation and beneficiation of minerals is achieved through the attachment of air bubbles to specific mineral particles in suspension.

6. Magnetic Separator: Using the magnetic difference of minerals in the ore, the ore containing magnetic minerals are sorted and extracted.

Stage 4: Concentrating process

7. Concentrator and dryer: using the gravity of solid particles, concentrator precipitates gold concentrate, separating the solid from the liquid, and then using the dryer to dry it, finally achieving a water content of ≤ 20%.

Main Gold Ore Beneficiation Processing Methods and Equipment.

一，Flotation gold ore processing

The flotation method is a widely used beneficiation method in rock gold mines. 80% of rock gold mines use this method for gold beneficiation, with recovery rates as high as 90-97%, and the gold concentrate selected can be sent to smelters for smelting.

Main equipment: jaw crusher, vibrating screen, ball mill, spiral classifiel, flotation machine, etc.

二, Gravity separation gold ore processing

Gravity Separation Gravity gold separation is based on the density of gold ore, widely used in alluvial gold mining, placer gold mining, hard rock gold mining, with small investment, large processing capacity, simper operation and high effiency.

Main equipment: jaw crusher, vibrating screen, ball mill, trommel screen, shaking table, jig, spiral chute, etc.
