1.Product Introduction Gold Ore Processing Equipment

This is a type of gravity separation equipment specifically designed to process fine-grained gold (typically between 30 microns and 2 mm). By simulating a sorting process involving natural water flow and vibration, it achieves high-efficiency separation of gold from gangue minerals.

2.Application Gold Ore Processing Equipment

This equipment is primarily used in the following scenarios:

• Gold Ore Beneficiation: It is the mainstream gravity equipment for processing coarse, medium, and fine-grained gold in placer and lode gold deposits, especially for "easy-to-process" ores where gold exists in its native metallic form.

• Other Metal Beneficiation: Equally suitable for separating other metal minerals with significant density differences, such as tungsten, tin, titanium, tantalum, copper, manganese, chromium, and zirconium.

• Pre-concentration & Scavenging: Frequently used as a pre-concentration device to preliminary enrich large volumes of low-grade ore, reducing the burden on downstream processes; or as a scavenging device to recover residual fine gold from tailings, improving total recovery rates.

• Small and Large-Scale Mining: Available in both laboratory and industrial models, it is suitable for small-scale/artisanal mining as well as gravity separation workshops in large-scale mines.

3.Working Principle  Gold Ore Processing Equipment

The working principle is based on mineral density differences and asymmetric reciprocating motion:

• Feeding: Ore pulp (a mixture of ore and water) is uniformly distributed onto an inclined deck surface featuring specialized grooves or riffles.

• Stratification: Under the combined action of the asymmetric reciprocating motion (driven by a crank-and-link mechanism) and transverse water flow, high-density gold particles (specific gravity $approx$ 19.3) settle to the bottom layer. They are pushed by the "snapping" motion of the deck and the water flow to move in a specific direction (usually laterally).

• Separation: Lower-density gangue minerals (specific gravity $approx$ 2.5–3.0) remain in the upper layer and are carried away by the water flow, discharging from the opposite side of the deck.

• Concentrate Output: After multiple stages of stratification and lateral movement, the high-density gold particles are enriched in a specific concentrate zone on the deck, forming high-grade "directly smeltable gold concentrate" collected via a dedicated concentrate trough.

4. Advantages  Gold Ore Processing Equipment

Compared to chemical beneficiation methods (such as cyanidation), the shaking table for directly smeltable gold concentrate offers these significant benefits:

• Environmentally Friendly: Requires no chemical reagents (such as cyanide), eliminating the environmental pollution risks associated with the use, storage, and disposal of toxic chemicals.

• Cost-Effective: Relative equipment investment and operating costs are low. With low energy consumption and simple maintenance, its operating costs are far below those of a cyanidation plant.

• Simple Process & Easy Operation: The equipment structure is straightforward and easy to operate, with low technical requirements for personnel.

• High-Grade Output: Efficiently produces concentrate with high gold grades and minimal impurities. This simplifies the overall process flow and reduces the complexity and cost of subsequent smelting.

• High Recovery Rate (for Coarse Gold): Offers very high recovery rates for larger particles of free gold.

• Safe and Reliable: Enhances production safety by avoiding the use of highly toxic chemicals.
