Product Overview

The gold selection integrated machine is a complete set of gold selection equipment that integrates gravity separation, centrifugal concentration and other processes. It features a high degree of automation and stable recovery rates. Its functions are similar to those of the gold panning integrated machine, but it places greater emphasis on the completeness and refinement of mineral separation. It is specially designed for large-scale, refined gold selection scenarios, precisely meeting the core needs of ore dressing plants, mining companies, and resource comprehensive utilization enterprises. The equipment covers the entire process flow, including crushing, grinding, classification, separation, and dewatering, eliminating the need to pair it with separate devices, thus achieving one-stop refined operations from raw ore processing to concentrate production. Its technical principles integrate various processes such as gravity separation, magnetic separation, and flotation (which can be flexibly configured according to mineral properties), with gravity separation remaining at its core. By leveraging differences in mineral specific gravity, shape, and friction coefficient, it achieves efficient separation. Equipped with optimized flow channels and a power system, it ensures materials maintain optimal motion states throughout different operational stages, maximizing metal recovery rates, with concentrate grades reaching over 80 g/t. The equipment also boasts energy-saving and environmentally friendly advantages, keeping unit tonne ore energy consumption within 1.5 kWh, complying with domestic and international environmental standards. It effectively addresses pain points associated with traditional gold selection processes—such as numerous steps, complex operations, high energy consumption, and non-compliance with environmental regulations—helping enterprises achieve both resource comprehensive utilization and enhanced overall benefits. It is suitable for various scenarios, including hard rock gold mining, placer gold mining, polymetallic ore mining, and tailings resource reutilization.

Working Principle

1. After raw ore enters the equipment, it first passes through the crushing module to reduce large ore chunks to ≤10 mm particle size, then proceeds to the grinding module for further milling, fully exposing gold particles and laying the groundwork for subsequent refined separation, catering to the processing needs of complex ores such as hard rock gold and polymetallic ores.

2. The ground material then enters the classification module, where specialized equipment screens out ore meeting separation requirements while removing impurities and substandard particles, preventing contamination from affecting separation accuracy and improving subsequent separation efficiency.

3. Following classification, the ore moves into the separation module, integrating gravity separation and centrifugal concentration as core processes. Depending on mineral characteristics, magnetic separation or flotation may also be incorporated: gravity separation leverages differences in mineral specific gravity for preliminary separation, while centrifugal concentration uses adjustable speeds of 300–800 r/min to generate centrifugal force fields, enhancing capture of fine gold particles (0.01–0.1 mm) and further boosting separation precision and recovery rates. During this process, multiple valuable associated minerals can also be recovered simultaneously.

4. The separated concentrate then enters the dewatering module for dehydration treatment, yielding high-grade concentrate. Tailings can be further processed through auxiliary systems for secondary recovery, maximizing resource utilization. The entire process is managed by an automated control system, requiring minimal manual intervention and enabling continuous, stable production.

5. The equipment incorporates an internal water circulation system, allowing wastewater to be settled and reused, while maintaining tailings moisture content below 15%. This approach is energy-efficient and environmentally friendly, compliant with international environmental standards such as EU RoHS and US EPA, thereby avoiding compliance risks.
