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 specifically 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, including crushing, grinding, classification, separation, and dewatering, eliminating the need for additional scattered equipment and enabling 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 the core technology. By leveraging differences in mineral specific gravity, shape, and friction coefficient, it achieves efficient separation. Equipped with optimized flow channels and power systems, it ensures optimal material movement 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 below 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 the raw ore enters the equipment, it first passes through the crushing module, where large pieces are broken down to ≤10 mm particle size. Then, it proceeds to the grinding module for further milling, ensuring that gold particles are fully exposed and laying the groundwork for subsequent refined separation, making it suitable for handling complex ores such as hard rock gold and polymetallic ores.

2. The ground material then enters the classification module, where specialized equipment screens out materials meeting separation requirements while removing impurities and substandard particles, thus preventing impurities from compromising separation accuracy and enhancing subsequent separation efficiency.

3. Following classification, the material moves into the separation module, which combines gravity separation and centrifugal concentration as its core technologies. Depending on mineral properties, magnetic separation or flotation processes can also be optionally incorporated: gravity separation leverages differences in mineral specific gravity for initial separation, while centrifugal concentration uses adjustable speeds of 300–800 r/min to generate centrifugal force fields, thereby strengthening the capture of fine gold particles (0.01–0.1 mm) and further improving 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, producing high-grade concentrates. Tailings can be further processed through supporting 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 is equipped with an internal water circulation system, allowing wastewater to be settled and reused. Tailings moisture content is maintained below 15%, ensuring energy efficiency and environmental compliance, meeting international environmental standards such as EU RoHS and US EPA, thereby avoiding risks of regulatory violations.
