Product Overview

The gold dredger is an integrated, all-in-one gold-mining device that combines excavation, conveying, screening, mineral processing, and tailings disposal into a single workflow. It requires no additional auxiliary equipment to complete the entire process—from material excavation to gold recovery and tailings discharge—making it specially designed for large-scale placer gold mining operations. The core of the equipment includes an excavation system, a screening system, a mineral-processing system, and a tailings-disposal system. Its processing capacity and excavation depth can be flexibly adjusted according to the model: small units can handle 100–400 cubic meters of material per day, while large industrial-grade dredgers can process 2,000–5,000 cubic meters daily; excavation depths typically range from 1 to 25 meters, adapting to various water bodies and ore vein conditions. The equipment boasts both environmental benefits and intelligent features, integrating a PLC automatic control system and a recirculating water system. Not only does it efficiently recover gold, but it also simultaneously recovers high-value minerals such as tin, tungsten, and ilmenite, maximizing resource utilization and precisely meeting the large-scale production needs of mining companies, engineering contractors, and overseas investment enterprises, thereby thoroughly addressing the pain points of traditional gold-mining processes—namely, incomplete workflows and poor equipment compatibility.

Working Principle

1. The excavation system starts up, adjusting the excavation depth (1–25 meters) according to operational requirements, precisely excavating gold-bearing materials from riverbeds and placer deposits without manual assistance, thus achieving automated excavation;

2. After excavation, the material is conveyed at a steady pace by the transport system to the screening system, where large impurities and gravel are removed, leaving behind gold-bearing ore that meets the criteria for mineral processing, thereby enhancing subsequent processing efficiency;

3. The screened gold-bearing ore enters the mineral-processing system, where gravity separation and other core technologies efficiently separate gold while simultaneously recovering high-value minerals such as tin, tungsten, and ilmenite, enabling diversified resource recovery;

4. The processed tailings are discharged in compliance with regulations via the tailings-disposal system, which works in tandem with the recirculating water system to achieve water recycling, embodying environmentally friendly operational principles. The entire process is managed by a PLC automatic control system, allowing precise adjustment of parameters at each stage to ensure operational stability and recovery rates, realizing fully integrated, intelligent operation throughout the workflow.
