Product Overview

The gold dredger is an integrated, all-in-one gold mining equipment that combines excavation, conveying, screening, mineral processing, and tailings disposal into a single system. It requires no additional auxiliary equipment to complete the entire process—from material excavation to gold recovery and tailings discharge—specifically 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 protection and intelligent advantages, integrating a PLC automatic control system and a circulating 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 completely resolving the pain points of traditional gold mining processes—such as 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 to precisely excavate gold-bearing materials from riverbeds or placer deposits without manual assistance, achieving automated excavation operations;

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

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

4. The processed tailings are discharged in a standardized manner through the tailings disposal system, paired with a circulating 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 and intelligent operation throughout the workflow.
