Project Background and Engineering Overview

This project is located in the renowned placer gold mining area of Mozambique, Africa, and is one of the largest mineral resource development projects in the region. The mining area features complex geological conditions, with ore layers characterized by extremely high mud content, significant gravel content, and clay minerals that readily encapsulate gold particles, making it difficult to effectively separate valuable minerals from gangue. Prior to introducing Yake equipment, the client relied on traditional beneficiation equipment, which not only suffered from low processing efficiency and failed to meet the production capacity requirements of large-scale mining but also exhibited unstable recovery rates, leading to severe resource wastage and persistently high operating costs. Consequently, achieving efficient, stable, and cost-effective mineral processing under such challenging conditions became a critical technical challenge for the project.

To thoroughly address this issue, the Yake technical team conducted extensive on-site investigations at the mining area, performing specialized analyses tailored to the characteristics of high-mud, gravel-rich ores. Ultimately, they customized a large-scale, integrated mineral processing solution for the client. At the heart of the project is a large-scale beneficiation vessel with a processing capacity of 1400 cubic meters. This vessel integrates multiple core technologies, combining trommel screening, hydraulic washing, and gravity separation systems into a unified design, forming a complete process flow—from raw material feeding, desliming and screening, washing, to heavy media separation and recovery.

During operation, the ore first undergoes grading through an efficient trommel screen, effectively separating coarse gravel from fine mineral particles. It then enters a specially designed hydraulic washing unit, where powerful water jets and mechanical agitation fully disintegrate cohesive ore masses, completely removing clay coatings adhering to gold particles—thus resolving the long-standing technical challenge of “gold particle encapsulation.” Finally, an optimized gravity separation system precisely sorts minerals based on their specific gravities, ensuring highly efficient gold recovery. The entire system boasts a high degree of automation, smooth operation, and seamless integration between each stage, delivering truly “efficient, intelligent, and continuous” processing.

Project Implementation Timeline

The project was meticulously managed throughout its lifecycle, from conceptual design and equipment manufacturing to on-site installation and commissioning, with strict quality control and adherence to timelines. Leveraging a mature technological framework and efficient engineering execution capabilities, the equipment was successfully delivered and put into operation. Since formal commissioning, the system has demonstrated stable and reliable performance, with all key performance indicators meeting design specifications and enduring prolonged testing under complex field conditions.

Application Outcomes and Benefit Analysis

The deployment of the Yake-customized beneficiation vessel has brought revolutionary improvements to the client’s production processes, fully achieving the project’s intended objectives:

1. A qualitative leap in processing capacity: The equipment consistently processes 3,000–3,500 tons of ore per day, far exceeding the client’s initial expectations and significantly expanding the mine’s overall extraction scale and operational efficiency.

2. Significant optimization of recovery metrics: The overall recovery rate has increased to over 92%, with stable concentrate grades, minimizing metal losses and achieving industry-leading resource utilization levels.

3. Substantial reduction in operating costs: Through systematic design optimizations, energy consumption per unit has decreased by approximately 18%, enabling expanded production while effectively controlling energy usage and reducing unit production costs.

4. Drastically shortened investment payback period: With efficient output and excellent cost control, the project’s investment payback period has been reduced to just 8–10 months, realizing rapid capital return and profitability, thereby highlighting its strong investment value.

Customer Feedback

The successful implementation of the project has earned high praise and unanimous acclaim from the client. The client emphasized that Yake’s equipment not only features advanced technology and reliable performance but also precisely addresses real-world challenges on-site, truly delivering “customized solutions with outstanding practical results.” Following the equipment’s commissioning, mining productivity has improved markedly, significantly enhancing the company’s competitive edge, and a solid partnership has been established between both parties. The client looks forward to further deepening cooperation with Yake in the future, jointly exploring innovative technologies and applications across additional mineral development fields.
