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 geological conditions at the mine site are complex, with ore layers characterized by extremely high mud content and a large proportion of gravel. Clay minerals readily encapsulate gold particles, making it difficult to effectively separate valuable minerals from gangue. Prior to the introduction of 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 operations but also exhibited significant fluctuations and poor stability in recovery rates, resulting in severe resource wastage and persistently high operating costs. Consequently, achieving efficient, stable, and cost-effective mineral processing under such complex ore conditions has become a critical technical challenge that urgently needs to be addressed.

To thoroughly resolve this issue, the Yake technical team conducted an in-depth field survey of the mining area, performing specialized analyses tailored to the characteristics of ores with high mud content and abundant gravel. 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, thereby 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 a highly efficient trommel screen, effectively separating coarse gravel from fine mineral particles. Subsequently, it enters a specially designed hydraulic washing unit, where powerful water jets and mechanical agitation work together to break up agglomerated mineral masses and completely remove clay coatings adhering to gold particles, thus solving the long-standing technical problem of “gold particle encapsulation.” Finally, an optimized gravity separation system precisely sorts minerals based on their specific gravities, ensuring efficient recovery of gold particles. The entire system features a high degree of automation, smooth operation, and seamless integration between each stage, realizing truly “efficient, intelligent, and continuous” processing.

Project Implementation Timeline

The project was meticulously managed throughout its entire lifecycle, from conceptual design and equipment manufacturing to on-site installation and commissioning, with strict control over both quality and schedule. Leveraging a mature technological framework and highly 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 or exceeding design specifications, and has stood the test of prolonged exposure to challenging on-site working conditions.

Application Results and Benefit Analysis

The deployment of the Yake-customized beneficiation vessel has brought revolutionary improvements in production, fully achieving the project’s anticipated objectives:

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

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

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

4. Drastically shortened investment payback period: Thanks to efficient output and excellent cost control, the project’s investment payback period has been reduced to just 8–10 months, achieving rapid capital recovery 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 is not only technologically advanced and reliably performant but, more importantly, adept at precisely addressing real-world challenges on-site—truly delivering “customized solutions with outstanding practical results.” Following the equipment’s commissioning, mining productivity has improved markedly, corporate competitiveness has strengthened considerably, 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 additional technological innovations and applications across various mineral development fields.
