Ghana, a leading gold producer in Africa, has long been a focal point for global mining investment. In recent years, Chinese mining enterprises have played an increasingly significant role, not only as investors but as partners bringing advanced technology and sustainable practices. Among them, Xinhai Mining Technology & Equipment Inc. (Xinhai) stands out, exemplifying how Chinese expertise is contributing to Ghana's mining sector through diversified project execution, technological innovation, and a steadfast commitment to green development.
Xinhai's portfolio in Ghana showcases its versatile capabilities, from unlocking value in waste to optimizing conventional ore processing.
The transformative 500t/d gold tailings reprocessing project tackles the challenge of extracting value from historical waste with a stable grade of 2-5 g/t Au. Xinhai implemented an optimized all-sliming cyanidation Carbon-in-Leach (CIL) process—a technology also detailed in our case study on Sudan Gold CIP/CIL Process.
Through precise two-stage grinding to over 85% -200 mesh, finely disseminated gold particles are effectively liberated for recovery. This project is a hallmark of the Green Mine philosophy, designed with sustainability at its core.
It integrates closed-circuit water recycling, eco-friendly tailings management, and energy-efficient operations. This approach ensures the project is not only economically viable but also an environmental leader, successfully turning a historical liability into a productive asset.
Complementing the tailings project is Xinhai's successful delivery of a 1000t/d greenfield gold processing plant, a prime example of a large-scale Gold Processing Plant in Africa. Designed for oxide ore with low sulfur content, the plant employs a combined gravity separation and carbon-in-pulp (CIP) process.
The technical flowsheet features efficient closed-circuit grinding and a multi-tank, counter-current leaching and adsorption system to maximize gold recovery. A complete circuit includes desorption, electrolysis, and carbon regeneration.
A key environmental highlight is the use of cyanide-free leaching reagents, significantly reducing the project's ecological footprint. This facility demonstrates Xinhai's full capability to design, build, and commission efficient and compliant processing plants, effectively converting Ghana's mineral resources into broad economic and social benefits.
Xinhai's long-term commitment to these technical projects is reflected in the establishment of Xinhai Ghana Mining Co., Ltd., in July 2025. This full subsidiary serves as the strategic bridge for "China Technology + Africa Resources," positioning Ghana as a hub for the broader region, delivering proven solutions, such as those implemented at our Gold CIL Plant in West Africa.
Operating on a localization model, it delivers Xinhai's comprehensive "EPC+M+O" services locally. The subsidiary provides tailored solutions—such as steel-structured construction and solar power systems—to address regional challenges like high costs.
By prioritizing local talent recruitment, training, and technology transfer, Xinhai Ghana not only ensures responsive service but also fosters job creation and industry development, rooting its success in shared growth with the community.
Together, the tailings revival and the conventional plant project—backed by a permanent local entity—illustrate a holistic Chinese approach to modern mining. Xinhai delivers integrated value across three pillars:
Economic & Technical Excellence: From advanced tailings recovery to optimized greenfield plant design, ensuring high recovery rates and robust project economics.
Environmental & Social Stewardship: Pioneering cyanide-free reagents, water recycling, and green mine designs to exceed compliance and secure the social license to operate.
Long-Term Partnership: The local subsidiary ensures continuous support, capacity building, and solution adaptation, transforming one-off projects into enduring contributions to Ghana's mining ecosystem.
This model demonstrates that Chinese mining involvement is a partnership focused on transferring sustainable, adaptable technologies that align profitability with responsibility.
Xinhai's multifaceted work in Ghana—spanning innovative waste reprocessing, efficient greenfield construction, and deep local integration—proves that contemporary Chinese gold mining is synonymous with sustainable recovery and green innovation.
By providing technical solutions that are both economically sound and environmentally conscious, and by investing in local operations and people, companies like Xinhai are helping chart a future for Ghana's mining sector that is more productive, resilient, and responsible. This path forward, built on shared expertise and mutual benefit, is the proper foundation for lasting progress and partnership.
