As the person in charge of a mineral processing project, you may have felt this way before: there are countless tasks to handle, and every day brings more issues to resolve. When testwork, design, civil engineering, and equipment must each be sourced from different suppliers, simply coordinating with everyone can be exhausting. If there were a single contractor that could take over all these responsibilities—while you only need to oversee the project strategically—wouldn’t that make life much easier?
Today, we’re sharing a real case from Kazakhstan. You’ll see how the project owner turned a stressful, fragmented process into highly efficient collaboration by choosing a true full-process EPC+M+O service provider—and how this allowed him to focus on higher-level project strategy.
The client owns a sulfide copper mine in Kazakhstan, with an average grade of about 0.86% Cu. In theory, he should have been enjoying steady returns, but the reality brought several challenges:
Huge processing scale:
With a capacity as high as 1,500,000 t/a, any mistake in any stage could result in significant losses.
Tight construction schedule:
Market opportunities were limited, and the project needed to progress rapidly and reach production as early as possible.
Coordination difficulties:
If testwork, design, civil construction, and equipment were each handled by separate suppliers, the cross-cultural and cross-time-zone communication alone would be exhausting for the team.
The project owner quickly realized that the “fragmented supplier model” would make it almost impossible to complete a project of this size within the required timeframe. In January 2025, after searching on Google, he discovered Xinhai Mining, a company with years of experience in full-industry-chain mining services. An on-site visit and in-depth discussion convinced him: this was the partner capable of taking on the entire execution workload.
For this project, Xinhai Mining provided a full turnkey commitment. Our four core strengths played a decisive role in ensuring success:
1) Large processing capacity requires mature processes and precise design—and we provided both
Facing a processing scale of 1,500,000 t/a, we leveraged our extensive experience with similar large-scale projects. From the metallurgical testwork stage onward, we prepared the process for industrial-scale operation.
Through accurate beneficiation tests and process design, we ensured a stable, reliable flowsheet and robust equipment selection, laying a solid foundation for long-term, efficient plant operation.
2) Tight schedule? Our full-process integrated management ensured on-time delivery
Parallel engineering:
Within our integrated system, civil construction and equipment manufacturing proceed simultaneously. While foundations were being poured on site, our factory was already producing the core equipment. This parallel—not linear—workflow is the key to shortening construction time.
Seamless coordination:
Design → Civil → Installation all shared one standard and one system.
Our designers and construction teams worked under a unified framework, preventing misunderstandings and rework, and ensuring that every detail from the drawings was accurately reflected in the field.
3) Complete civil engineering coverage
Civil construction is far more than “building structures”—it is the foundation for stable equipment operation. In Kazakhstan, we independently completed all civil works, including:
·Heavy reinforced concrete foundations for crushers and mills
·Steel-structure main plant buildings, crushing workshops, and grinding-flotation workshops
·Ore bins, thickener tanks, and various non-standard structures
·With professional workmanship, our civil team built a solid and reliable “home” for the entire concentrator on foreign soil.
4) A truly full-process EPC+M+O service: the client only needed to “command from the top”
This is exactly the “effortless” scenario described at the beginning of the article. From the moment the ore sample entered our laboratory, to process design, civil construction, equipment manufacturing and delivery, all the way to installation and commissioning—Xinhai Mining handled everything.
The project owner no longer needed to juggle countless interfaces or respond to constant emergencies. He successfully shifted from a “busy firefighter” to a calm, strategic project commander.
The full-process EPC model significantly accelerated the project timeline. From the start of civil construction in October 2025 to the planned commissioning in December 2026, the total construction time is only about 14 months—much faster than the industry average for projects of this scale.
In the end, we delivered impressive performance indicators:
Concentrate grade: 22.00% Cu
Copper recovery rate: 90.00%
The project truly achieved the goal of “early commissioning, early profitability.”
