After completing the Henan 1,500 t/d silver-lead-zinc-gold polymetallic ore flotation expansion EPC project in 2024, Xinhai Mining has once again been chosen to deliver a technical upgrade for both the primary and secondary concentrators. The client, a Canadian-listed company, is known for strict quality and performance standards. Their decision to continue working with us highlights their trust in our proven execution, strict quality control, and full-service capabilities.
Henan Fanende Concentrator is one of China's key polymetallic ore facilities. It operates two concentrators and two wet tailings ponds. The primary concentrator handles 700 t/d, while the secondary runs at 3,000 t/d, giving a total annual throughput of 1.2 million tons. The client requires top standards in safety, reliability, and environmental compliance.
In 2024, Xinhai Mining delivered a 1,500 t/d flotation expansion project, which increased the secondary concentrator's capacity to 3,000 t/d. The entire process—design, manufacturing, installation, and commissioning—was completed to spec on the first attempt. The project boosted recovery rates and won strong client praise. That success made the client turn to us again without hesitation for this upgrade.
This choice proves the value of Xinhai's EPC+M+O full-industry-chain service. It reflects our consistent commitment to quality, on-time delivery, and compliance.
This upgrade focuses on two key areas:
1. Technical Upgrade of the 700 t/d Primary Concentrator Concentrate Dewatering Plant
Build a new φ12m thickener.
Build a new concentrated dewatering plant.
Expand concentrated storage facilities.
2. Intelligent Wastewater Treatment Project for the 3,000 t/d Secondary Concentrator
Add an intelligent classification and fine sludge disposal system.
Upgrade tailings treatment and wastewater recycling systems.
The project includes both process technology and civil works. It is critical for improving efficiency and supporting green environmental goals. Civil construction has already started. Since our team arrived on site in June 2025, the work has closely followed the design drawings. Full completion is scheduled for November 2025.
This project also showcases Xinhai's strength in civil engineering, alongside process design and equipment supply.

2. Strict Quality Control
Designs are customized to match process flows and site conditions.
Material procurement follows strict acceptance standards. Steel and concrete undergo detailed testing.
On-site managers track progress daily to keep the project on schedule
3. Seamless Integration of Construction and Installation
We coordinate civil works and equipment installation in parallel. This avoids downtime, speeds up progress, and ensures on-time delivery.
Through these measures, Xinhai guarantees safe and efficient construction, building strong client confidence in our delivery reliability.
The client demands more than on-time delivery. They also require strict results in recovery, energy control, environmental compliance, and safety.
At Henan Fanende, Xinhai has delivered:
Micro-bubble flotation at natural pH (6.5–7.0), cutting energy use and protecting the environment.
Recovery rates of 95.5% for lead, 95% for silver, and 92% for zinc—above industry averages.
Zero wastewater discharge, showing strong environmental performance.
Zero accidents across design, construction, and commissioning.
From the 2024 expansion to the 2025 upgrade, Xinhai has consistently delivered end-to-end solutions—process, equipment, civil works, installation, and commissioning—under its EPC+M+O model. The client's repeated choice proves their trust in both our service model and civil engineering expertise.
Looking ahead, Xinhai will continue to pursue excellence and deliver high-quality EPC solutions for global mining projects—setting new industry benchmarks and driving greener, more efficient mining worldwide.
