Mineral Processing Solutions for Every Ore
Xinhai tests your ore, designs the flowsheet, manufactures the equipment and builds the plant — a single-source EPC+M+O partner for gold, copper, lithium, iron, chrome and more. 2,500+ mines served across 100+ countries.
The right flowsheet for your mineral
Every ore behaves differently. We match the process — gravity, flotation, magnetic, leaching — to your mineralogy, grade and target product.

Buying machines from a dozen vendors leaves the integration risk with you. Xinhai takes single-source responsibility for the whole project.
- Engineering (E): ore testing, process design, plant & tailings layout.
- Procurement (P): in-house manufacturing of core equipment plus vetted auxiliaries.
- Construction (C): site supervision, installation and commissioning.
- Management & Operation (M+O): staff training and production ramp-up support.
Manufacturing muscle & proven engineering
A 10,000-tonne-class manufacturing base, an in-house mineral test center and 30+ years of flowsheet experience stand behind every project.
Integrated manufacturing base
10,000-tonne-class works with 1,000+ equipment models and large-unit capability — up to φ7 m ball mills, 320 m³ flotation cells and φ100 m thickeners.
In-house mineral testing
3,000 m² research & test center for bench-scale and semi-continuous pilot testing, so every flowsheet is proven on your ore before it is built.
Single-source EPC+M+O
One accountable contract from ore testing and process design through manufacturing, construction, commissioning and operation support.
Global delivery & service
Project teams experienced across Africa, Asia, Latin America and Eastern Europe, with installation, training and after-sales on site.
- Class-A Mining Engineering Contracting License
- CNAS-Accredited Test Laboratory
- CE Certification
- ISO 9712 NDT
- CWB Welding Certification
