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
Three manufacturing bases covering about 110,000 m², a CNAS-accredited test laboratory and 30+ years of flowsheet experience stand behind every project.
Integrated manufacturing base
Three intelligent manufacturing bases covering about 110,000 m², 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
A CNAS-accredited laboratory and an industrial-scale pilot base for bench tests through semi-continuous pilot runs, so the 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
