Services across the mine lifecycle
Buy one link or the whole chain. The scope split is a commercial decision, not a technical constraint, because the same group owns the laboratory, the drawings, the factories and the construction crews.
Six service lines
Test work and research
Element and phase analysis, exploratory and closed-circuit flotation, gravity, magnetic, leaching and biological oxidation tests, then semi-continuous pilot runs before the flowsheet is fixed.
Read moreFull lifecycle mine design
Scoping, PFS, BFS, FEED, detailed design and construction drawings for the mine, the plant and the tailings storage facility, in one design institute.
Read moreEPC turnkey delivery
Engineering, procurement and construction under one contract, including shipping, site installation and commissioning to nameplate.
Read moreContract mining and operation
Eight cooperation models covering production, equipment, safety, environment, staffing and cost management for greenfield, operating, brownfield and restart mines.
Read moreModular processing plants
Standardised modules pre-assembled and tested in the factory, shipped complete, then bolted together on prepared foundations.
Read moreEquipment manufacturing
Crushing, grinding, classification, flotation, gravity, magnetic, gold extraction, thickening, filtration, conveying, pumps and automation, from our own bases.

The three failure patterns below are the ones our EPC+O brochure sets out as the reason the integrated model exists.
| Link | Usual failure | How Xinhai contracts it |
|---|---|---|
| Engineering | The flowsheet is copied from an existing plant and non-standard items are drawn by whoever is available. | One flowsheet per orebody, driven by the test report, with non-standard items reviewed by the responsible discipline. |
| Procurement | Packages are bought separately on lowest price, so machines do not match across the circuit. | Equipment matched to the circuit capacity first, with one specification standard across the plant. |
| Construction | Designs ignore overseas site conditions, material planning slips and installation stalls. | Packing, logistics and customs planned for the whole equipment list, with installation simulated before mobilisation. |
| Management and operation | No one owns the mine after handover, so ramp-up becomes a second project. | Lifecycle management with our own operations team, under a model chosen with the owner. |
