What sits inside E, P and C

Engineering

Project consulting, metallurgical testing at laboratory and semi-industrial scale, mine planning and design, flowsheet development, plant design, equipment selection and cost estimation, tailings storage design, plus slope stability, blasting and backfill test work.

Procurement

Mining and processing machinery, installation and support materials, modular buildings, steel structure workshops and complete modular production lines, manufactured then packed and shipped as one scope.

Construction

Shaft and tunnel work, drilling and blasting, plant foundations and buildings, tailings dam construction with seepage control and monitoring, steel structures, prefabricated site buildings, equipment installation and commissioning.

Held under a Class A construction qualification

Mine engineering general contracting is licensed in China, and the Class A grade is the level below the special grade. Xinhai holds it through Yantai Xinkuangfu Engineering Management Group. The entry requirements are the reason the qualification matters commercially: net assets above RMB 100 million, at least 12 first class registered constructors in mining engineering and at least 3 in electromechanical engineering.

Class A general contracting for mine engineering

Where cost and schedule usually leak

Failure patterns and countermeasures as set out in the Xinhai EPC+O brochure.
Symptom	Root cause	Countermeasure in scope
Capital cost overrun	Design copied rather than derived from the orebody	Flowsheet from test work, one design per orebody
Late start-up	Equipment mismatch and uncoordinated site works	Capacity matched across the circuit, installation simulated before mobilisation
Rebuild immediately after commissioning	No owner of the plant after handover	Commissioning to nameplate, then optional operation contract

Construction and installation

Excavator working at a mine site — Earthworks

Processing plant under construction on site — Plant erection

Conveyor and screening structure at a plant — Conveying and screening

Leaching tanks installed at a gold plant — Tank farm installation

Process piping and tanks inside a plant — Process piping

Crew working at an underground face — Underground works

Common questions

What does Xinhai's EPC scope include?

Engineering from test work to detailed design, supply of processing and mining equipment plus installation materials, steel structures and modular buildings, and construction covering mining works, plant civil works, tailings facilities, steel erection, installation and commissioning.

Does Xinhai hold construction qualifications?

Yes. The group holds the Class A general contracting qualification for mine engineering through Yantai Xinkuangfu Engineering Management Group, alongside professional construction contracting, blasting and tailings storage design qualifications.

How is overseas logistics handled?

Packing, shipping and customs clearance are planned against the complete equipment list rather than per package, and installation is simulated on site conditions before mobilisation.

Send us the ore, the tonnage target and the site conditions. We reply with a scoped proposal.

Every Xinhai proposal starts from test work, not from a catalogue. Tell us where the project stands and our engineers will come back with the delivery model, the scope split and the next step.
