One contract from ore sample to full production
Xinhai runs the whole chain in house: test work, design, manufacturing, construction and operation. Founded in 1997, we serve mines in more than 100 countries.
EPC+M+O
Five links, one accountable party
Most mine projects break where the contracts meet: the design house blames the equipment supplier, the supplier blames the builder. Xinhai signs for all five links.
Engineering
Consulting, metallurgical testing at laboratory and semi-industrial scale, mine and plant design, tailings design, equipment selection and cost modelling, compliant with international reporting standards.
Procurement
Processing and mining machinery from our own manufacturing bases, plus installation materials, steel structures, modular buildings and complete production lines, packed and shipped as one scope.
Construction
Held under a Class A general contracting qualification for mine engineering: shaft and tunnel work, plant civil works, tailings storage facilities, steel structures, equipment installation and commissioning.
Mine construction management
Design, procurement, construction and commissioning managed as one programme, with one schedule and one quality regime instead of five separate ones.
Operation management
Mining, processing or integrated mine and plant operation under eight cooperation models, from fixed-cost contracts to profit sharing and equity participation.
Where projects usually engage us
Six service lines. Each one can be bought standalone or folded into a turnkey scope.
Test work and research
CNAS accredited laboratory, around 5,000 element analyses per month and roughly 200 test programmes a year, from exploratory tests to semi-industrial pilot runs.
Test work
Full lifecycle mine design
Scoping and PEA through PFS, BFS, FEED, detailed design and issued-for-construction drawings, compatible with JORC, NI 43-101 and VALMIN.
Design
EPC turnkey delivery
Engineering, supply and construction under one contract, executed by our own design institute, factories and construction teams.
EPC
Contract mining and operation
Greenfield ramp-up, operating mines, brownfield upgrades and restarts, run against agreed production, recovery and cost targets.
Operation
Modular processing plants
Shop-assembled and tested modules shipped to site, cutting field construction to foundations and module connection.
Modular
Equipment manufacturing
Three manufacturing bases and more than 1,000 equipment models, including mills up to 7 m diameter and 320 m3 flotation cells.
EquipmentOre types we have processed
Six families, more than 70 ore types. Each solution page carries the route and the reference project.
| Family | Ore types | Typical route | Solution |

| Base metals | Copper, lead, zinc, molybdenum, tungsten, tin, antimony | Bulk or selective flotation with concentrate regrind | Copper, lead-zinc, molybdenum |
| Ferrous metals | Iron, chrome, manganese, vanadium, titanium | Magnetic separation, gravity and flotation combinations | Iron |
| Energy transition minerals | Lithium, graphite, quartz, phosphate, nickel | Flotation plus magnetic separation and dense medium separation | Lithium, quartz sand, phosphate |
| Rare metals | Zircon, titanium, rare earths | Gravity, magnetic and electrostatic separation in series | Zircon and titanium |
| Industrial minerals | Feldspar, fluorite, barite, andalusite, wollastonite | Flotation, gravity and magnetic purification | Fluorite |
