Why Choose Xinhai

Six Reasons Mining Owners Trust Xinhai

Ore-Dressing Test Lab

Every flowsheet starts with bench and pilot test work in our own research institute, so equipment selection is driven by your ore.

In-House Manufacturing

Mills, flotation cells, separators and thickeners are built in Xinhai's own plant under one quality system.

True Turnkey EPCM+O

One accountable partner from design through operation removes interface risk and shortens schedule.

Eco-Friendly Processes

Our CNLITE gold dressing agent replaces sodium cyanide for low-toxicity leaching, backed by ISO 14001.

Global Project Experience

Plants commissioned across five continents give us insight into local ores, climates and logistics.

Lifecycle Support

Multilingual engineers, operator training and managed spare-parts supply keep your plant running.
