From ore testing and plant design to equipment manufacturing, construction and operation — Xinhai delivers one complete, accountable mineral processing solution for your mine.
A single contract covers every stage of your concentrator — eliminating the gaps, delays and finger-pointing that arise when design, equipment and construction are split across vendors.
A complete in-house range covering every unit operation in a beneficiation flowsheet — grinding, flotation, gravity and magnetic separation, gold extraction, classifying, thickening and dewatering.
Wet and dry overflow and grate ball mills for primary and secondary grinding, with rolling-bearing drives that cut energy use against traditional sliding-bearing designs.
SF, XCF/KYF and JJF/Wemco pneumatic-mechanical flotation cells that recover copper, lead-zinc, gold, fluorite and other minerals with high concentrate grade and recovery.
High-temperature, high-pressure desorption and electrowinning systems that strip loaded carbon and recover gold quickly — the core of CIP/CIL gold rooms.
Centrifugal concentrators, jigs, spirals and shaking tables that capture free gold and heavy minerals with no reagents — ideal for pre-concentration and scavenging.
Centre-drive, peripheral-drive and deep-cone high-efficiency thickeners that recover process water and densify tailings — lowering water cost and easing tailings storage.
Pre-assembled, modular flowsheets — CIP/CIL gold, copper flotation, iron magnetic and more — engineered, fabricated and shipped as one coordinated package.
For nearly three decades, Xinhai has combined its own ore-dressing research, in-house manufacturing and field-proven EPCM delivery to de-risk mineral projects worldwide.
Every flowsheet starts with bench and pilot test work in our own research institute, so equipment selection is driven by your ore — not guesswork.
Mills, flotation cells, separators and thickeners are built in Xinhai's own plant under one quality system — stable output, traceable parts, on-time delivery.
One accountable partner from design through operation removes interface risk between consultants, suppliers and contractors — and shortens schedule.
Our CNLITE gold dressing agent replaces sodium cyanide for low-toxicity leaching, backed by ISO 14001 environmental certification.
Plants commissioned across Africa, Asia, Europe, Oceania and the Americas give us hard-won insight into local ores, climates and logistics.
Multilingual engineers, operator training and a managed spare-parts supply keep your concentrator running long after handover.
Whether you are recovering gold, base metals, lithium or industrial minerals, Xinhai matches the right crushing, grinding, separation and concentration circuit to your deposit.
CIP, CIL, heap-leach and gravity-flotation circuits for free-milling and refractory ores.
Differential and bulk flotation to produce clean, high-grade copper, lead and zinc concentrates.
Magnetic separation, jigging and flotation to upgrade hematite, magnetite and manganese ores.
Heavy-media, flotation and magnetic circuits for battery-grade spodumene concentrate.
Selective flotation that delivers acid-grade fluorspar and high-purity barite products.
Scrubbing, classifying and purification lines for glass-, foundry- and high-purity silica.
From 300 TPD gold plants to multi-million-tonne iron operations — a selection of turnkey concentrators Xinhai has designed, built and commissioned.
A fully automated CIP gold circuit delivering stable recovery in a remote Pacific island setting, with operator training and remote support.
