Xinhai delivers end-to-end mineral processing solutions tailored to each ore: we test your sample, design the flowsheet, manufacture the equipment, and build and commission the plant. Solutions cover gold, copper, lead-zinc, lithium (spodumene), iron, chrome, tin, manganese, molybdenum and silver, backed by 2,500+ mine projects across 100+ countries.

The dominant separation method is set by how the valuable mineral is locked in the ore and how it differs from the gangue — by density, surface chemistry, magnetic susceptibility or solubility. Most plants combine two or three of these. Use the table as a starting point, then confirm the route with a bench-scale test on your own sample.
| Ore | Dominant process route | Core equipment |
|---|---|---|
| Gold (free-milling) | Gravity + CIL/CIP cyanidation | Centrifugal concentrator, leaching tanks, elution-EW |
| Gold (refractory) | Flotation + pretreatment + leaching | Flotation cells, agitation tanks |
| Copper / molybdenum | Froth flotation | Ball mill, flotation cells, thickener |
| Lithium (spodumene) | Crush–grind, DMS + flotation | Crushing, flotation, magnetic separation |
| Iron | Magnetic separation (wet / dry) | Wet drum & dry separators |
| Chrome / tin / manganese | Gravity concentration | Spiral chute, shaking table, jig |
| Lead-zinc | Selective (differential) flotation | Flotation cells, classifiers |

Frequently asked questions
How do you decide gravity vs flotation vs leaching?
By mineralogy. Coarse, liberated heavy minerals (free gold, cassiterite, chromite) favor gravity; fine sulfides (copper, lead-zinc, refractory gold) favor flotation; dissolved-recoverable gold/silver favors cyanide leaching. Most flowsheets combine routes — e.g. gravity ahead of leaching to catch coarse gold and cut reagent cost.
What do you need from me to design a flowsheet?
Ideally a representative ore sample (a few kg) or a full assay, plus your target capacity (t/d), head grade, desired product and site constraints (power, water, climate). With that we can test, design and quote.
Can you supply just equipment instead of a full plant?
Yes. Xinhai supplies individual machines (OEM/ODM) as well as complete turnkey plants under EPC+M+O. The same engineering team sizes the units either way.
Which ores do you have experience with?
Gold, silver, copper, lead-zinc, molybdenum, lithium (spodumene), iron, chrome, tin, manganese and several industrial minerals — across 2,500+ mine projects in 100+ countries.
