Gold Ore Processing
Xinhai recovers gold from free-milling, refractory and alluvial ores using the route best matched to your mineralogy and grade — gravity, flotation, CIP, CIL or heap leach, with the eco-friendly CNLITE agent available as a cyanide alternative.
- CIP and CIL gold rooms with desorption-electrolysis
- Centrifugal and gravity recovery of coarse free gold
- CNLITE low-toxicity leaching reagent (cyanide replacement)
Copper & Lead-Zinc Flotation
Sulphide base-metal ores are upgraded by selective and bulk flotation into clean, high-grade saleable concentrates. Xinhai tunes the reagent regime and cell configuration to your ore so you maximise both recovery and concentrate grade.
- Differential flotation for polymetallic Pb-Zn-Cu ores
- XCF/KYF and SF cells matched to circuit duty
- Concentrate thickening, filtration and tailings management
Iron & Manganese Beneficiation
Magnetite, hematite and manganese ores are upgraded through magnetic separation, jigging, gravity and reverse flotation. Xinhai combines these into a single circuit that lifts iron grade while keeping operating cost and water use under control.
- Low- and high-intensity magnetic separation
- Jigging and gravity for coarse liberated ore
- Reverse flotation to reduce silica in concentrate
Lithium & Spodumene Processing
Hard-rock lithium ore is upgraded to battery-supply-chain concentrate through dense-media separation, flotation and magnetic purification. Xinhai has delivered million-tonne spodumene lines, including a two-million-TPA plant in Zimbabwe.
- Heavy-media pre-concentration of spodumene
- Flotation to lift Li₂O grade to concentrate spec
- Magnetic separation to control iron contamination
Fluorite & Barite Flotation
Selective flotation delivers acid-grade fluorspar (≥97% CaF₂) and high-purity barite from complex ores. Xinhai's staged grinding and multi-cleaning circuits hold grade while keeping silica and calcite down.
- Acid-grade fluorspar concentrate production
- Stage grinding to protect fluorite crystals
- Depressant control for silica and calcite
Quartz & Silica Sand Purification
Scrubbing, classifying, magnetic separation and flotation remove iron and impurities to produce glass-, foundry- and high-purity grade silica. Xinhai has built quartz lines up to 900,000 TPA.
- Attrition scrubbing to strip surface iron coatings
- High-intensity magnetic separation for impurity removal
- Flotation for high-purity and ultra-low-iron grades
