Total Solution for Gold Ore Beneficiation: Tailor-made to Maximize Gold Value

I. Overview: Precise Matching, Efficient Recovery

Gold resources are complex and varied, ranging from easy-to-select alluvial gold ores to difficult-to-process micro-fine grained leached rock gold ores, and there is no universal beneficiation method that can be applied to all cases. We offer a full range of gold beneficiation solutions, covering the mainstream processes of re-election, flotation, cyanidation (CIL/CIP), heap leaching, etc., and we specialize in combining them into a combined process. Through in-depth research on ore characteristics, we customize the beneficiation solution with the best technical and economic indexes for each customer to ensure the maximum return on investment.

Classification and application of core solutions

1. Alluvial Gold Ore Beneficiation Solution

• Applicable o res: riverbed, river bank, seashore alluvial ores, where gold exists in the form of free natural gold.

• Core process: taking gravity separation as the core, utilizing the difference in density between gold and veinstone for sorting.

• Typical process: sieving and removing impurities → washing and desliming → jigger/centrifugal concentrator roughing → shaking table selection → amalgamation/smelting.

• Advantage: small investment, quick effect, no chemical pollution, very high recovery rate of coarse gold.

2. Rock gold ore re-election solutions

• Applicable o res: Primary ores with coarse free gold embedded in quartz veins, which can be used as pretreatment or main process.

• Core process: Early recovery of dissociated coarse-grained gold in the crushing and milling process to prevent the loss of over-crushing.

• Typical process: crushing → grinding (rod/ball milling) → jigger/shaker to recover coarse-grained gold → tailings into flotation or cyanidation process.

• Advantage: Early output of composite gold, rapid return of funds, reduce the load and cost of subsequent processes.

3. Gold ore flotation solution

• Applicable o res: ores with close relationship between gold and sulfide (e.g. pyrite, poisonous sand); copper, antimony, carbonaceous gold ores which are difficult to cyanide treatment.

• Core process: enrich gold-bearing sulfides into concentrate by means of high efficient collectors and inhibitors.

• Typical process: grinding → slurry mixing → flotation (one rough, two sweeps, three fines) → gold concentrate dewatering for sale or roasting-cyanidation treatment.

• Advantage: it can comprehensively recover the associated non-ferrous metals, and has good effect on the recovery of fine-grained embedded gold.

4. CIP/CIL cyanidation solution for gold ore

• Applicable ore: fine grained leaching oxidized ore or primary ore, gold is dispersed in the form of micro-fine grains.

• Core process: cyanide leaching + activated carbon adsorption, which is the mainstream technology for modern gold extraction.

  • CIL (Carbon Immersion Leaching): leaching and adsorption at the same time, shorter process, more economical investment.

  • CIP (carbon slurry method): first leaching and then adsorption, applicable to ores with high gold grade or complex mineral composition.

• Typical process: grinding → thickening → leaching and adsorption (CIL/CIP tanks) → desorption and electrolysis of gold-carrying carbon → smelting.

• Advantages: high recovery rate (usually >90%), mature technology, high degree of automation, and obvious scale effect.

5. Gold ore heap leaching solution

• Applicable o res: low-grade oxidized ores, off-site ores or waste rocks of large-scale gold mines.

• Core process: build a heap of crushed ore, leach it by spraying with sodium cyanide solution, and then use activated carbon adsorption or zinc powder replacement to recover gold after the precious liquid flows into the precious liquid pool.

• Typical process: crushing (up to -50mm) → stacking → spray leaching → precious liquid collection → zinc powder replacement/carbon adsorption → smelting.

• Advantage: Minimum investment and operation cost, the most economical method to treat low-grade ore.

Advantages and value of the program

• Mature and reliable technology: all processes have been verified in hundreds of projects around the world, with stable technical indicators and controllable risks.

• Customized design: No "one size fits all". We conduct tests based on your ore reports (or ore samples) and recommend the only most suitable process route.

• Maximize economic benefits:

  • For high-grade ores, pursue high recovery rates.

  • For low-grade ores, prioritize low-cost options (e.g. heap leach).

  • Optimize the balance between investment and return through combined processes (e.g., re-election + flotation + CIL).

• Green environmental protection: Provide complete cyanide degradation, wastewater recycling, tailings dry stacking/filling programs to ensure environmental protection standards are met.
