Refractory Gold Ore Processing Solutions

Refractory gold ore sorting solution: OrePartner realizes the value breakthrough of turning "dull ore" into "gold ore" with innovative technology

Refractory gold ores are characterized by complex state of gold existence, close mineral symbiosis, and interference of harmful elements, etc. The traditional cyanidation method has low recovery rate and high cost, and a large amount of gold resources can't be recovered economically and effectively. How to break the technical bottleneck of difficult-to-select gold ores and realize efficient, economic and environmentally friendly gold recovery has become an important issue for the global gold industry.

OrePartner, with its deep technical accumulation and innovation ability in the field of difficult-to-process gold ores, provides an integrated pretreatment-leaching-recovery solution for difficult-to-process gold ores, which helps customers break through the technical barriers and release the potential gold value.

I. Core challenges of difficult-to-select gold ore processing

• Complicated state of gold accumulation: high proportion of difficult-to-process gold such as micro-fine grains encapsulated gold, solid solution gold, and surface-covered film gold.

• Serious mineral interference: arsenic, antimony, carbon, copper and other harmful elements affect the leaching effect.

• More cyanide and oxygen-consuming substances: sulfide, easy-to-float minerals, etc. increase the consumption of chemicals.

• Environmental protection pressure: strict requirements for the treatment of cyanide-containing wastewater and arsenic-containing waste residue.

• Poor economy: low recovery rate of conventional process, unbalanced cost-effectiveness.

OrePartner Refractory Gold Ore Sorting Technology System

We provide innovative technology solutions for the whole process from process mineralogy research, pretreatment technology, leaching process, recovery system to environmental protection treatment.

✅ Core service content:

1. Precise diagnosis of gold endowment state
   Adopting MLA, EPMA, LA-ICP-MS and other advanced means to quantitatively analyze the types of gold minerals, particle size distribution, and embedded characteristics, and provide a scientific basis for process selection.

2. Efficient pretreatment technology

   • Oxidation roasting: arsenic removal, desulphurization, breaking parcels, applicable to arsenic-containing carbon-containing gold ores.

   • Pressurized oxidation: oxidize sulfide under high temperature and high pressure, the gold exposure rate reaches more than 95%.

   • Bio-oxidation: oxidizing sulfide by acidophilus, environmentally friendly and economical, applicable to small and medium scale mines.

   • Chemical oxidation: using ozone, peroxide and other strong oxidizing agents, selective oxidation of interfering minerals.

3. High-efficiency leaching system

   • Environmentally friendly leaching agent: develop non-cyanide leaching systems such as thiosulfate, thiourea, halide, etc.

   • Catalytic leaching: using catalysts to improve leaching rate and recovery rate

   • Enhanced le aching: use ultrasonic, microwave and other physical fields to enhance the leaching process.

4. Advanced Recovery Technologies

   • Resin adsorption: applicable to ores with high sedimentation and impurities.

   • Activated Carbon Innovation: Developing special activated carbon to improve adsorption capacity.

   • Magnetic separation pretreatment: remove cyanide-consuming minerals such as magnetite in advance.

5. Environmental Protection and Resource Utilization

   • Cyanide-containing wastewater treatment: adopting SO₂-air method, hydrogen peroxide method and other high-efficiency cyanide-breaking technologies

   • Arsenic slag stabilization: fix arsenic into stable minerals, safe landfill

   • Comprehensive utilization of resources: recovery of associated valuable elements, improve economic efficiency

Typical application scenarios

We have successfully provided solutions for all kinds of difficult to select gold ores:

• Arsenic-containing gold ore: adopting roasting-oxidation or bio-oxidation-cyanidation process

• Carbon-bearing gold ores: adopting blank roasting or carbonaceous passivation technology

• Complex sulphide gold ores: pressurized oxidation-cyanidation process

• High copper gold ore: selective leaching or flotation pretreatment

• Ultra-fine-grained gold ore: bacterial pre-oxidation or chemical oxidation technology

• Old tailings resources: intensive leaching and resin adsorption process
