Peak recovery rate
Highest observed recovery under optimized magnetic gravity conditions.
Research & results
Measured recovery. Field-relevant evidence.
A growing body of laboratory and controlled field work shows how magnetic gravity separation can recover fine gold while reducing dependence on mercury and high-complexity chemical processing.
Study framework
A research program designed to be tested, not merely described.
Controlled field and laboratory evaluation
The research program evaluates magnetic gravity separation across representative gold-bearing materials, with attention to particle size, mineral association, feed preparation, and recovery behavior.
Results are interpreted alongside practical operating considerations: water use, reagent requirements, energy demand, throughput, and the ability to deploy modular equipment in field conditions.

What the data suggests
Four areas for technical due diligence.
Fine-particle opportunity
Magnetic gravity separation may improve recovery of fine gold fractions that are commonly lost in conventional gravity circuits.
Reduced chemical dependence
The process concept is designed to limit reliance on mercury and reduce reagent intensity in suitable ore contexts.
Ore-specific configuration
Feed characteristics remain decisive. Mineralogy, liberation size, and gangue behavior must be assessed before deployment.
Field validation remains essential
Reported results establish a basis for further trials; they do not substitute for a site-specific metallurgical program.
