01
Prepare and classify
Ore is sampled, characterized, and sized to establish a feed profile. Liberation behavior and gangue composition guide the trial configuration.
The method
A magnetic liquid pathway for fine-gold recovery.
Magnetic Gravity Gold Processing combines controlled magnetic-fluid behavior with gravity separation to create a mercury-free recovery pathway for suitable gold-bearing ores.
Process principle
Separate by response, density, and control.
Magnetic-fluid-assisted separation
The method uses a magnetically responsive liquid medium to create a controllable separation environment. Under a magnetic field, particles experience different effective forces according to their density, size, and magnetic response.
Gold-bearing material is prepared, introduced to the separation stage, and evaluated through a repeatable recovery circuit. The objective is to concentrate valuable fine fractions while reducing dependence on mercury amalgamation.
Three-stage process
From prepared ore to concentrated recovery.
02
Apply magnetic gravity separation
Prepared material enters a controlled magnetic-fluid environment. Field strength, flow, and medium behavior are adjusted to support density-based separation.
03
Recover and verify
Concentrates are collected and assessed against feed and tailings data. Recovery, grade, and operating inputs are reviewed before any scale-up decision.
Separation environment
A controlled field around every particle.
The separation stage is designed to make particle behavior observable and adjustable. Magnetic field intensity, fluid response, and feed conditions are treated as linked variables—not isolated settings.
Magnetic field
Creates the controlled force environment.
Responsive liquid medium
Transfers field effects through the separation zone.
Gold-bearing concentrate
Collected for assay and recovery analysis.
Technical evaluation
What a site-specific trial examines.
Ore characteristics
Mineralogy, liberation size, clay content, sulfide association, and feed variability.
Circuit conditions
Particle sizing, feed rate, water balance, magnetic intensity, and medium behavior.
Recovery evidence
Head grade, concentrate grade, tailings assay, mass pull, and repeatability across samples.
Operating fit
Energy demand, reagent requirements, operator workflow, maintenance, and modular deployment.
Conventional methods
A different approach to the recovery challenge.
Mercury amalgamation
Relies on mercury to capture gold; creates health and environmental exposure concerns.
Mercury-free magnetic gravity separation
Gravity-only circuits
Can lose fine or complex gold fractions when density separation alone is insufficient.
Magnetic-fluid-assisted control
Cyanidation
May require chemical handling, longer retention, and more complex infrastructure.
Lower-complexity physical separation pathway
A method for evaluation—not a universal claim.
Magnetic gravity processing is assessed against the specific ore, operating context, and recovery target at each site. Controlled trials are essential before selecting equipment or defining a processing route.
