Tanzania Field Research · Magnetic Gravity Method
Advancing Gold Recovery Through Magnetic Gravity Science
Pioneering mercury-free gold processing technology developed through field research across Tanzania's primary gold-bearing regions.
The Process
Three Stages. One Breakthrough.
The magnetic gravity method combines ferrofluid physics with precision density separation to isolate gold particles with unmatched efficiency.
Magnetic Fluid Preparation
A stable ferrofluid suspension is formulated with calibrated magnetic susceptibility matched to the target ore's mineralogy and particle size distribution.
Gravity Separation
Ore slurry is introduced into the magnetic field gradient. Gold particles, due to their density contrast, migrate along predictable trajectories toward the collection zone.
Gold Extraction
Concentrated gold fraction is recovered from the separation chamber. The ferrofluid is regenerated and recirculated, producing zero mercury waste.
Key Advantages
Why Magnetic Gravity Outperforms Conventional Methods
Higher Recovery Rate
Consistently achieves gold recovery rates up to 94.7% across ore grades from 0.5 to 15 g/t — outperforming cyanidation and gravity-only methods in controlled field trials.
Mercury-Free Process
Eliminates mercury amalgamation entirely. Compliant with the Minamata Convention and Tanzania's Environmental Management Act, reducing environmental liability to zero.
Cost Reduction
Reduced reagent costs, lower energy consumption, and simplified infrastructure requirements deliver up to 42% cost reduction versus conventional cyanide leach circuits.
Processing Efficiency
Throughput efficiency increases of 38% versus conventional methods, with modular unit design enabling rapid deployment at artisanal and large-scale mining operations.

Field Research
Rooted in Tanzania's Gold Country
Tanzania is the fourth-largest gold producer in Africa, with significant deposits concentrated in the Lake Victoria Goldfields (Geita, Mwanza, Shinyanga) and the Lupa Goldfield in Mbeya. These regions host both large-scale industrial operations and an estimated 1.5 million artisanal and small-scale miners.
The magnetic gravity method was specifically developed to address the mineralogical characteristics of Tanzanian ores — fine-grained free gold, complex sulfide associations, and variable oxide weathering profiles. Field trials confirm consistent performance across the full range of ore types encountered in Tanzanian operations.
