Gravity Processing Delivers Outstanding Initial Results
The first-pass test results have exceeded expectations by demonstrating that gravity separation is not only cost-effective but also highly efficient. The method eliminates the complexities and expenses associated with chemical reagents, unlike other processes such as flotation.
Viking Mines recorded key performance metrics during testing:
- Feed Grade: 1.4% WO₃
- Concentrate Grade: 22.9% WO₃
- Grade Increase: 16x multiplication
- Recovery Rate: 63.7%
- Processing Method: Gravity separation
These impressive figures highlight the project’s potential in delivering a sustainable and scalable technology solution. The successful implementation of gravity processing underlines the economic merits of the tungsten grade upgrade, a process that is pivotal to achieving low-CAPEX development.
How Does Gravity Separation Work?
Gravity separation exploits the density differences between scheelite and waste rock. The process involves a physical separation that requires less chemical input and complex infrastructure. This method is ideal for tungsten extraction because it relies on simple mechanical means.
By focusing on this technique, Viking Mines avoids costly reagents and reduces both capital expenditure and operational costs. Such efficiency makes gravity separation one of the most attractive processing methods for critical metals in today’s competitive mining environment.
Optimisation Programme and Testwork Details
The optimisation programme evaluated three different grind sizes to determine the most effective combination of grade enhancement and recovery rate. The coarsest grind size of 200µm delivered the best performance, reaffirming the benefits of less aggressive processing.
Below is a table summarising the performance metrics for each grind size:
| Grind Size | Feed Grade | Concentrate Grade | Recovery |
|---|---|---|---|
| 200µm | 1.4% WO₃ | 22.9% WO₃ | 63.7% |
| 160µm | 1.1% WO₃ | 22.7% WO₃ | 42.0% |
| 125µm | 1.1% WO₃ | 17.0% WO₃ | 49.7% |
The table clearly demonstrates the advantage of using coarser grind sizes. With minimal waste interference, Viking’s approach positions the tungsten grade upgrade as both technically and economically superior.
Fast-Track Development Strategy and Next Steps
Viking Mines is leveraging these encouraging results as part of its fast-track development strategy. The company is committed to optimising the process further, with several immediate next steps lined up to enhance overall efficiency and recovery.
Immediate next steps include:
