FeSi15 Powder in Mineral Beneficiation
Ferrosilicon represents a critical metallurgical additive composed of iron-silicon binary compounds. Its silicon mass fraction adaptively ranges from 15-70% per operational requirements, typically containing trace aluminum impurities.
Primary Deployment of FeSi15 Powder
This predominantly utilized ferroalloy variant achieves critical functionality in density separation systems. Its distinctive physicochemical properties enable essential roles across mineral processing - particularly in gravitational differentiation and dense-phase suspension techniques.
Heavy media is one of the most important methods in the concentration and processing of minerals. Due to its high efficiency and ability to separate materials based on density, this method is used to process a wide range of minerals such as:
– Coal
– Iron ore
– Lead and zinc
– Chrome and manganese
– Tungsten and fluorine
– Diamonds and other precious stones
How ferrosilicon 15% works in diamond separation
To separate diamonds, ferrosilicon15% powder is used. The process is as follows:
1- Ferrosilicon powder is mixed with water to create a solution with a density close to that of diamond.
2- Diamond-bearing materials are immersed in this solution and are affected by the force of gravity.
3- Due to the difference in density, lighter materials rise to the surface and heavier materials sink to the bottom of the tank .
4- Finally, diamonds and other valuable materials are extracted by performing additional processing.
Why is the heavy media method still used?
Through continuous technological advancements, heavy medium separation systems have always been a fundamental mineral processing technology. Its sustained industry prominence stems from three key advantages:
• Unparalleled density-based separation accuracy
•Reduce mineral processing costs
•Compatibility with multiple materials
Conclusion：
Within dense-media separation technology, 15% ferrosilicon powder constitutes the critical suspension agent, maintaining sector dominance in coking coal preparation, iron ore upgrading, and alluvial diamond recovery. The material persists as fundamentally irreplaceable for mineral concentration operations due to its optimized physicochemical specifications.
