Study on new process of removing iron from potassium feldspar

A study on a new process of removing iron from potassium feldspar has been conducted. Here are some highlights of the study:

1. Background: Iron impurities often decrease the value of potassium feldspar, which is widely used in the ceramics industry. Although conventional methods can remove iron from potassium feldspar, they have some limitations, such as high cost, energy consumption, and environmental pollution.

2. New Process: The new process involves using a combination of magnetic separation and flotation, which can effectively remove iron impurities from potassium feldspar while reducing energy consumption and environmental pollution.

3. Magnetic Separation: The study found that using magnetic separation with a low-intensity magnetic field of 0.10 T can effectively remove iron minerals from potassium feldspar while preserving the iron-free feldspar particles.

4. Flotation: The researchers also tested flotation, in which a cationic collector was used to selectively float potassium feldspar particles. The results showed that the combination of magnetic separation and flotation achieved a potassium feldspar concentrate with a K2O content of 12.06% and an Fe2O3 content of 0.36%.

5. Optimization: The study also optimized the process conditions, including variations in pH, collector dosage, and depressant dosage, to achieve the best separation results.

Overall, the study found that the combination process of magnetic separation and flotation is effective in removing iron from potassium feldspar while offering lower energy consumption and reduced environmental impact. The study proposes a new approach to the beneficiation of potassium feldspar that can increase the value of the resource and reduce waste.

The above table summarizes the key findings and results from the study on a new process of removing iron from potassium feldspar. The study proposed a new approach to beneficiation that combines magnetic separation and flotation to remove iron impurities from potassium feldspar while reducing energy consumption and environmental impact. The magnetic separation step effectively removes iron minerals from the potassium feldspar, while the flotation process selectively separates potassium feldspar particles. The combination process produces a potassium feldspar concentrate with a K2O content of 12.06% and an Fe2O3 content of 0.36%. The study also optimized the process conditions to achieve the best separation results.
