• लाभ:
  • Increases cost efficiency by reducing wastage.
  • Maximizes product uniformity and quality.

10. Plasma Purification

• विवरण: High-temperature plasma removes impurities through vaporization or chemical reactions.
• आवेदन: Advanced process for graphite and silicon applications (e.g., in semiconductors).
• लाभ:
  • Produces ultra-pure minerals for critical industries.
  • Reduces reliance on other chemical-intensive processes.

Combine Technologies for Maximum Value

In many cases, a combination of these technologies is used to achieve desired purity and functionality. For example:

• Kaolin: Typically purified through a combination of flotation, magnetic separation, and chemical leaching.
• Silica: Often enhanced using chemical leaching, magnetic separation, and ultrafine milling.
• ग्रेफाइट: Purified using flotation, thermal treatment, and advanced plasma purification.

निष्कर्ष
