Etibor® 48 is widely used as a flux in precious metal refining, helping to:
- Lower melting point of ores and concentrates
- Remove impurities and slag
- Improve metal recovery and purity
2. Glass Manufacturing
- Improves thermal and chemical resistance
- Enhances durability and clarity
- Used in borosilicate glass production
3. Ceramics & Enamels
- Acts as a flux to lower firing temperatures
- Improves glaze smoothness and strength
4. Detergents & Cleaning Products
- Water softening agent
- Enhances cleaning efficiency
- Stabilises formulations
5. Agriculture
- Source of boron micronutrient for crops
- Corrects boron deficiencies in soil
Application Guidance
In Gold & Silver Refining
| Step | Guidance |
|---|---|
| Mixing | Blend Etibor® 48 with other fluxes (e.g. silica, soda ash) |
| Dosage | Typically 5–15% of total flux mix (depending on ore composition) |
| Furnace Use | Add during smelting to assist slag formation |
| Temperature | Operate within standard smelting ranges |
| Slag Removal | Remove slag to isolate purified metal |
Best Practice Tips
- Adjust flux composition based on ore analysis
- Store in dry conditions to prevent caking
- Use appropriate protective equipment during handling
- Conduct small scale tests before full production
