플루오라이트를 레피돌라이트 농축물에서 분리하는 방법은?
Separating fluorite from lepidolite concentrates involves exploiting differences in their physical and chemical properties through methods such as froth flotation, gravity separation, and magnetic separation. Here is a general outline of the process, though specific methods may vary depending on the mineral composition, particle size, and impurities present:
1. Initial Crushing and Grinding
- 목표: Liberate the fluorite and lepidolite particles from their host rocks.
- Crush the ore to reduce the particle size and then grind to fine particles suitable for separation.
- Ensure that both minerals are sufficiently liberated from each other.
2. Froth Flotation
- 목표: Use chemical reagents to separate fluorite from lepidolite based on surface properties.
Fluorite Flotation:
Fluorite typically responds well to froth flotation due to its surface properties. The procedure involves:
- pH 조절: Adjust the slurry to an acidic or moderately alkaline environment (e.g., pH ~8-9) using lime or other buffering agents.
- 집약제:
Add collectors such as fatty acids, hydrofluoric acid, or sodium oleate to promote fluorite attachment to air bubbles.
- 억제제:
Introduce depressants (e.g., starch or tannins) to inhibit the flotation of gangue minerals or competing lepidolite particles.
- 발포제: Include frothers like pine oil to stabilize the froth for efficient flotation.
Lepidolite Flotation:
Lepidolite, a lithium-bearing mica, can also be separated using froth flotation. Adjust conditions with:
- 집약제:
Amine-based reagents or cationic surfactants that enhance the flotation of lepidolite.
- 억제제:
Use depressants (e.g., sodium silicate) for gangue minerals.
- pH 조절:
Generally, lepidolite flotation requires different pH settings (often alkaline).
Sequential flotation may be applied to carefully separate fluorite first and lepidolite later.
3. 중력 분리
- 목표: Utilize density differences between fluorite and lepidolite to achieve separation.
- Fluorite has a higher specific gravity (~3.0–3.2) compared to lepidolite (~2.8).
- Equipment such as shaking tables, spiral concentrators, or dense media separation techniques can be used to enhance separation.
4. 자력 분리
- Lepidolite may exhibit mild paramagnetic properties due to lithium and iron content, while fluorite is non-magnetic.
- Use magnetic separators to remove lepidolite if there are significant magnetic differences.
5. Differential Chemical Treatment (Optional)
- Acid leaching could be applied to remove any impurities selectively bonded to either fluorite or lepidolite surfaces.
6. Washing and Final Concentration
- Wash the concentrate to remove flotation reagents and improve purity.
- Final drying and particle consolidation for usability and transport.
7. 폐기물 관리
- Safely store or treat the waste material (tailings) to avoid environmental impact.
Notes:
- Testing: Conduct laboratory-scale testing to optimize reagent combinations, dosages, pH levels, and other separation parameters.
- 조정: Factors like the mineralogical composition of the ore or presence of impurities (e.g., quartz) can impact the separation method.
- 경제적 고려 사항: Choose methods that maximize recovery while minimizing costs and environmental impact.
