• Application: Required for high-purity quartz sand (e.g., Fe?O? ≤ 0.02%) to separate feldspar and mica (similar density to quartz, not removable by magnetic separation).
• Principle: Under acidic conditions (pH 2–3), with flotation reagents (e.g., amine collectors, sodium fluorosilicate depressant), feldspar and mica attach to air bubbles and float, while quartz remains in the slurry.
• ????: ????? ??? ?????, ????? ??? ??????? (??? ??-???? ????? ??????? ??????).

(5) ????? ???? (????? ???? ??? ????? PV/??????????)

• Application: When ordinary processes cannot meet high-purity requirements (e.g., Fe?O? ≤ 0.005%).

  • Roasting-Acid Leaching: First roast quartz sand at 600–800°C to convert refractory iron impurities into soluble forms, then remove them via acid leaching.
• ??? ?????: After acid leaching, wash with purified water to neutrality (pH 6–7) to avoid residual acid affecting product quality.

4. ????? ?????? (???? ?? concentrate ????)

• 1. Purified slurry enters a ? thickener for concentration via gravity settling, increasing underflow density to 60%–70%.
• 2. Concentrated slurry is fed to a Filter Press or Vacuum Filter to dewater to ≤ 10% moisture content.
• 3. The filter cake is dried in a Rotary Dryer (120–150°C) to obtain dry quartz sand concentrate.

The standard process can be flexibly adjusted depending on the raw ore’s initial SiO? content, impurity types (including chromium, titanium presence), and target purity levels. Custom solutions require detailed raw ore assay data for optimization.
