• Function: Ṣe ẹka slurry ti a fa jade lati yọ ohun elo to yẹ silẹ labẹ 200 mesh (ti o ni ọlọrọ ninu irin ati awọn impurities aluminiomu).
• Ẹrù: Hydrocyclone: Hydrocykloni, Ẹrọ idapọ ọwọn ti o tẹẹrẹ.
• Operation: Cyclone overflow (slime) ni a fọwọsi; underflow (kòkòrò quartz sọnà) lọ si yọ irin.

(3) Iya mẹta àtọ́ka tẹ́lè (Yiyọ́ ìpẹ̀yà àìmọ́)

• Function: Igbesẹ pataki lati yọ irin afẹfẹ (àpẹẹrẹ, magnetite) ati irin afẹfẹ to rọ (àpẹẹrẹ, hematite, limonite).
• Àpapọ̀ Ẹrọ: Iyapa Magnetik Atilẹyin-kekere (yọ irongun, magnetite) + Iyapa Magnetik Atilẹyin-giga (yọ irin ti ko lagbara, irin-titani oxides).
• Awọn Paramita Pataki: High-intensity magnetic field strength 10,000–15,000 Gauss; slurry flow velocity 0.5–1.0 m/s to ensure full adsorption of magnetic impurities.

(4) Ikọlu (Yiyọ ewu-ara ti ko ni magneti bii Mica, Feldspar)

• Application: Required for high-purity quartz sand (e.g., Fe₂O₃ ≤ 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.
• Ẹrù: Ẹrọ Ilana Iru Ibi Afẹfẹ, Ẹrọ Afẹfẹ Ti a Fẹfẹ (iri-irin afẹfẹ pupọ fun yiyọ idoti patapata).

• Awọn aṣayan ilana:
  • Iru ẹjẹ: Fi slurry naa sinu asọ ti a dapọ (hydrochloric, sulfuric, hydrofluoric) lati jẹ ki irọnu ati aluminiomu oxides ti o ku jẹ.
  • 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.
• Igbese Pataki: After acid leaching, wash with purified water to neutrality (pH 6–7) to avoid residual acid affecting product quality.

4. Iru-òjò àti Yiyọ Ọrọ (Gbigba Ijẹun Kaka)

• 1. Purified slurry enters a Sise pọ̀n. 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.
• 4. A ṣe itọkasi ikojọpọ ti a gbooro pẹlu Ẹrọ Ipa lati yan awọn ọja ti a ti pari ti awọn pato oriṣiriṣi (fun apẹẹrẹ, iyanrin ti ko ni irọrun, alabọde, iyanrin to fine) da lori awọn ibeere iwọn.

The standard process can be flexibly adjusted depending on the raw ore’s initial SiO₂ content, impurity types (including chromium, titanium presence), and target purity levels. Custom solutions require detailed raw ore assay data for optimization.
