Babban Manufa: Don niƙa ƙarfen ƙura zuwa girman ƙwaya da ya dace don niƙa da kuma raba manyan ƙura da tarkace don guje wa toshewa a cikin kayan aikin da za a bi.

Matakan Tsari:

• 1. Tsohon ma'adanin (dutsen quartz, ma'adanin ruwan quartz) ana shigar da shi cikin silon tsohon ma'adanin ta hanyar mai ɗaukar kaya/mai ba da abinci don tabbatar da cikakken ba da abinci;
• 2. Bargajiya ta farko: Yi amfani da a ƙuraren ƙura to reduce ore size to 50–100 mm to meet the requirements of subsequent finer crushing.
• 3. Fitarwa da Tsarawa: The coarse crushed material passes through a circular vibrating screen (mesh size 10–20 mm). Oversized material is returned for further crushing, while qualified material proceeds to fine crushing.
• 4. Hana (Mai Kyau) na Biyar: Yi amfani da a Mashin na rushewa na kogon or impact crusher to reduce particle size to 5–10 mm, the final crushed product before grinding.
• 5. Cikakken Jirgin Ruwan Kewaye: Ana mayar da samfurin da aka niƙa sosai zuwa ga allon tsere mai jujjuyawa don tabbatar da daidaiton girman ƙwayoyin da kuma gujewa yawan niƙa (wanda ke ƙara wahalar tsarkakewa na gaba).

Muhimman Ma'auni: Crushed product size controlled at 5–10 mm; screening efficiency ≥ 90%.

2. Nika da Rarrabuwa (Inganta Girman Kwayoyin, Fitar da Hawa)

Babban Manufa: Don niƙa ƙwayoyin quartz zuwa launin da ake bukata (misali, -20 mesh, -100 mesh), a cikin cikakken sakin quartz daga datti da aka haɗa (misali, oxides na ƙarfe, mica), don gina tubalin tantancewa na gaba.

Matakan Tsari:

• (1) An aika da kayan da aka murkushe sosai zuwa tukunyar zinariya mai kyau sannan a ciyar da su daidaitacce cikin Wet Kayan dutsen mai ruwan gina ko Ball Mill - Milin Kwallan (ana fifita rod mills don yashi na quartz don rage yawan nika da gurbacewar ƙarfe).
• (2) Samfurin kasa yana shiga Na'urar Rarrabawa (mai zama a kan katafaren gini, hydrocyclone, ko mai rarrabawa na turawa) don raba manyan da ƙananan ƙwayoyi.
• (3) Zaren Kwatanci Mai Rufe: Zafi (babban ƙwaya) daga mai rarrabewa yana komawa kulawa don sake niƙa; zafin da ya wuce (ƙananan ƙwaya masu cancanta) yana ci gaba da tsarkakewa.

Muhimman Ma'auni:

• Girman Nika: An daidaita bisa ga bukatun masana'antu. Bakin gilashi na al'ada yana bukatar fiye da kashi 80% yana wucewa 100 mesh; bakin gilashi na PV/ina da daraja na lantarki yana bukatar fiye da kashi 90% yana wucewa 200 mesh.
• Kauri Slurry: Controlled at 60%–70% during grinding and 30%–40% during classification.

3. Matakan Tsarkakewa na Asali (Cire Gubobi, Inganta Tsabta)

Babban gurɓataccen cikin yashi quartz sune ƙarfe (Fe₂O₃), aluminum (Al₂O₃), mica, da ƙasa, wanda ke buƙatar haɗakar "fizik + sinadarai" tsari.

(1) Tsabtacewa da Cire Kankara (Cire Litan, Rufin Kankara)

• Function: Tasirin na'ura + wanke ruwa mai matsa lamba don cire fim din laka da slim mai kyau daga saman ƙwayoyin quartz (slime na iya rufe datti, yana shafar cire ƙarfe na gaba).
• Kayan Aiki: Drum Scrubber, Spiral Scrubber (wannan yana da tasiri fiye da matakai biyu na wanke-wanke).
• Muhimman Ma'auni: Scrubbing time 15–30 min; slurry density 25%–35%; high-pressure water pressure 0.3–0.5 MPa.

(2) Tsarin Kategorization da Tsabtacewa (Raba Kwallan Kankara na Gajerun Tsutsa)

• Function: A rarraba slurry da aka shafe don cire ƙananan slime ƙasa da 200 mesh (mai yawan ƙarfe da kankara).
• Kayan Aiki: Hydrocyclone, Tushen Teɓɓi mai lanƙwasa.
• Operation: Ana zubar da ruwan tsarin guguwa (slime); ana ci gaba da zubar da karamin ruwa (kwayoyin quartz masu kauri) zuwa cire ƙarfe.

(3) Rarrabawa ta Jijiya don Cire Karfe (Cire Gurɓataccen Jijiya)

• Function: Mataki na asali don cire ƙarfe mai maganadisu (misali, magnetite) da ƙarfe mai ƙarancin maganadisu (misali, hematite, limonite).
• Haɗin Kayan Aiki: Mai rarraba magnetic mai ƙarancin ƙarfin jiki (yana cire ƙarfe mara kyau, magnetite) + Mai rarraba magnetic mai ƙarfin jiki mai yawa (yana cire ƙarfe mai raunin jiki, oxides na ƙarfe-titanium).
• Muhimman Ma'auni: 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) Fitar da ruwa (Cire gurbacen da ba su da magnetic kamar 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.
• Kayan Aiki: Injin Agitation na Injin, Injin Flotation mai Iska (flotation mai matakai da yawa don cire datti sosai).

(5) Tsarkakewar Kimiyya (Muhimmi ga Yashi na PV/Ingancin Lantarki)

• Application: When ordinary processes cannot meet high-purity requirements (e.g., Fe₂O₃ ≤ 0.005%).
• Zaɓuɓɓukan Tsari:
  • Fitar da Acid: Ajiye slurry a cikin haɗin acid (hydrochloric, sulfuric, hydrofluoric) don narkar da sauran ƙarfe da oxides na aluminum.
  • 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.
• Mataki Mai Muhimmanci: After acid leaching, wash with purified water to neutrality (pH 6–7) to avoid residual acid affecting product quality.

4. Kankarewa da Cire Ruwa (Samun Mai Tsabta)

• 1. Purified slurry enters a Mai kauri 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. An rarraba gwanon da aka bushe ta hanyar amfani da Allon Tara tare da tantance kayan kammala daban-daban bisa ga ka'idodin girma (misali, yashi mai kauri, matsakaici, da fadi) bisa ga bukatun girma.

5. Binciken Kayan Aiki da Ajiye Su

• Alamomin Bincike: SiO₂ purity (ordinary industrial sand ≥98.5%, glass sand ≥99.3%, PV-grade ≥99.9%, electronic-grade ≥99.99%), Fe₂O₃ content (ordinary sand ≤0.3%, high-end sand ≤0.005%), particle size distribution, moisture content.
• Storage: An adana yawan yashi da aka gama a cikin silos na musamman don guje wa sake gurbacewa (misali, ƙwanƙwas, kura).

Jerin Kayayyakin Kauri (Tsarin Kawa)

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.
