Crude Iodine is a high-purity elemental iodine used in a wide range of industrial, pharmaceutical, and chemical synthesis applications. Cavin Resource offers bulk supply for global buyers, packaged securely and compliant with international transport regulations.

Crude Iodine refers to semi-refined or technical-grade iodine in crystalline form, extracted primarily from natural brines, seaweed ash, or Chilean caliche. This form of iodine retains trace impurities but is suitable for industrial processes, chemical synthesis, pharmaceutical precursors, and iodine compound production.

It appears as dark violet to metallic-gray crystalline solids with a pungent iodine odor. Crude iodine is widely used in the manufacture of potassium iodide (KI), iodophors, iodine-based disinfectants, and organic iodine derivatives. It also serves as a base material in halogen chemistry, X-ray contrast media, and photographic chemicals.

⚙️ Production Method

Iodine Extraction from Natural Sources

• Chilean caliche ore (primary global source): Iodate-rich ores are leached, reduced, and the iodine is precipitated and distilled.

• Brine processing: From natural gas brines or seawater, iodine is extracted using oxidation and air-stripping methods.

• The crude iodine is then sublimed and crystallized, though it retains minor halogen or moisture impurities until further refining.

❓ Frequently Asked Questions (FAQs)

---

1. What is the purity level of your crude iodine?

Answer:
Cavin Resource supplies crude iodine with a minimum purity of 99.5%, suitable for chemical and pharmaceutical applications.

---

2. Is crude iodine the same as sublimed iodine?

Answer:
No. Sublimed iodine is a further purified form of crude iodine. Crude iodine may still contain traces of moisture, halogens, or non-volatile impurities.

---

3. What safety precautions are necessary for handling iodine?

Answer:
Iodine is a strong oxidizer and should be stored in cool, dry areas, away from flammables. PPE like gloves, masks, and safety glasses are essential during handling.

4. Do you offer export support for regulated shipments?

Answer:
Yes. We provide all export documentation, including SDS, MSDS, Dangerous Goods certification, and can assist with SGS inspection and import requirements.
