Isopentyl xanthate sodium is a long-chain type sulfide ore flotation collector. It is a light yellow crystalline solid that is easily soluble in water. It has a strong collecting ability and is mainly used for the separation of multi-metal sulfide ores such as copper, lead, zinc, gold, and silver. It is particularly suitable for low-grade and difficult-to-select ores and has strong applicability in complex pulp environments.
- Appearance: Pale yellow to yellow-green powder or granules, possessing a pungent odor.
- Solubility: Easily soluble in water, dissociating into xanthate anions; hygroscopic.
- Stability: Stable at ambient temperatures; decomposes upon contact with strong acids to produce carbon disulfide; high temperatures and humid environments accelerate decomposition and loss of efficacy.
- Density: Approx. 1.20 g/cm³ (20°C)
Safety and Storage/Transport
Hazardous Characteristics
Irritating; highly hygroscopic; releases toxic CS₂ gas upon contact with acids.
Storage
Store in a cool, dry place; protect from moisture, direct sunlight, and fire hazards. Shelf life: 6 months.
Transport
Transport as a general chemical; avoid exposure to rain and direct sunlight; keep away from strong acids.
Product advantages
The floating force is superior to that of ordinary butyl xanthate. The minerals float quickly. The selectivity is good, which can reduce the impurities mixed in the gangue minerals. It has strong stability in alkaline pulp and good resistance to impurity interference. The foam volume is moderate, which is convenient for subsequent pulp dewatering treatment. The dosage of the reagent is low, and the overall cost can be controlled in the long term.
FAQ
Q1: What's the difference between this and butyl yellow reagent?
A: The carbon chain is longer, the wetting ability is stronger, and it is more suitable for low-grade and difficult-to-select ores.
Q2: What should be noted when storing?
A: Store in a sealed and dry place, avoid moisture and light, and prevent deterioration due to moisture absorption.
Q3: Do protective measures need to be taken during operation?
A: It has a slight irritant effect. Wearing gloves and a mask and maintaining ventilation is sufficient.
