Free from mechanical impurities; features a low peroxide value and is resistant to oxidation and rancidity.
High purity oleic acid is a refined-grade oxidized ore flotation collector, presenting as a colorless to pale yellow oily liquid. It features high purity, minimal impurities, and a mild odor. It is mainly used in the separation of high-end oxidized ores such as rare earths, tungsten-tin, and high-quality fluorite, suitable for fine mineral processing techniques. It can also be applied in the purification of high-end minerals and is widely used in high-end mineral beneficiation.
Product advantages
The purity of high-purity oleic acid far exceeds that of ordinary industrial-grade oleic acid, with extremely strong collector selectivity, significantly enhancing the grade of concentrate. High purity oleic acid has stable composition, is resistant to low temperatures and hard water, and maintains its efficacy under complex conditions. The foam is fine and easy to control, facilitating subsequent dewatering. It contains no additional impurities that could interfere with the quality of the concentrate, meeting the requirements of high-standard mineral processing.
Safety, Storage, and Transport
This substance is a flammable organic compound; keep away from open flames, high temperatures, and strong oxidizing agents.
Store under a nitrogen atmosphere in a cool, dark, and temperature-controlled environment to prevent oxidation and yellowing caused by exposure to air.
Transport as a standard fine chemical product, taking precautions against rain, direct sunlight, and leakage.
Avoid prolonged skin contact; wear protective gloves when handling.
FAQ
Q1: What are the differences from ordinary industrial oleic acid?
A: It has higher purity, less impurities, stronger selectivity, and is suitable for high-end mineral processing scenarios.
Q2: What are the storage requirements?
A: Store it in a sealed, light-proof container at low temperature to prevent oxidation and deterioration, and extend the shelf life.
Q3: Are special protective measures required during operation?
A: It has extremely low irritation. Wearing regular gloves and maintaining good ventilation are sufficient for normal operation.
