Product Description:
Sodium Butyl Xanthate (SBX) is a highly effective flotation collector extensively used in the mineral processing industry. This potent reagent excels in separating valuable minerals from gangue through the froth flotation method. As an organic sulfur compound, SBX binds strongly to the surface of mineral particles, rendering them hydrophobic and facilitating their selective collection in the froth phase.
Key Features:
- High Efficiency: SBX significantly enhances the selective flotation of sulfide and other minerals, boosting the efficiency of mineral recovery.
- Versatility: Compatible with a wide range of ore types and can be combined with other flotation reagents for tailored separation processes.
- Stability: Demonstrates stability across various pH conditions, making it ideal for different flotation environments.
- Environmental Consideration: Although all xanthates require careful handling, SBX is biodegradable and has a reduced environmental impact compared to some other collectors.
Applications:
- Froth Flotation: Utilized in the flotation of non-ferrous and precious metal ores, including copper, lead, zinc, and others.
- Mineral Processing: Enhances the efficiency of mineral beneficiation processes, resulting in higher recovery rates and purer end products.
Safety Information:
- Use appropriate personal protective equipment (PPE), such as gloves, safety goggles, and a mask, when handling SBX.
- Avoid skin and eye contact. In case of contact, rinse immediately with plenty of water and seek medical advice if necessary.
- Ensure proper ventilation to avoid inhaling vapors or dust.
Storage Conditions:
- Store in a cool, dry, and well-ventilated area away from direct sunlight and heat sources.
- Keep containers tightly sealed to maintain product integrity and prevent contamination.

What are xanthate compounds?
Xanthate compounds belong to an essential class of organic sulfur chemicals. Primarily utilized in the mining and mineral processing industries, these compounds act as flotation collectors, significantly amplifying the separation of valuable minerals from waste. By rendering the minerals hydrophobic, xanthates facilitate their attachment to air bubbles, streamlining the extraction process.
How do xanthates work in froth flotation?
Xanthates operate through chemisorption onto mineral particles' surfaces, imparting hydrophobicity. In the dynamic environment of air and water, this hydrophobicity causes mineral particles to attach to air bubbles. These bubbles, rich with mineral particles, ascend to form a froth at the surface, enabling the collection of mineral-rich froth separately from the residual water and waste.
What are the common types of xanthates used in industry?
In the industry, prevalent xanthate types include Sodium Ethyl Xanthate (SEX), Sodium Isopropyl Xanthate (SIPX), Sodium Butyl Xanthate (SBX), and Sodium Isoamyl Xanthate (SIX). Each variant boasts unique properties, making them ideally suited for distinct ores and specific flotation conditions.
Which factors influence the choice of xanthate for a particular application?
Selecting the appropriate xanthate involves considering several factors: the specific type of ore undergoing processing, the desired mineral recovery rate, the flotation environment's pH, and compatibility with other reagents employed in the flotation process.
What safety precautions should be taken when handling xanthates?
When handling xanthates, it is crucial to employ personal protective equipment (PPE), such as gloves, safety goggles, and masks. Use these chemicals in well-ventilated areas to avoid inhalation of vapors or dust. In the event of skin or eye contact, immediately flush the area with plenty of water and seek medical advice if needed.
How should xanthates be stored?
Store xanthates in a cool, dry, and well-ventilated space, away from direct sunlight and heat sources. Ensure that containers are tightly sealed to prevent contamination and evaporation, maintaining the integrity and effectiveness of the compounds.
What is the role of xanthates in the pharmaceutical industry?
Within the pharmaceutical sector, xanthates serve as pivotal intermediates in synthesizing particular drugs. Additionally, they act as chelating agents, facilitating the development of metal-based pharmaceuticals, thereby contributing to medical advancements.
Can xanthates be used in applications other than mining?
Absolutely. Beyond mining, xanthates find utility in diverse industries. In the rubber sector, they function as accelerators. In textiles, they aid in dye fixation, and in water treatment, they serve as biocides. Their versatility extends their utility across various industrial applications.
How do I determine the correct dosage of xanthate for my process?
Determining the optimal xanthate dosage hinges on factors such as ore type, particle size, and desired separation efficiency. Conducting small-scale tests is advisable to ascertain the precise dosage tailored to your specific application, ensuring maximal efficiency and effectiveness.
