Product Description:
Sodium Butyl Xanthate (SBX) is a highly effective flotation collector widely utilized in the mineral processing industry. Renowned for its efficiency, it facilitates the separation of valuable minerals from gangue via the froth flotation method. As an organic sulfur compound, SBX chemisorbs onto the surface of mineral particles, rendering them hydrophobic and enabling selective collection in the froth phase.

Xanthate compounds belong to a unique class of organic sulfur chemicals that are predominantly utilized as flotation collectors in the mining and mineral processing sectors. They adeptly enhance the separation of precious minerals from waste by rendering the minerals hydrophobic, thus promoting their attachment to air bubbles.
Xanthates chemisorb onto the surface of mineral particles, making them hydrophobic. This hydrophobic nature, in the presence of air and water, leads the mineral particles to cling to air bubbles. These bubbles rise to the surface, creating a mineral-rich froth that can be separately collected from the water and residual waste materials.
Widely used xanthates in the industry include Sodium Ethyl Xanthate (SEX), Sodium Isopropyl Xanthate (SIPX), Sodium Butyl Xanthate (SBX), and Sodium Isoamyl Xanthate (SIX). Each type boasts unique properties, making them ideal for specific ores and flotation conditions.
Selecting the appropriate xanthate hinges on factors such as the type of ore being processed, the desired mineral recovery rate, the pH level of the flotation environment, and the compatibility with other reagents used during the flotation process.
When handling xanthates, it is crucial to wear personal protective equipment (PPE) like gloves, safety goggles, and masks. Always handle xanthates in a well-ventilated area to avoid inhaling vapors or dust. In the event of skin or eye contact, rinse immediately with ample water and seek medical advice if necessary.
Store xanthates in a cool, dry, and well-ventilated area, away from direct sunlight and heat. Ensure containers are tightly sealed to prevent contamination and evaporation, preserving their efficacy.
In the pharmaceutical realm, xanthates serve as intermediates in the synthesis of various drugs and act as chelating agents in the production of metal-based pharmaceuticals.
Absolutely, xanthates find applications beyond mining. They are used in the rubber industry as accelerators, in textiles for dye fixation, and in water treatment as biocides.
The optimal xanthate dosage is contingent on factors like ore type, particle size, and the desired separation efficiency. Conducting small-scale tests is recommended to ascertain the precise dosage tailored for your specific application.
