Product Description:
Sodium Butyl Xanthate (SBX) is a highly effective and widely employed flotation collector within the mineral processing industry. This reagent is instrumental in the efficient separation of valuable minerals from gangue via the froth flotation technique. As an organic sulfur compound, SBX chemisorbs onto the surface of mineral particles, rendering them hydrophobic and facilitating their selective collection in the froth phase.

Xanthate compounds are specialized organic sulfur chemicals employed predominantly as flotation collectors in the mining and mineral processing sectors. They significantly boost the separation efficiency of valuable minerals from waste by rendering the minerals hydrophobic, thereby aiding their attachment to air bubbles.
Xanthates function by chemisorbing onto the surfaces of mineral particles, making them hydrophobic. When air and water are introduced, these particles adhere to air bubbles, rising to the surface to form a mineral-rich froth that can be subsequently separated from the water and residual waste materials.
Industry-standard xanthates include Sodium Ethyl Xanthate (SEX), Sodium Isopropyl Xanthate (SIPX), Sodium Butyl Xanthate (SBX), and Sodium Isoamyl Xanthate (SIX). Each variant possesses unique properties tailored for different ores and flotation conditions.
Selecting the appropriate xanthate hinges on the type of ore processed, the targeted mineral recovery rate, the flotation environment's pH levels, and compatibility with other flotation reagents.
When handling xanthates, it is imperative to wear personal protective equipment (PPE) such as gloves, safety goggles, and a mask. Work in a well-ventilated area to avoid inhalation of vapors or dust. In case of skin or eye contact, rinse immediately with plenty of water and seek medical advice if necessary.
Store xanthates in a cool, dry, and well-ventilated space, away from direct sunlight and heat sources. Ensure containers remain tightly sealed to prevent contamination and evaporation.
In the pharmaceutical field, xanthates serve as intermediates in the synthesis of various drugs and as chelating agents in developing metal-based pharmaceuticals.
Indeed, xanthates have diverse applications beyond mining. They function as accelerators in the rubber industry, assist in dye fixation in the textile industry, and act as biocides in water treatment.
Determining the optimal xanthate dosage depends on variables such as ore type, particle size, and the desired separation efficiency. Conducting small-scale tests is advisable to identify the ideal dosage for your specific application.
