Product Description:
Sodium Butyl Xanthate (SBX) is a highly effective flotation collector predominantly used in the mineral processing industry. This exceptional reagent enhances the separation of precious minerals from gangue material through the froth flotation technique. As an organic sulfur compound, SBX adheres to the surface of mineral particles, rendering them hydrophobic and facilitating their selective collection in the froth phase.

Xanthate compounds are a specialized class of organic sulfur chemicals, predominantly utilized as flotation collectors in the mining and mineral processing sectors. These compounds significantly enhance the separation process by making valuable minerals hydrophobic, thus enabling their attachment to air bubbles and effectively distinguishing them from waste materials.
Xanthates function by chemically adsorbing onto the surfaces of mineral particles, turning them hydrophobic. When air and water are present, this property causes mineral particles to attach to air bubbles. These bubbles rise to create a mineral-rich froth at the surface, which can then be easily separated from the remaining liquid and waste substances.
The industry widely uses various types of xanthates such as Sodium Ethyl Xanthate (SEX), Sodium Isopropyl Xanthate (SIPX), Sodium Butyl Xanthate (SBX), and Sodium Isoamyl Xanthate (SIX). Each variant is tailored with specific properties that suit different types of ores and flotation environments.
The selection of a suitable xanthate is influenced by factors such as the type of ore being processed, the required mineral recovery rate, the pH level of the flotation medium, and compatibility with other flotation reagents.
When handling xanthates, it is crucial to wear personal protective equipment (PPE), including gloves, safety goggles, and masks. Ensure usage in well-ventilated spaces to avoid inhaling vapors or dust. In case of skin or eye contact, promptly rinse with plenty of water and seek medical attention if necessary.
Xanthates should be stored in a cool, dry, and well-ventilated environment, away from direct sunlight and heat sources. Ensure containers are tightly sealed to prevent contamination and evaporation.
In the pharmaceutical industry, xanthates serve as intermediates in the synthesis of certain drugs and act as chelating agents in the development of metal-based pharmaceuticals.
Absolutely, xanthates find applications beyond mining. They are used as accelerators in the rubber industry, for dye fixation in the textile industry, and as biocides in water treatment processes.
Determining the optimal xanthate dosage involves considering factors like the type of ore, particle size, and the desired efficiency of separation. Performing small-scale tests is recommended to identify the precise dosage required for your specific application.
