Product Description:
Sodium Butyl Xanthate (SBX) serves as a pivotal flotation collector in the mineral processing realm. This efficient reagent excels in separating valuable minerals from gangue via the froth flotation technique. SBX, an organic sulfur compound, adheres to mineral particle surfaces, rendering them hydrophobic. This facilitates their selective collection in the froth phase.

Storage Conditions:
Xanthate compounds represent a unique class of organic sulfur chemicals primarily utilized as flotation collectors in the mining and mineral processing industries. These compounds significantly enhance the separation of valuable minerals from waste materials by rendering the minerals hydrophobic, thus facilitating their attachment to air bubbles.
Xanthates operate through chemisorption onto the surfaces of mineral particles, which makes them hydrophobic. When air and water are present, this hydrophobic nature causes mineral particles to attach to air bubbles. These bubbles rise to the surface, forming a mineral-rich froth that can be easily separated from the remaining water and waste materials.
Industrially common types of xanthates include Sodium Ethyl Xanthate (SEX), Sodium Isopropyl Xanthate (SIPX), Sodium Butyl Xanthate (SBX), and Sodium Isoamyl Xanthate (SIX). Each type is endowed with specific properties that make them particularly suitable for varying ores and flotation conditions.
Selecting the right xanthate involves considering factors such as the type of ore being processed, the desired mineral recovery rate, the pH levels of the flotation environment, and the compatibility with other reagents used in the flotation process.
Handling xanthates requires stringent safety precautions. Personal protective equipment (PPE) like gloves, safety goggles, and masks should be worn. Ensure usage in a well-ventilated area to avoid inhaling vapors or dust. In cases of skin or eye contact, immediately flush the area with plenty of water and seek medical advice if necessary.
Store xanthates in a cool, dry, and well-ventilated area, keeping them away from direct sunlight and heat sources. Ensure containers are tightly sealed to prevent contamination and evaporation, maintaining the integrity of the chemical.
Within the pharmaceutical industry, xanthates serve as intermediates in the synthesis of certain drugs and act as chelating agents in developing metal-based pharmaceuticals.
Certainly, xanthates extend their utility beyond mining. They are employed in the rubber industry as accelerators, in the textile industry for dye fixation, and in the water treatment industry for biocide applications.
Determining the optimal xanthate dosage involves considering factors such as ore type, particle size, and desired separation efficiency. It is advisable to conduct small-scale tests to ascertain the appropriate dosage tailored to your specific application.
