Description

Butylxanthate is a specialized organic sulfur compound widely utilized as a powerful collector in mineral processing. Its primary value lies in its exceptional selectivity and efficiency for the flotation of sulfide ores, enabling the economic recovery of valuable metals. This reagent is essential for mining and metallurgical operations focused on copper, lead, zinc, and nickel extraction, where maximizing mineral yield and purity is critical.

Application

• Sulfide Ore Flotation: Primary collector for the selective recovery of copper, lead, zinc, and nickel sulfide minerals from ore.
• Copper-Molybdenum Separation: Used in differential flotation circuits to depress copper sulfides and float molybdenite.
• Platinum Group Metal (PGM) Recovery: Aids in the concentration of PGM-bearing sulfide ores.
• Gold Recovery: Employed in the flotation of gold-bearing pyrite and arsenopyrite ores.
• Industrial Effluent Treatment: Acts as a precipitating agent for the removal of heavy metal ions from wastewater.
• Chemical Synthesis Intermediate: Serves as a reagent in organic synthesis for introducing xanthate functional groups.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking and reduced efficacy.
