Product Details

Product Features

Potassium butyl xanthate (PBX) and Sodium butyl xanthate (SBX) are chemical reagents commonly used in the mining industry for froth flotation. They work by selectively binding to sulfide mineral particles, making them hydrophobic and allowing them to attach to air bubbles for separation from waste material.

Key Properties and Characteristics

Appearance: Typically a light yellow to gray-white powder or pellet with a strong odor.
Solubility: Highly soluble in water and alcohol, dissociating into xanthate ions that react with metal cations.
Chemical Formula: PBX is C₄H₉OCSSK and SBX is C₄H₉OCSSNa.
Stability: Stable under normal conditions but can decompose with exposure to acid, heat, moisture, or strong sunlight.

Safety and Handling

Proper safety measures are essential:

Storage: Store in a cool, well-ventilated area away from moisture, heat, sunlight, and fire.
Handling Precautions: Use appropriate PPE to avoid direct contact with skin and eyes.
Environmental Impact: Handle and dispose of correctly to avoid environmental harm.

Product Applications

PBX and SBX are mainly used in mining to concentrate valuable minerals:

Sulfide Ore Flotation: Effective in the flotation of non-ferrous metal sulfide ores like copper, lead, zinc, and nickel.
Specific Mineral Targeting: Particularly suitable for chalcopyrite, sphalerite, and pyrite.
Selective Separation: Can selectively separate copper sulfide from iron sulfide minerals and are used in sphalerite flotation after copper sulfate activation.

Other Uses

Sodium butyl xanthate also has applications in other industries:

Rubber Manufacturing: Used as a vulcanization accelerator in rubber production.
Agricultural Chemicals: Serves as a raw material for certain herbicides, bactericides, and pesticides
