Potassium Ethyl Xanthate (PEX) is a widely used flotation reagent in the mining industry. It functions as a strong collector for sulfide ores. It is especially effective for copper, lead, zinc, and nickel sulfide minerals.

PEX offers a balance between selectivity and collecting power. It is suitable for both bulk flotation and selective flotation processes.

Key Features

• Strong collecting ability for sulfide minerals

• Good selectivity performance

• High recovery efficiency

• Stable quality with consistent performance

• Suitable for various flotation systems

  
  

PEX is commonly selected when medium to strong collecting strength is required.

Applications
